Meet the rat-sized common ancestor of mammals

It lived 66 million years ago, and it might be your ancestor:

Humankind’s common ancestor with other mammals may have been a roughly rat-size animal that weighed no more than a half a pound, had a long furry tail and lived on insects. In a comprehensive six-year study of the mammalian family tree, scientists have identified and reconstructed what they say is the most likely common ancestor of the many species on the most abundant and diverse branch of that tree — the branch of creatures that nourish their young in utero through a placenta. The work appears to support the view that in the global extinctions some 66 million years ago, all non-avian dinosaurs had to die for mammals to flourish.

Frozen Inca girl

Amazing story of a well-preserved 500 year old Inca girl who was sacrificed 500 years ago. Sad story too.

Judging from the condition of the body, it is believed that she was drugged and left to die in the mountains. It would not have taken much time for her to die due to the high exposure. The Incan high priests took their victims to high mountaintops for sacrifice. As the journey was extremely long and arduous, especially so for the younger victims, coca leaves were fed to them to aid them in their breathing so as to allow them to reach the burial site alive. Upon reaching the burial site, the children were given an intoxicating drink to minimize pain, fear, and resistance, then killed them either by strangulation, a blow to their head or by leaving them to lose consciousness in the extreme cold and die of exposure.
