Evolution Flashcards
Competition for food, space
survival of the fittest
individual to survive and reproduce
fitness
inherited characteristics that increase an organisms to survive in a specific environment
adaptation
What is variation?
unique combination of inherited traits
What is evolution
the change in heritable traits of biological populations over successive generations
What is natural selection
individuals with traits that make them a better fit for their environment
darwins evidence
homo structures, georaphical distribution, embryology, fossil record
Vestigial structure
something coming from original ancestor that longer is in use of
Convergent evolution
different species evolve in similar adaptation
natural selection could not occur without
genetic variation in species
Homo structure
similar structure from common ancestor but different functions
what is the ORIGINAL cause of all variation?
mutation
