ANTH 1001 Lecture Notes - Macroevolution, Soot, Ulna
Document Summary
Every species has come into existence, coincident in both space and time, with a pre-existing, closely allied species -- This is not a theory of evolution, but a thesis, composed of multiple theories: species change (evolution as such, all organisms share a common ancestry. Moths (black and white, black (soot covered) and white bark on trees) Macaca fuscata (japanese snow macacs) taken to texas and oregon those in texas got significantly smaller, and those in oregon became significantly larger. Texas population develops longer limbs and oregon population develops larger trunks. Differences in development patterns changes already present in 2nd generation common ancestor -- 4 billion years ago. Morphological evidence: evidence from the shapes of organisms and their structures forelimbs in tetrapods all share same basic structure (humerus, ulna, radius) growth and development of animals. Genetic evidence helps determine what the ancestry looked like gene similarities and the functions of those genes.
