BIOL 1011 Lecture : Lecture25
Document Summary
Comparison among human, cat, whale, and bat arm bones. Similar environmental forces select for similar structures in unrelated organisms. Develop in their own lineage as they evolve: developmental biology. Rudimentary form of an organ more fully formed in ancestor. Ex: appendix, wisdom teeth, thirteenth rib, fifth toe. Evolutionary baggage : biochemical and genetic analyses, common use and similarities of dna, rna, amino acids, ribosomes, genetic codes, Atp, electron carriers, electron transport systems, etc: correlation of dna, proteins, etc with relatedness of species, artificial selection. The unequal survival and reproduction of organisms due to environmental forces resulting in the preservation of favorable adaptations. Processes of natural selection selects from what is available in the gene pool (population) New genes are not created on demand. Males fighting for the right to mate with the females. Transformation of plants to make resistant to insects (know the steps) What is life, prokaryote, eukaryote, atp, the differences between mitosis and meiosis,
