Biology
1 answer:
ICE Princess25 [194]3 years ago
8 0

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.

Stolb23 [73]

The rocks and minerals in the Precambrian Earth were not weathering and eroding in the manner they are now. Instead they were kept compact for much longer periods, influencing the mixture of of different components with the water as well in meantime.
