Question

name 2 vestigial structures

Answer 1

read this Humans cannot manufacture their own vitamin C, most other mammals can because they possess a gene enabling them to produce an enzyme (L-gulono-gamma-lactone oxidase) which in turn makes it possible for them to produce vitamin C. Humans possess a defective copy of this gene that does not produce the required enzyme (or any other product). This gene was presumably disabled by mutation at a time in primate evolution when its loss was not a significant disadvantage, and now remains as a vestigial genetic sequence.
