- KO> O Most hominin species, including Homo sapiens, arose in Africa. It is sometimes possible to extract DNA from ancient humans (of our species and closet cousins) for analysis. The oldest hominin DNA ever sequenced came from a 400,000-year-old thighbone. Comparisons among ancient remains and population of humans around the world have yielded insights into when and how various Homo species migrated out of Africa. The diagram below shows a comparison of DNA sequence from different human groups. position 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 首 Dinka G G A C G C T G Italian G T. C T T.

Their native habitat is a forest and they mostly live in trees. The island has few trees and the lizards spend most of their time on the ground where they are eaten by snakes. Over many generations the island population of lizards develop shorter toes and longer legs which allow them to run faster on bare ground. The lizards withe longest legs/shortest toes are the least likely to be caught be snakes. After several decades lizards are collected from the island and placed in enclosures. Lizards from the original forest habitat are placed in identical enclosures. Each type of lizard mates and has offspring. The offspring resemble their parents and the offspring of island lizards have shorter toes/longer legs than offspring of forest lizards (i.e the differences you see in nature are also found in a lab setting).
