Genetics and Evolution
concepts
evolution
one species
several species
natural selection
discovered by
Alfred Wallace
Charles Darwin
Origin of Species
Mutations
#
slow process
Population genetics
individual specie's genes
different alleles
diversity
gene pool
total alleles
changes gene pool
factors
accidents
organisms can't adapt
artificial selection
purposely changed alleles
natural selection
survival of fittest
more offspring produced
progeny must differ
nonfactors
natural selection
purpose
intention
planning
voluntary decision making
not functional
identical population
#
no competition
mutations
new/old alleles
multiple selection pressures
environmental factors
improve fitness
rates of evolution
quickly
structure
metabolism
complexity
slowly
loss of leaves
speciation
new species evolved
