Adaptive radiation of human species, followed by extinction of most of these species

there are many missing links, thus no good fossil record of human evolution

Answer 1

1.
There are many missing links regarding human evolution, thus, there is no good fossil record of human evolution.
Hence, second option is the correct answer.
2.
Due to the invasion of humans, there has been extinction of large number of different species of Organisms from different parts of the world. The parts of the world, where large amount of extinction of species has taken place include, Africa, Asia, Europe, Australia, North America and South America.
Eurasia has experienced the lowest amount of extinction following humans expanding into (across) it.
Hence, second option is the correct answer.
3.
Hominids include chimpanzee, Gorilla, Orangutan, Humans that belong to the family, Hominidae.
Human is an animal. Hominids include Hominids, So, Humans are hominins. Since, all cells of human body contain defined nucleus, humans are Eukaryotes.
Anthropoids include, new world monkeys and old world monkeys and humans. So humans also are anthropoids.
Primates include lemurs, monkeys, and apes, with the latter category including humans. So, humans also are primates.
In the starting of human evolution, humans also have four legs, later they started walking on two legs. So humans also are tetrapods.
Humans belong to the class Mammalia, which belongs to the subphylum vertebrata, this belongs to the main phylum Chordata.
Humans are omniotes, since omnion is one of the embryonic sacs in human embryonic development.
