Evolution Flashcards
Unrealated organisms in a similar enviorment evolve to have similar characteristics
Convergent
Closely related organisms have different characteristscs
(common ancestor)
Divergent
Species evolve “together” when closely related in nature
Coevolution
hummingbird and flower evolve, and both benefit each other
coevolution
dog species evolved from common ancestor
divergent

convergent
Characteristic that increases an organisms chance of serveing
Adaptation
Organisms most suited for their enviorment survive
Natural Selection
Evolution
Change over time
Selective Pressures
External agents that affect an organsms ability to survive
Mutation
Change in the genetic material of a cell
Gene Flow
The movement of genes in a population
Allele
A form of a gene
Fitness
How well an organism can survive in its enviorment
Allele Frequency
