The similarities, well... it would be the fact that.....they are the same thing.
Species, because from D, K, P, C, O, F, G, S in the Taxonomic Rank, species is the most specific.
Answer:
The theory of common descent states that all living organisms are descendants of a single ancestor. Hence, common descent helps scientists better understand why species living in different geographical regions exhibit different traits. Some of these traits are highly conserved among broad animal classifications (e.g., vertebrates or tetrapods), and seemingly different species (e.g., birds and reptiles) share inherited physical and genetic traits, and successfully adapted organisms typically produce more offspring.
Explanation:
In evolutionary biology, it is theorized that a group of organisms share common descent if they have a common ancestor.
Answer:
Continental drift was a theory that explained how continents shift position on Earth's surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.
