5. The CNTNAP2 gene explains humans’ unique capacity for symbolic language.
1.False
Explanation: Humans evolved from one branch of the great apes, but whether it was gorillas or chimpanzees was not clear until genetic research revealed that humans are more closely related to chimpanzees; 98.5 percent of our genes are the same as those of chimpanzees, making them our closest relatives.
2.True
Explanation: We use the term hominine to name all the species on the branch, including humans, since the split from a common ancestor with chimpanzees.
3.True
Explanation: Species called Homo are characterized by tool use, independence from trees, and rapid brain growth, from the volume of an apple to that of a full grapefruit in the next million years.
4.FAlse
Explanation: With the emergence of agriculture, human communities grew in size and complexity; so did the amount of energy and resources they used; and so did the total number of humans.
5.False
Explanation: Few would argue that the FOXP2 gene is enough to explain our unique capacity for symbolic language, particularly as there is evidence that Neandertals shared the same form of the FOXP2 gene as humans.
