Evolution Crossword

3. Speciation that occurs when populations of the same species become geographically isolated from each other, leading to reproductive isolation and the eventual divergence into separate species.
7. A species of moth (Biston betularia) whose populations in industrialized areas experienced evolutionary changes in coloration due to natural selection driven by pollution-induced changes in tree bark color.
8. The process by which two or more related species become more dissimilar over time, often due to different environmental pressures or selective forces.
9. The ability of certain organisms to survive exposure to the pesticide DDT due to genetic variations that confer resistance to its effects.
10. Referring to a species that is found only in a specific geographic area and nowhere else in the world.

1. The process by which individuals with favorable traits are more likely to survive and reproduce, leading to the increase in frequency of those traits in a population over time.
2. In phylogenetic analysis, a species or group of species that is closely related to but outside the group of interest, used to determine the ancestral state of characters and to root the tree
4. A type of natural selection in which individuals with phenotypes at one extreme of the range of variation in a population have higher fitness, leading to a shift in the population's phenotype distribution over time.
5. The evolutionary process by which new species arise from a single ancestral species, typically through the development of reproductive isolation between populations.
6. The ability of an organism to survive and reproduce in its environment, often measured by the number of offspring produced that survive to reproduce themselves.
