GEOG 1400 Lecture Notes - Lecture 32: Allopatric Speciation, Adaptive Radiation, Argyroxiphium
Document Summary
Individuals express genetic traits: variability in all populations, not as viable in a group than individually, most successful traits we have we pass on to the next generations, selective process. Traits normally are genetically driven we give to our kids part of our genetics. Individuals do not evolve, genes do not change: evolution occurs at the ____ in the environment, adapting to the negative thing by producing more children that are more, some heritable traits provide competitive advantage. Increased reproduction: pass traits to offspring, more offspring carry bene cial traits capable of surviving. The peppered moth: biston betularia, britain, bird predators, dark form observed. Lichen-covered (plant like thing that lives on trees) surfaces camou age according to the tree. Industrial areas: poor camou age: light coloured forms eaten more by birds, dark form observed, adaptation to pollution, the peppered moth.
