Question

The embryos of a fish, chicken and rabbit all contain a tail and pharyngeal pouches at some point during their early development. Although the fetus of all these species looks different from one another, the similiarity between these organisms during their embryological development suggests an evolutionary relationship among all _________________________ species.

Answer 1

Homologous Species

Step-by-step explanation:

Homologous species are those which have origin from different species but have some body part or organs which have similarity in structure or functions. Like in this case the embryo of fish, chicken and rabbit have tail and pharyngeal pouches which shows that they all share a common ancestory as they have similar structure during their early stage of development.

Answer 2

Homologous species

These species are considered homologous as these originated from the same ancestors and thus share some common physical traits.
