Why do scientists consider vestigial structures (like a human appendix) evidence for evolution?

vestigial structures are considered evidence because scientists believe they are structures that were once used by a species ancestors but are not longer needed. these structures do not impair the organism in any way, so there is no need for evolution to get rid of them. for example, the human appendix is considered a vestigial structure.

Scientist believed that vestigial structures like the human appendix serves as evidence that evolution brings about new heritable traits over a long period of time in a population

Vestigial structures like the human appendix are referred to as homologous structures that are found in an organism with no well defined function.

Vestigial structures in one organism can be found functioning in another species of organism.

Consequently, scientist believed that vestigial structures like the human appendix serves as evidence that evolution brings about new heritable traits over a long period of time in a population.
