"Homolog" Natural Recordings by Native Speakers
The word "homolog" refers to something that is similar or analogous in function or structure to another thing. In biology, homologous structures are parts of different organisms that have evolved from a common ancestor, but have been modified over time for different purposes. For example, the forelimbs of humans, birds, and whales are homologous because they all descended from a common limb-like structure in their ancient ancestors.
