So.. again… what is natural selection??? http://mrhardy.wikispaces.com/Natural+Select ion.swf http://www.jesus-is-savior.com/Evolution%20Hoax/evolution_the_big_hoax.htm WRONG! There are many “details” or evidences! http://highered.mcgrawhill.com/sites/9834092339/stud ent_view0/chapter23/animation _-_phylogenetic_trees.html 5.4.2 Outline the evidence for evolution provided by the fossil record, selective breeding of domesticated animals and homologous structures. ANIMATION: http://www.pbs.org/wgbh/harvest/engineer/sele ct.html Can we see evolution today????? YES!!!! http://www.sumanasinc.com/sciencei nfocus/antibiotics/antibiotics_fla.html 5.4.8 Explain two examples of evolution in response to environmental change; one must be antibiotic resistance in bacteria. 5.4.8 Explain two examples of evolution in response to environmental change; one must be antibiotic resistance in bacteria. 5.4.8 Explain two examples of evolution in response to environmental change; one must be antibiotic resistance in bacteria.
