A biologist has confirmed the sighting of a real Michigan wolverine, about 200 years after the species was last seen in the state that uses the small but ferocious animal as its unofficial nickname.
Coyote hunters spotted a wolverine near Ubly, about 90 miles north of Detroit. Michigan Department of Natural Resources wildlife biologist Arnie Karr saw the forest predator Tuesday and snapped pictures of the animal as it ran out of the woods and across a field.
The wolverine, a member of the weasel family that grows to about 25 pounds but is ferocious enough to fight off bears and wolves, once ranged across the northern and western United States. It is now limited mostly to northern Canada, Idaho and Alaska, with sightings in a few other states, but its last confirmed sightings in Michigan were by fur traders in the late 1700s and early 1800s.
The appearance is "up there with having a caribou or a polar bear turn up," Department of Natural Resources spokesman Brad Wurfel said Wednesday. "It's unprecedented."

From GS News -
Scientist discovered the lioness/lion, called Mmamoriri, on the plains of the Okavango Delta in Botswana, southern Africa.
They believe evolution is helping the lionesses there grow manes so they fool invading prides into thinking they are males – helping their survival.
Mmamoriri in particular not only has a mane but also a deeper and more masculine roar.
If that’s enough to scare off other prides trying to invade her family’s territory, it will be a big genetic advantage – helping her pride’s cubs survive.
The scientists believe there are five other lions in the area with the same evolutionary adaptation, meaning they have higher male hormone levels.
Mmamoriri is one of the stars of the new documentary, The World’s Sneakiest Animals, which will be shown in Britain on BBC2 at 6.30pm on Christmas Day.

From Metro UK -
The first full genome sequence shows of that octopuses (NOT octopi) are totally different from all other animals – and their genome shows a striking level of complexity with 33,000 protein-coding genes identified, more than in a human.
There we were thinking it was quite freaky enough when they learned how to open jam jars.
US researcher Dr Clifton Ragsdale, from the University of Chicago, said: ;The octopus appears to be utterly different from all other animals, even other molluscs, with its eight prehensile arms, its large brain and its clever problem-solving abilities.

scientists discover ancient 3 armed sea monster unlike any living species
If you were to travel back 550 million years ago, you would be forgiven for thinking that you’d accidentally arrived on an alien planet. The Earth’s ecosystem, entirely confined to the ocean, would have been populated by primitive and bizarre organisms. One such sea monster is the Tribrachidium, a three-armed sea creature that is unlike any living thing found today.
Analyzing the unique form of Tribrachidium was a challenge for researchers. “Because we have no obvious modern comparison, that’s made it really hard to work out what this organism was like when it was alive — how it moved, if it moved, how it fed, how it reproduced,” says Imran Rahman, research fellow at University of Bristol and lead researcher on a recent study of Tribrachidium. The research team created a digital model of Tribrachidium using a fossil mold. This model was then inserted into simulations which recreated various current flows that Tribrachidium may have encountered in the shallow seas of the Ediacaran.

Prehistoric cave prints show most early artists were women
Alongside drawings of bison and horses, the first painters left clues to their identity on the stone walls of caves, blowing red-brown paint through rough tubes and stenciling outlines of their palms. New analysis of ancient handprints in France and Spain suggests that most of those early artists were women.
This is a surprise, since most archaeologists have assumed it was men who had been making the cave art. One interpretation is that early humans painted animals to influence the presence and fate of real animals that they'd find on their hunt, and it's widely accepted that it was the men who found and killed dinner.
But a new study indicates that the majority of handprints found near cave art were made by women, based on their overall size and relative lengths of their fingers
