Question

Watch this video about natural selection and plate tectonics. The movement of the plates can contribute to the natural selection of organisms. What is another natural process that could contribute to the evolution of a species’ genomes? How would this process affect evolution?

Answer 1

Explanation:

Processes such as mutations, duplications, exon shuffling, transposable elements and pseudogenes have contributed to genomic evolution.

Answer 2

Answer:

A natural disaster, such as an earthquake or a volcanic eruption, could affect the evolution of a species’ genome. These disasters could kill a large number of organisms at once, decreasing the genetic variation in the gene pool. In some cases, large populations may become separated, which can lead to several smaller populations evolving in different ways.
