We can see some of the most important patterns Darwin noticed in distribution of organisms by looking at his observations of the Galápagos Islands off the coast of Ecuador. Darwin found that nearby islands in the Galápagos had similar but nonidentical species of finches living on them.
Answer:
E) horizontal gene transfer
Explanation:
Horizontal gene transfer can also be referred to as lateral gene transfer. It is the transmission of deoxyribonucleic acid (DNA) between different genomes.
Horizontal gene transfer has been shown to occur between different species, such as between prokaryotic and eukaryotic organisms.
Horizontal gene transfer is made possible by the existence of genetic elements, such as plasmids, transposons, and bacteriophages (bacteria that infects viruses).
