My Friends Newborn Baby Was Born With The Same Birthmark In Her Hair As Her Mother Most of us have a birthmark somewhere on our skin, but this mom and daughter share one on their head. This DNA mutation is calledPoliosisand results in the absence of melanin on any hairy part of the ...
We share almost 99 percent of our DNA with our closest relatives, chimpanzees, but have you ever wondered why they have never evolved as fast as we have? The answer is our complex brain. The earliest human brains from around 2 million years ago were only big enough to deal with simple s...
and what I study in that case is the way that people have dealt with anatomy -- meaning human bodies, animal bodies -- how they dealt with bodily fluids, concepts of bodies; how have they thought about bodies. The other hat that I've worn in my ...

First, scientists must collect DNA from the bodies of extinct animals. Then they will put it in the eggs of similar animal species. When these animals become adults, they will have babies. And these baby animals will have the DNA of the extinct animals. Scientists believe it is possible t...
