Evolution

are similar in appearance but different in anatomy, but perform the same function (bird wing vs. butterfly wing)

• vestigial structures
• artifical selection
• homologous structures
• analogous structures

when individuals near the center of the curve have higher fitness than individuals at either end. ie short tails mess up a cat's balance; long tails drag on the ground; medium tails are the best. (stabilizing is middle)

• directional selection
• artifical selection
• disruptive selection
• stabillizing selection

are similar structures that evolved from a common ancestor, but have different functions. ( wings of a bat and arms of a primate

• vestigial structures
• analogous structures
• bottleneck effect
• homologous structures

change in allele, different version of a gene, frequencies as a result of the migration of a small subgroup of a population

NGSS.HS-LS4-4

A change in allele frequency following a dramatic reduction in the size of a population

• bottleneck effect
• Fitness
• founder effect
• convergent evolution

when two closely related species develop different traits based on different environmental pressures

• Coevolution
• divergent evolution
• directional selection
• convergent evolution

NGSS.HS-LS4-5

When unrelated species evolve similar traits even though they live in different parts of the world

• convergent evolution
• founder effect
• Coevolution
• divergent evolution

NGSS.MS-LS4-2

When two species develop a close relationship and the evolution of one of the species develops the evolution of the other. examples are parasite and host, prey and predator, or follower and pollinator.

• convergent evolution
• Coevolution
• divergent evolution
