When we looked at gene expression, we found fairly small changes in 65 million years of the macaque, orangutan, and chimpanzee evolution.

Although modern humans must now rely on dogs to sniff out drugs and other contraband at airports, our early ancestors may have been capable of the job themselves!

No other animal relies on cooked food. Perhaps something in the cooking process altered the biochemical requirements for maximal access to nutrients as well as the need to process the natural toxins found in plant and animal foods.

It involves very little effort to create a huge effect.

The big question is why are humans so different?

It looked quite disturbing and fairly shocking. But I strongly believe that when we come out the other side, we are going to be pleased with our improved park.
