Common descent with modification
species undergo modifications through successive generations
species
- different kinds of organisms
- individuals of the same species share genetic similarity and can potentially interbreed
population
all individuals of the same species occupying a specific area over a particular time
fitness
measure of successful reproduction; leaving behind offspring/ genes
All species have descended from
other species/ common ancestor
Natural selection
the process through which a trait that confers reproductive advantage (greater fitness) to an individual spreads in a population over successive generations
biotic potential
most populations are capable of producing more offspring than can be supported by the environment
