The embryological stages of _ show similarity in anatomical features.
Correct answer: C. All vertebrates
- A. All living things
- B. All non-vertebrates
- C. All vertebrates
- D. Human, jellyfish, and mouse
Explanation
The embryological stages of vertebrates show similarity in anatomical features.These shared embryonic features are homologous structures, meaning their underlying similarity is due to their derivation from a common ancestral structure. The genes and developmental pathways that control the early stages of vertebrate development are highly conserved (have remained largely unchanged) throughout evolutionary history.

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.
