Document Summary

Evidence for evolution part 2 review ppt: chromosomes (refer to ppt for diagrams, humans 23 pairs of chromosomes (46, chimps 24 pairs of chromosomes (48, what happened to that chromosome, predictions: It was lost, we didn"t need those genes. When god made us he distributed the genes differently, didn"t need as many chromosomes. There has been a fusion event: compelling evidence for. Common ancestry: predictions based on evolution: If life originated on earth in the distant past and then evolved, we should see evidence in the fossil record. If evolution occurred within lineages, and those lineages sometimes split then we should see change in species or morphology through the fossil record. If creatures share a common ancestry, then we should see transitional forms. We should be able to see evidence of natural selection. If life originated on earth in the distant past and then evolved.
