An egg-laying, spiny mammal with a four-headed penis is already pretty bizarre, but it turns out short-beaked echidnas are even stranger than we thought. Weighing up to nine pounds (four kilograms) and resembling a big hedgehog, the short-beaked echidna is one of only three species of monotremes—or egg-laying mammals—left in the world, along with the platypus and long-beaked echidna. Thanks to their unusually large and complex brain, the mammals are also smart: Nicol recounted one incident in which his team found a wild echidna that had lost its radio transmitter and needed a new one. When the critter spotted the team from across a field, “you could see it run like crazy because it knew what was happening. Both males and females hibernate in burrows, but the males often wake up earlier and sneak into females’ burrows, where they mate with the still-hibernating animals. In general, females are promiscuous, mating with a lot of males, and continue to mate even when pregnant. Big testes usually imply stiff competition for promiscuous females, which is certainly true for echidnas—it’s common to see up to ten males pursuing an individual female. Another example of the intense competition for females is what happens to the testes during hibernation.
After a three-week pregnancy the female echidna makes a nursery burrow, where she lays her egg directly into her pouch, incubating it for ten days until it hatches into a baby. The female then feeds the baby with milk for another five to six weeks, before she leaves the burrow to forage. While the mother is in the nursery with her egg or the newborn baby males may try to break into the burrow, presumably to mate with the female again. If this happens the young dies—“we don’t know exactly how, but presumably just by being dislodged from the mother’s pouch”— which would make the female come into heat again. Interestingly, the only males that break into the nursery burrows are the ones she hasn’t mated with yet, suggesting the males know which females they’ve already mated with. Overall, Nicol said, his research on Tasmanian echidnas boosts overall knowledge of the animals, which could help save the critically endangered long-beaked echidna of New Guinea.
I’d like to know what is evolutionally different among the different types of echidna. We’re Moving!As of October 22, 2014, Weird & Wild will be hosted on National Geographic's main news site. Baby elephants are born big, standing approximately three feet (one meter) tall and weighing 200 pounds (91 kilograms) at birth. When she was born, Louise Brown became a kind of scientific celebrity, making headlines around the world. I recall in 2004 when the media reported that Louise had gotten married, to a bouncer named Wesley Mullinder. As someone who cares about both people and the planet, I’ve long had mixed feelings about IVF.
I wouldn’t want to tell that family what to do in their own lives, but I did ask the reporters if they had considered whether some people might think those resources could be better spent elsewhere, such as feeding starving children somewhere or helping families adopt children from disadvantaged areas. An older woman sitting a few rows in front of me in the auditorium turned around and gave me a blistering, withering look.
When I worked for E Magazine, we wrote a lot about human population and its effects on our environment. At E, readers told us on several occasions that they had consciously opted to never have kids specifically out of concern for the environment.
Others left impassioned comments on our stories to the effect that we should never try to restrict growth, we should put our emphasis on changing the way we live. As recent dustups over adoption in Russia and elsewhere suggest, it’s no simple task to simply move people from one place to another, and there can be cultural, ethical, and economic ramifications. It is extremely understandable that couples would do everything in their power to create life after their own fashion. When it comes to individuals like Louise Brown, my celebrity birthday doppelganger, it seems inappropriate to suggest that they shouldn’t have been given a chance. Well that’s ok the deaf chap is allowed choice,but what he is not allowed(thank God) is to make choices for other deaf people, who would prefer to have a man made solution to their problem. I believe God works through humans in the form of kindness, talents and skills, Brian, but l do realise that so does the Devil, and he can create badness, madness, monstrousities, so mankind has to be careful.
I wish you were a little more gracious in your reply to me but l guess it is a sign that you realise l am quite formidable, so that is a compliment in a back handed way. Just to say, l too would have concerns about some issues of technology going forward, for example; hibrid births or male pregnancy. In regards to IVF, l believe God is in the equation, for the good gift given to The World, in regards to by passing a faulty reproductive system, and in that respect restoring a woman to a fertile status as that which compliments nature as in the natural order. To explain further; some people think that the creation of life within an artificial incubator is wrong and infertile couples should be left to their misery.
Professor Robert Edwards and Dr Patrick Steptoe, gave a great service to the world and in keeping with God and Nature.
I would also like to say that l agree that Mankind should respect the Planet, but as a Christian, we should be careful not to worship it as you are in danger of doing, Brian. To go on about population figures being added to by unnatural means through IVF is ridiculous and wrong minded.
Obviously, 5 million humans created by IVF in the whole of the world, is a big figure to a small mind! Obviously, more lives COULD be saved by pooling all the money used for helping infertile couples and IVF together, the work and hours put in are truly tremendous just to create one child; when already there are so many who could use help.
So if you or your spouse is infertile, and you do desperately want a child of your own genetic make-up, it should be your own personal choice.
BUT I am also very supportive of those who chose to adopt and even those who become foster parents.
And a secondary side note, simply adoption instead of going through IVF is not nearly as easy as people would like to believe it is. I’d also point out that while IVF has become common and widely accepted, there are still major ethical objections to the fact that for every baby born, several other viable embryos are killed, used in research, or frozen indefinitely.

Two years after being discovered deep in a South African cave, the 1,500 fossils excavated during the Rising Star Expedition have been identified as belonging to a previously unknown early human relative that National Geographic Explorer-in-Residence Lee Berger and team have named Homo naledi. With at least 15 individuals of all ages and both sexes represented, the find adds an unprecedented amount of information to our understanding of early human evolution in Africa. In addition, the absence of any other animal remains or large debris in the fossil chamber strongly suggests that these non-human beings intentionally deposited their dead within this cave. An Asiatic leopard cub in the Hukawng Valley in Myanmar (Burma) became an orphan after hunters killed its mother to sell her body parts for use in traditional medicine. A Bengal tiger called Sita gives her cubs an early morning bath in India’s Bandhavgarh National Park. Three of the eight tiger subspecies became extinct in the 20th century, hunted as trophies and also for body parts that are used in traditional Chinese medicine. See how National Geographic is supporting on-the-ground conservation projects to save big cats. The king of the African savannah is in serious trouble because of massive conversion of the continent’s remaining wilderness to human land-use, according to a detailed study. Intensely shy and hovering on the edge of extinction, Iranian cheetahs are essentially impossible to see. Thinking of snow leopards as domesticated—and thus dependent on people for food—may help save the dwindling species, one conservationist claims.

Laly Lichtenfeld aims to prevent lion-livestock conflict and to improve the lives of lions and people alike. When Western sailors started landing on the Falkland Islands, off the curling tip of South America, they were greeted by a bizarrely tame dog-like creature.
Some said that early South Americans must have partly domesticated the wolf and brought it over on their boats—hence its unfortunate tameness. Cooper’s speciality is wresting samples of ancient DNA from fossils, and sequencing these millennia-old molecules to better understand their owners.


In 1996, Cooper travelled to London’s Natural History Museum to check out one of only six specimens of Falkland Islands wolf that were known at the time. Darwin was meticulous and the skull had been thoroughly cleaned—great for museums, bad for geneticists. His team have since collected DNA from five of the wolves, including a 7th moth-eaten, stuffed specimen that was gathering dust in an attic at New Zealand’s Otago Museum. The date ruled out the possibility that humans brought the wolf over to the islands, but it suggested an alternative.
During the last Ice Age, four shallow ice terraces (numbered I to IV) spanned the ocean between Argentina and the Falklands.
So, 16,000 years ago, huge underwater terraces extended off the coast of Argentina, like the shallow end of a swimming pool.
Early hunters killed mastodons with mastodons (Also, you can chuck a bone spear through a car.
In his diaries, Darwin explicitly wrote that he sneaked up behind it and hit it with his geological hammer on the head.
Arguably, Darwin shouldn’t be called a naturalist at this stage in his career, not having had any official, formal training in science (he had attended some lectures while studying for the clergy), and his main interest on the trip was in geology.

Mother black bears are notoriously protective of their cubs, who stay with their mothers for about two years.
Usually solitary animals, leopard cubs live with their mothers for two years, learning how to hunt. Bobcat kittens are born in litters of one to six and will stay with their mother for up to one year before heading off on their own. Dutiful mothers, female polar bears usually give birth to twin cubs, which stay with her for more than two years until they can hunt and survive on their own. Cheetah mothers typically give birth to a litter of three cubs, all of which will stay with her for one and a half to two years before venturing off on their own.
The world’s top felines—including lions, tigers, cheetahs, and leopards—are slipping toward extinction.
Nicol added that he’s lifted a log in Tasmania and found three or four male echidnas hanging out with a single female.
In other hibernators the testes shrink during hibernation and have to be regrown when the animal warms up. She returns at five- or six-day intervals to feed the baby, and only stays with it for a few hours.
Echidnas have evolved a defense for this, which Nicol has discovered: Their milk contains proteins that inhibit the growth of harmful bacteria, thus protecting their young from illness. They nurse for two to three years, and are fully mature at 9 (females) to 15 (males) years of age.
Brown underwent an experimental procedure that would eventually be called IVF, or in vitro fertilization. And for each year afterward, the media would report on her progress, faithfully on my birthday.
Edwards was awarded the Nobel Prize in Medicine for the work that led to Louise Brown’s successful birth (done in conjunction with gynecologic surgeon Patrick Steptoe). Before Louise’s birth, the English physiologist had been working on human fertilization for years at Cambridge, despite a lack of funding from the government and a fair amount of controversy at the time. I have enjoyed following Louise Brown’s trip through life, and I wish her all the best. But at the same time, I have always wanted to ask, could IVF be placing more stress on our polluted, resource-extracted planet? The reporters explained the latest in conception-assistance technologies, and profiled a family who had spent tens of thousands of dollars trying to get pregnant.
We learned early on that it is an extremely sensitive issue, one that can divide religions, political parties, and even families.
Make cars more efficient, squeeze power from every last drop of oil, and develop new clean technologies, they said, but don’t tell people to have fewer kids.
Most industrialized countries have growth rates that have leveled off, reached replacement level, or even dipped below replacement level. There are many factors to consider, but what is perhaps most surprising is that few people seem willing to engage in the conversation about perhaps unintended consequences of various procedures. But when it comes to thinking about such technologies as IVF, and especially future technologies, it may be wise to have a broader conversation about the impacts.
But that is wrong thinking as if that was applied across the spectrum then blind people would not be assisted to see by surgeons or even spectacles. Believe it or not God has made the World and it is not as fragile as Green People imagine it to be! But going further, he argued that there is nothing wrong with him as a deaf person, it is rather a difference that also brings with it a unique culture.
I learned about the unbelievably insane number of hoops they had to clear (as a gay couple) in order to qualify as acceptable adoptive parents. Howard — my wife and I are about to undertake IVF after several years of unexplained infertility. I truly had never thought of the two sides of IVF or of other ways to increase the chance of bearing a baby.

It roamed wild across the islands, but would frequently swim out to meet the approaching boats while wagging its tail. What was such a large predator doing on this tiny set of islands, some 460 kilometres away from the South American mainland? Others said that the wolf sauntered across prehistoric land bridges, or rafted over on chunks of ice. So far, he and others have filled their genetic ark with Smilodon the sabre-toothed cat, American lion, cave lion and American cheetah. Darwin collected the animal himself, and his handwriting graces the label (although it’s unclear whether he actually clubbed it over the head himself, as some stories claim).
As Cooper turned the skull around, he noticed a tiny sinus on its face—an opening, and one that clearly had something in it. That’s useful to know, but it doesn’t tell us anything about the animal’s mysterious origins. This time, he compared the Falkland Islands wolf’s DNA with that of a close relative that lived on the mainland—the similarly extinct Duscyon avus. Frozen sheets covered much of the world and sea levels were dramatically lower than they are now.
Perhaps it behaved like modern Arctic foxes, taking advantage of the glut of seabirds, baby animals and washed-up carcasses on the frozen shoreline. That animal is now the type specimen, housed in the collections of the Natural History Museum in London. I seem to recall reading somewhere that the captain of the ship saw Darwin’s main role as providing him with intelligent companionship of the proper social status.
Things were really different almost 200 years ago, and Darwin was more a man of his time than some may have cared to admit.

After the eggs have incubated for about three months, the mother opens the nest and helps her young out of their shells. Echidnas regrow their testes before they enter hibernation, ensuring they are ready for action when they rewarm. My parents had conceived me in the old-fashioned way, but the Browns had had trouble in that department, having tried to get pregnant for nine years.
Hearing the latest on Louise became a kind of personal tradition on my special day, and to some extent, I felt like I grew up with her, although I have never met her. In 2006, the happy couple welcomed their own child, naturally conceived, a boy they named Cameron.
I remember feeling proud that I had some connection, even if only in my mind, to that milestone. I imagine some people reading this post were born through IVF, or perhaps they have children or relatives who were.
Only a few countries, mostly in sub-Saharan Africa, still have sky-high reproduction rates. Also God knows the fate of the Planet and He will decide how it ends and even has He stated that He will end it at the time of his choosing, that means only God can destroy the World and Mankind cannot do so! What these guys shared with me opened my eyes to the fact that any two people who would intentionally put themselves through this tremendous, lengthy and invasive ordeal to be approved as parents are probably as close to ideally prepared parents as is humanly possible. I loved being a parent of two children that we could watch grow into themselves while still have characteristics of their families.
BUT, the author also raises an important question about the future of our planet and the growing population, especially in some parts of the world.
If all couples had fewer children, especially in high-consuming cultures, whether by assisted means or not by assisted means, that would seem to be a more even-handed approach to what the author sees as the population-environment problem. They toured the desert islands off the southeastern coast of the Baja Peninsula and they listened to presentations by more than a dozen experts, including several whose Baja California research is funded by the Society.

Deepening the puzzle, South America is a land dominated by rodents, but none of them had made it to the Falklands. He suggested to Paula Jenkins, the museum’s curator of mammals, that he could pull out a tooth, cut off part of its root, and put it back in. His student took a bit of its toe, sequenced it, and confirmed that it was indeed a match for the other Falkland Island wolves. The DNA revealed that the two species of “foolish dogs” diverged from their common ancestor just 16,300 years ago.
The ocean floor between mainland Argentina and the Falkland Islands is incredibly flat, sloping by just 0.5 degrees for 600 kilometres. The gap between them and the mainland was just 20 to 30 kilometres wide, and 10 to 30 metres deep. The ice terraces acted as an ecological filter—a opportunity for a large predator to seize, but a forbidding no-go area for smaller animals. Loon cries are most prevalent during breeding season as pairs aggressively defend their territories.Loons have striking red eyes, black heads and necks, and white striping, checkering, and spotting on their backs. In Iran, programs to distribute free birth control and provide widespread education are often praised internationally. There are bound to be many more thorny questions with new technologies around reproduction, radical life extension, and other issues, so we need to consider all sides of the equation, both the science and the ethics. A family that is paying ten-thousand dollars each IVF procedure is more likely to have jobs, health insurance, and not be on DSHS (public assistance).
By 1880, it was extinct, but not before a young, twenty-something naturalist called Charles Darwin managed to see one for himself in 1834.
That gives a pretty good indication of when the wolf reached the Falkland Islands and started evolving independently from its mainland cousins. I’m reminded here that any couple going through the IVF process is quite likely equally committed to the future of their children. Hatchlings leave the nest on their first day and are able to fly in about 11 weeks.There are many Native American legends about common loons. I understand overcrowding of the planet is of paramount concern today, however, I do believe that this busy world is also in need of quality, child-focused parents who will, hopefully, teach their children well on every level – but especially with regard to care and responsibility for the Earth.
I also have 3 nephews and 1 niece (my sister passed away several years ago) and I have so enjoyed watching them become adults who have so far produced 6 girls and 1 boy – my GREAT GRANDS.
Loon populations are currently stable, but a number of threats loom, including human encroachment and pollution. Each child clearly resembles someone in our family, be it parent, uncle, aunt, Grandparent or GRAND aunt. I would never ask anyone to give up that joy because of adding more humans to our already burgeoning population.
