The legs of a human and the limbs of a cat are similar in structure. these structures are called vestigial homologous analogous structures. this similarity indicates that evolved from cats cats evolved from the ancestors of humans cats and humans share a common ancestor . 1) a. vestigial b. homologous c. analogous 2) a. humans evolved from cats b. cats evolved from ancestors of humans c. cats and humans share a common ancestor.

The correct answers for your questions are B. homologous for the first question, the second questions answer is C. Cats and humans share a common ancestor.

let me know if its correct or wrong, however positive its correct.

The correct answers for the fill in the blanks are-

1) B) Homologous structures.

2)C). Cats and humans share a common ancestor.

Homologous structures/organs are those parts of two organisms that look similar in their form/structure because they share common ancestor (that is they have evolved from a common ancestor) but due to different adaptation, perform different function.

Example -The legs of a human and the limbs of a cat, which have evolved from a common ancestor.

The answer would be D)hormones
