Document Summary

Natural selection: variation among individuals, much of this variation is inherited, more individuals are produced than can survive. Heritable traits that increase probability of survival/reproduction will become more widespread. Black (melanic) form <1% of population; very rare. With coal burning, air population become bad. Variation that leads to differential survival or reproduction is inherited. You have just witnessed evolution by natural selection. Fossil record (compare fossil records of species to see the progression of natural selection) Universal genetic code for proteins (we all share similar genetic code) By 1980s, hundreds of direct measurements by researchers of natural selection in the wild (natural selection) principle mechanism of evolution. Darwin"s finches: a case study: all the diverse species of finches all evolved from one common ancestor in south america, a population of the ancestor bird probably became isolated to the. Galapagos islands and diverse species evolved through natural selection: all the beaks of these different finches have adapted to their environment.
