Students have asked these similar questions
The first modern humans evolved in Africa.
a) What are two kinds of evidence supporting that conclusion, one based on data from living individuals and one from some other source of data?
b) What are some unique anatomic and behavioral traits that are unique to hominid species compared to primates, and to Homo sapiens in particular, compared to other hominid species?
There are two hypotheses to explain the pattern of Human Evolution:
1) Progressive Evolution of a Single Lineage ; 2) Evolutionary Radiation
Which of these hypotheses are supported by evidence, and briefly explain why?
Please explain in details
What do the multiregional and out-of-Africa hypotheses predict about the age of the common ancestor of all humans living today?

A.Woolly mammoths expanded into the territories that Denisovans lived, and used up the food and land resources in that area. B.Homo sapiens expanded into the territories that Denisovans lived, and used up the food and land resources in that area. C.Homo sapiens expanded into the territories that Denisovans lived, and killed off the Denisovans. D.Predators expanded into the territories that Denisovans lived, and they killed off the Denisovans.arrow_forwardEvolution in Humans 1) explain how fossil evidence is used to reconstruct the hominid history 2) explain how genetic evidence is used to document changes in species and populations over time 3) describe several techniques that paleontologists today use to establish fossil agearrow_forwardWhat two pieces of evidence support the claim that all life on Earth descended from a common ancestor?arrow_forward

- What does it mean then to say that humans evolved from apes?arrow_forward1) Does the fossil record indicate that life first appeared in the water or on the land? WATER or LAND 2) Does the fossil record indicate that invertebrates (trilobites) and vertebrates (fish) evolved during the same geological period? YES or NO 3) Does the fossil record indicate that birds evolved from mammals or reptiles? MAMMALS or REPTILES 4) The fossil record indicates that hominids evolved from an ancestral hominoid approximately? 4-5 million years ago or 1-2 million years ago What kinds of organisms appear earliest in the fossil record? PROKARYOTES or EUKARYOTESarrow_forwardWhich of the following statements about convergent evolution is true? (a) It demonstrates how similar environments can lead to different physical structures. (b) It demonstrates how similar environments can lead to the same physical structures. (c) It demonstrates that similarity of structures is due to descent from a common ancestor. (d) It demonstrates that similarity of structures is due to random chance.arrow_forward
- How does finding the same fossils of a land animal on two different continents support the hypothesis of continental drift? A) The land animal fossil is now found in colder parts of the world which means the continents had drifted since the fossils were made. B) The land animal fossil could only have ended up fossilized on both continents if they were once together C) The land animal fossil was unable to swim across oceans so the fact that its fossils were found on distant continents suggested those continents had once been fused together as later moved apart. D) The land animal fossil wasnt found in Asia which wegner thought was only stable continent that hadn’t moved.arrow_forwardWe have studied how the six major primate groups evolved, with the most recent group being the hominins.The hominins branched off from main ape group around 7 million years ago.According to our lessons explain your reasoning as to whether there is a missing link,or one single specimen that embodies both ape and hominin traits, that serves as a transition between what is clearly ape and what is clearly hominin?What have you found most interesting about the beginning of hominin evolution and why?arrow_forwardIn 1822, an Arkansas farmer discovered a fossil when a hill collapsed on his property. The farmer sent the bones to the Philadelphia society to be reviewed by scientists where it was determined that the bones were from a whale. Through research, the scientists discovered whales have a vestigial structure that includes a pelvic girdle and hind limbs. Which evidence best supports the theory that organisms, such as whales, have common ancestry and have evolved? Select all that apply. Group of answer choices A/Ostriches and emus are flightless birds. B/Ancient cave paintings depict humans and bulls thousands of years ago. C/More than 96% of human DNA is identical to chimpanzee DNA. D/In the early stages of embryonic development, humans, rabbits, fish, and salamanders look very similar. E/Scientists discovered eight genetic variants in four regions of the human genome that influence skin color ranging from very light to very dark.arrow_forward
