A phylogenetic tree is a branching diagram showing evolutionary relationships among various living organisms based upon similarities and differences in their physical or genetic characteristics like the one above. In this case a human is more closely related to a mouse than a kangaroo, A platypus is more closely related to a kangaroo than a mouse, a human and a kangaroo share common features because of a common ancestor.
One species eventually changes into something completely different over the course of millions of years. This can be described using the evolution theory. The evolutionary process of species shows how one population of a species changes over time to the point where that population is distinct and can no longer interbreed with the parent population. Hence one species is changed into another over o period of time. Speciation is an evolutionary process by which a new species comes into being.
This theory of evolution was proposed by Charles Darwin.
This might be wrong but I think it’s 50%
Him having four other daughters shouldn’t play a roll in his fifth child gender. There’s a 50/50 chance he’ll have a boy or girl
Answer:
answer is chemical energy
Answer:
d. self-replicating RNA molecules
Explanation:
RNA molecules are single stranded, not included double stranded RNA structures from self folding, and DNA molecules are double stranded. It is thus believed that RNA molecules was the original genetic material and eventually DNA evolved from RNA and overtook RNA as the genetic material given DNA enhanced stability. Thus the answer has to be RNA.
