The concept of ---- fitness, which accounts for the reproductive success of an organism's relatives, has profoundly reshaped our understanding of altruistic behaviour in social species.

Homologous structures in different species provide compelling evidence for common ----, as they share underlying anatomical patterns despite serving divergent functions.

When populations of the same species become geographically separated by a physical barrier such as a mountain range, ---- speciation may eventually occur as gene flow between them ceases entirely.

Genetic ---- refers to random changes in allele frequencies within a population, a process that is particularly influential in small populations where chance events can dramatically alter the gene pool.

The ---- organs found in certain species, such as the human appendix or the pelvic bones of whales, are evolutionary remnants that no longer serve their original function.
