1.
The fossil record provides
direct evidence for the evolution of
life on earth. |
|
|
2.
Evolution occurs in populations of interbreeding organisms. |
|
|
3.
A molecular analysis of the genomes (genetic
material) of organisms provides evidence for the evolutionary
relationships between organisms. |
|
|
4.
The establishment of barriers to interbreeding can produce
a selective advantage by preserving adaptations. |
|
|
5. Speciation occurs
when members of two populations can no longer interbreed
successfully. |
|
|
6.
Evolution is based on genetic variation and superfecundity,
which leads to changes in genetic composition over time. |
|
|
7.
WIthout mutations there
would be no evolution. |
|
|
8.
Random events, such as genetic
drift, founder
effects and genetic
bottlenecks, can influence evolutionary
change. |
|
|
9.
Non-random mating behavior, known as sexual
selection, can influence evolutionary
change. |
