Evolution: Key concepts
• History of evolutionary theories
• Darwin-Wallace model of natural selection
• Speciation, tectonics, + environmental pressure
• Evidence of evolution

Natural Selection• Darwin and Wallace
• Mutations neither inherently good nor bad
• Environment determines success
• Helps survival: passed on to offspring
• Hurts survival: more likely to die

Speciation• Population isolated
• Different conditions in each place = different selection
• Different adaptations to different environments
• Different enough = can’t interbreed = new species
