Process of Evolution
variation
homologous structures appear in separate lineages dues to common ancestor
analogous structures are parts that look alike but evolved after lineages diverged
morphological divergence is a change from the body form or original ancestor
morphological convergence is evolution of similar parts in different lineages
natural selection
survival of the fittest
fitness is measured by an individuals genetic contribution to future generations
adaptive traits enhance fitness
members of populations compete for limited resources
inheritance
all life originated from a common ancestor
drifting continents is probably why animals can be found in remote locations
Pangea was the original supercontinent
continents are made up of plate tectonics that gradually shift over time
time
fossil records
half life is time it takes radioisotopes to decay
radiometric dating is used to measure age of a material
