Document Summary

Variability in structure, physiology and behaviour are associated with higher survival rates and reproduction of genes into next generation (natural selection leads to evolution) Leclerc: environment acts directly on genes through organic particles. Lamark: conscious will, use and disuse leads to change; characteristics are inheritable, preordained to perfection, environment has effects on organ development. Alfred russell wallace had similar ideas to darwin co-wrote paper year before origin of species. Neodarwinism: natural selection + genetics, fitness (ability to contribute genes to next generation either directly or indirectly) Spandrels: evolutionary byproducts, used to have function in survival (belly buttons) Exaptations: things that have a different function than what they were originally evolved for (feathers warmth flight) Noise: 2 parts that have same function, both evolutionarily functional therefore both continue to exist in population. Big brain, great variability, cerebrum and brain stem are common among most animals. Increased in size over evolution (mostly in cerebrum), more convolutions.
