Answer:

Are usually present, but are no longer functional.

Explanation:

Vestigial structures are "evolutionary remnants". They are anatomical features that were once important throughout the organism's evolution, but now have no function. However, they aren't harmful either, so there has been no selective pressure for them to be removed via evolution.

Good examples in humans are the tail bone, wisdom teeth, and the appendix.

What ARE The relationship of genetics and environment in effecting evolutionary changes

Lubov Fominskaja [6]

The environment can influence the evolutionary changes so that the organism will be best suited to survive in that area. Genes that are useless in that specific environment will eventually be replaced with more useful traits as the species evolves.

Hope that helps
