Gobbling Up The Family Tree: Understanding our phylogenetic tree

It’s Thanksgiving. Your mom and dad are debating the art of properly basting a turkey, while grandma is showing you and the rest of the grandkids your family tree. By now, you’ve noticed how long and complicated your tree is. Along with parents, grandparents and great-grandparents, there are second cousins, great aunts, great grand nieces, etc. And, while you may have never known these people directly, all are in some way related to your family and yourself. But what about the family tree that extends beyond your ancestral family tree?

Lucy’s Paleo Diet: How teeth reveal important insight into early hominin diet

So, you’re at the dentist office. While sitting in the waiting room, you pick up one of the many magazines. On the cover, is a title heralding a new dietary trend; the Paleo Diet.

However, upon closer inspection, I see the vague tinges of shade difference. So, when presented with such an array of colors and all the designating names categorizing them, I realize that we humans have a deep understanding of color variation. This ability to see color has allowed us to note the vast diversity of skin color among our own species.

Supervillain or Superhero? The effects of autosomal recessive disorders on human evolution
