Question

Homologoue structures referes to:

Structures that sound the same
Two organisms travel have about the same sized parts of their structure
Body parts that have the same function, but very different structures
Body parts of two different species that have similar structure and location in each species

Answer 1

Homologous structures refer to **body parts of two different species that have similar structure and location in each species**, even if they may serve different functions. This similarity indicates a common evolutionary ancestor. For example, the forelimbs of humans, whales, and bats have different functions (grasping, swimming, and flying, respectively) but share a similar underlying bone structure.
