Vidence of common descent<span> of </span>living organisms<span> has been discovered by scientists researching in a variety of disciplines over many decades, demonstrating the </span>common descent<span> of all </span>life on Earth<span> developing from a </span>last universal ancestor<span>. This evidence constructs the theoretical framework on which evolutionary theory rests, demonstrates that </span>evolution<span> does occur, and is able to show the natural processes that led to the emergence of Earth's </span>biodiversity<span>. Additionally, this evidence supports the </span>modern evolutionary synthesis<span>—the current </span>scientific theory<span> that explains how and why life changes over time. Evolutionary biologists document evidence of common descent by developing testable predictions, testing hypotheses, and constructing theories that illustrate and describe its causes.

Normal proteins allow the substances Na + and Cl- to move correctly through the cells of the skin, the pancreas and the lungs.
In contrast, the mutated proteins prevent them from moving through the cell, this causes mucus to accumulate in the skin, in the lungs and the pancreas, a medical condition called cystic fibrosis.
The most appropriate unit for describing a 26 mile marathon run would be C. Kilometre. As kilometres can be easily utilized and converted to miles and vice-versa.
For mutations to affect an organism's descendants, they must: 1) occur in cells that produce the next generation, and 2) affect the hereditary material. Ultimately, the interplay between inherited mutations and environmental pressures generates diversity among species.
