Patterns of Evolution

Forming of a new species by evolution from a pre existing species - Some sort of isolation must occur - they are 2 different species when no longer able to reproduce

A group of organisms that can successfully inherdted(help me with this word i can’t read my handwriting) and produce viable offspring

Elimination of a species

Occurs at a slow rate (ex changes in climate)

Occurs when a catastrophic event changes the environment suddenly ex volcano, meteor, tsunami

Slow, constant changes over a long period of time ex gradual evolution of peppered moths becoming darker over time after the industrial revolution

Bursts of change followed by periods of stability.

A number of different species arise from one common ancestor - new environments caused differences to evolve

When unrelated species evolve similar characteristics because they live in similar environments

Occurs when two populations of organisms from a specialized relationship and thus change in response to each other ex flowers and the insects that pollinate them

A type of divergent evolution occuring on a small scale over a short period of time
