An embryo of a turtle, mouse, and human show?
Correct answer: A. Comparative embroyology
- A. Comparative embroyology
- B. Distinct differences
- C. Vestigial organs
- D. Analogous structures
Explanation
Comparative embryology is the study of the similarities and differences in the embryos of different species to understand their evolutionary relationships and development. Key insights come from comparing embryonic structures like gill slits and tails, which show evidence of common ancestry, and studying developmental patterns to infer evolutionary history. This field has provided crucial support for evolutionary theory and helps researchers understand fundamental biological processes like gene regulation and morphogenesis.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
