Strong evidence for evolution is found in gene comparisons using molecular biology and fossils. It has been proven that genetic changes are passed on from generation to generation, the new species gradually replacing the older ones. Vestigial features, or parts of the body that no longer perform their original use, are found in several species today. The DNA and gene differences are compared for many species. We even see evidence for this today through artificial selection, as farmers genetically modify livestock by getting two of them to interbreed. The DNA can be traced back to the original source.

At rest the lens of the eye will be more round when the ciliary muscles are contracted true or false
matrenka [14]

Answer:

True.

Explanation:

Yes, the lens of the eye will be more spherical when the ciliary muscles are contracted due to tension. When the relaxation occurs in the ciliary muscle , the zonular tension is increased, that causes the lens to be flatten and leads to decrease in optical power while on the other hand, when the ciliary muscle contracts, the tension in the equatorial zonular is increased which causes the central lens surface to become more rounded that leads to increases central optical power.
