1. adaptive radiation in island chains (finches; honeycreepers)
2. exploiting a new niche in a common location
3. extrinsic factor prevents two or more groups from mating with
each other regularly
4. gene flow has been reduced between flies that feed on
different food varieties, even though they both live in the same
geographic area.
5. genetic polymorphism results in reproductive isolation
6. population isolated from another due to geographic barrier
7. populations remain in same physical area.
8. the gradual formation of the grand canyon split a population
into 2 divergent species.

The idea that all living things are made up of cells is considered scientific law. this means the idea is an emerging scientific idea that has a logical explanation. has been tested with similar results at least twice. is supported by scientific consensus and a large amount of evidence. has been rejected only once by the scientific community

Use this dichotomous key for insect identification to identify the insect shown. 1. a. insect has one pair of wings. order diptera b. insect has two pairs of wings. go to #2 2. a. front wings thicker in texture than hind wings go to #3. b. front and hind wings are same texture throughout. go to #4 3. a. front wings are short order dermaptera b. front wings cover entire abdomen order coleoptera 4. a. wings with scale on all parts of their area. order lepidoptera b. wings without scales go to #5. 5. a. hind wings smaller than front wings. order ephemeroptera b. front and hind wings nearly equal in size. order odonata the insect pictured is in the order diptera. ephemeroptera. coleoptera. odonata.
