How does molecular biology prove evolution?

Answer 1

ERV stands for endogenous retroviral insertion. These are introns, genetic sequences that do not express proteins. In addition, viral insertions are foreign, they are not part of the original host organism. When we find common ERVs in the DNA of Humans and other primates, the only reasonable explanation is that these species share common ancestry. It would be extremely unlikely the same ransom code would just happen to infect unrelated species in the same location of a chromosome. Mitochondrial DNA are another example. The Mt DNA of humans and chimps are very similar. Yet we have grown rabbits with cow Mt DNA. There is no reason mitochondria, which are organelles with their own DNA passed down through the maternal line (sperm Mt DNA are jettisoned), must be similar, as cow and rabbit experiments show. Yet the more closely animals are related, the closer their Mt DNA align. Shared ancestry beautifully explains this result. Were all species created simultaneously, we would expect the Mt DNA to all be identical, or equally varied across species which cannot interbreed. We would NOT expect the Mt DNA to align with evolutionary pathways unless evolution was accurate. It does not support evolution. It is actually DISPROVING it.

"As the number of unexplained, irreducibly complex biological systems increases, our confidence that Darwin's criterion of failure has been met skyrockets toward the maximum that science allows." (Darwin's Black Box---The Biochemical Challenge to Evolution, Michael J. Behe, pages 39-40) If you didn't quite get that, it basically means that recent findings in the field of molecular biology raise serious doubts about the truth behind Darwin's theory.

Answer 2

Supports evolution. When we see a mitochondria in most eukaryote cells we see common ancestry. We see highly conserved biochemical pathways in cells across many taxa as evidence for common ancestry. We can see precursors to cellular machinery is less complicated cells showing the work of natural selection. This explanation fits the facts while other explanation fail miserably.

Answer 3

Molecular Biology supports evolution by showing that all living organisms share similar genetic material, such as DNA and proteins. By analyzing molecular data, scientists can track the changes in genes and proteins over time, which provide evidence for common ancestry among different species and the gradual changes that have occurred through evolution.
