There have been several mass extinction…mes (67)in hive-196037 • 3 months agoEvolutionary Biology: Speciation, Reproductive Isolation, and HybridsIn this video, I explain speciation, the process by which one lineage splits into two independent lineages that evolve separately. For speciation to occur, reproductive isolation is required, which…mes (67)in hive-196037 • 3 months agoEvolutionary Biology: Phylogenies, Homology, and TaxonomyIn this video I go over phylogenies, which represent the evolutionary history of a group of organisms or their genes. Phylogenetic trees are used to compare and group different species. All living…
