What molecular evidence supports the idea of natural selection?

Hope this helps!

Molecular evidence: similar proteins and genes found in closely related species, even if those genes are not used by an organism.

Good luck!

Did you know?

Did you know that molecular evidence strongly supports the concept of natural selection? By studying the genetic material, such as DNA and proteins, scientists can observe changes that occur over time within populations. These changes, known as mutations, provide a molecular record of evolution and are often the result of natural selection acting on the genetic variation within a population. By analyzing these molecular changes, scientists can trace the evolutionary history of species and gain insights into how natural selection has shaped the diversity of life on our planet. This molecular evidence not only strengthens the theory of natural selection but also allows scientists to better understand the mechanisms driving evolution.
