The Khoe and San peoples in southern Africa play an important role for our understanding of the evolutionary history of humans. These peoples are directly descended from the first branching of the genealogical tree of today’s humans. This is shown in a study led by Uppsala University researchers and being presented in the early online version of the journal Science today.

Robert Titzer, an educator with a doctorate in human performance from Indiana University, and his company claimed that more than a million families successfully used the “Your Baby Can Read” program and that they had studies to back up these claims. The FTC on the other hand says those studies were flawed.

This article is about scientist that have figured out that they can grow sperm from skin cells. A university figured out that maybe human embryonic stem cells and human induced pluripotent stem cells can become sperm cells. This article is so interesting. I can't believe that this could actually happen. The negative thing about this is that If this is possible, imagine how much more the population is going to increase. I can't wait to see what else we're going to figure out.

this article was about how scientist have figured out how to make sperm from skin cells. they figured out that skin had some of the same properties that was in sperm. tjis article was interesting because i didn't think skin could be sperm.

We have generally believed that animals are not capable of very complex thought, even though many species use tools and engage in other complex behaviors. This study looks at whether New Caledonian crows, that were caught just for this experiment, are capable of attributing actions to a hidden cause, when they see that possible cause come and go.

The point of marriage, after all, is to grow old with someone and develop a sense of trust. Infidelity happens in half of all marriages. Many end in divorce. The institution of marriage seems to be in big trouble, but Ryan says an understanding of the way humans evolved can help us cope.
