Adaptation & Change
All living things are different Diversity Many living things have similarities
All living things are “adapted” to their environment Adaptation: a trait or set of traits that improves
survival and reproduction

What similarities are obvious? How are they different? How is each adapted to its habitat?

Cumulative changes in characteristics of populations of organisms in successive generations This does not include individual change or
development
≠ Evolution

Evidence of Evolution
Rocks, fossils Comparative anatomy, embryology Geographic distribution Genetics Keep evidence and mechanisms of
evolution as separate thoughts…
