Document Summary
Chapter 14 evolution: evolution by artificial selection, evolution by natural selection, where we are heading, the evolution of evolutionary thought, natural selection, evidence of evolution, evidence that populations evolve by natural selection. Scientific theory an explanation of important natural phenomena, developed through extensive, reproducible observations: evidence of evolution, fossils provide evidence of evolutionary change over time, comparative anatomy evidence of descent with modification, embryological similarity suggests common ancestry, biochemical and genetic analysis reveal relatedness among diverse groups. Biochemical similarities between all cells: dna is the genetic material, rna and ribosomes for protein synthesis, use most of the same 20 amino acids, use atp as a cellular energy carrier. Two important points underlie evolutionary changes: variations in population mutations (random) upon which natural selection works, are caused by, natural selection environment (not random) favors organisms that are best suited for a particular, a trait that is advantageous under one set of conditions may be disadvantageous under different conditions.
