Most people agree that goldfish are an example of fish, and coelacanths are also an example of fish. But we humans (in fact all tetrapods–amphibians, reptiles, and mammals) shared a common ancestor with coelacanths more recently than either us or coelacanths shared a common ancestor with goldfish!

An order is a group of similar families. A class is a group of similar orders. A phylum is a group of similar classes. A kingdom is a group of similar phyla.

1. Domain. Info: Domain is the largest taxa, and there are only three domains: Archaea, Bacteria, and Eukarya. As a rule of thumb the less number of members a taxa has, the broader spectrum of organisms it carries.

As for the chimps, just because they stayed in the trees doesn’t mean they stopped evolving. A genetic analysis published in 2010 suggests that their ancestors split from ancestral bonobos 930,000 years ago, and that the ancestors of three living subspecies diverged 460,000 years ago.

Evolution of Other Vertebrate Classes Amphibians, reptiles, mammals, and birds evolved after fish. The first amphibians evolved from a lobe-finned fish ancestor about 365 million years ago. Mammals and birds both evolved from reptile-like ancestors.

Thus, the most appropriate answer is D, that is the correct order for human evolution is Australopithecus, Homo erectus, Neanderthal man, Cro-magnon man, Homo sapiens.

Since the extinction event that wiped out the dinosaurs 66 million years ago, fish have evolved and diversified, leading to the wide variety of fish species we see today. According to a new study, many of today’s fish lineages emerged right around this time. …

Modern birds descended from a group of two-legged dinosaurs known as theropods, whose members include the towering Tyrannosaurus rex and the smaller velociraptors.
