Natural Selection
Across
- 6. process by which animals who are more "fit" will reproduce and pass on more genetic material.
- 7. the number of alleles available in a population.
Down
- 1. the development of a new species from a previously existing species.
- 2. a remnant from a body structure that has lost use, but is still present in an organism.
- 3. structures that have the same function, but are not from a common ancestor.
- 4. traits being passed down from parents to offspring.
- 5. structures that have the same structure, given by a common ancestor.
