How can the nonrecombining part of the Y chromosome (NRY) help researchers to trace the origins of modern humans? NRY enables researchers to identify the most recent common ancestor for the Y chromosome. NRY allows researchers to identify which species is immediately ancestral to modern humans. NRY can be used to identify "Eve." NRY can be used to distinguish the hominin lineage from the ape lineage.

NRY enables researchers to identify the most recent common ancestor for the Y chromosome.

Hominin remains have been found at sites throughout Africa, Europe, and Asia. Below are five of these fossil sites and their main finds. Place them in order from the oldest (earliest in fossil record = most ka) to the youngest (most recent in fossil record = least ka).

Ancient genomes indicate that early modern humans sometimes interbred with other hominins with whom they coexisted. Match the hominins that ancient humans interbred with to the locations where human ancestry indicates the greatest percentage of those particular nonhuman genes. (NOTE: Not all options may have a match.) Neanderthals australopithecines Homo erectus Denisovans

Which of the following is something that genetic data can tell researchers regarding the origin of modern humans? Select all that apply. Most of the genes that gave rise to modern humans evolved in Africa between 300 and 90 ka. Modern humans outside of Africa largely originated from a small African population that migrated approximately 60 ka. Interbreeding between early modern humans and the hominins in Eurasia occurred, but only on a small scale. Neanderthals did not interbreed with any other late hominin species in Eurasia.

Early modern humans interbred with other hominins, including Denisovans. True or False

True

Modern Homo sapiens fossils have less robust postcranial skeletons than Neanderthal skeletons.

True

Explain how genetic data allow us to reconstruct the expansion of modern humans out of Africa. Based on high-resolution analyses of the complete genomes of thousands of people from all over the world, we have been able to estimate the places and times where early human populations split, isolated reproductively, and developed identifiable genetic differences. According to these high-resolution analyses, where does the data suggest that the oldest human population splits occurred?

How did burial of the dead differ between Upper Paleolithic peoples and Neanderthals? Neanderthals were not known to intentionally bury their dead; modern humans were the first to do so. Neanderthals have evidence of multiple burials, while Upper Paleolithic peoples generally used only single burials. Upper Paleolithic burials were accompanied by ritual, whereas Neanderthal burials were not. Neanderthals were only buried with tools; Upper Paleolithic peoples were buried with tools in addition to other goods, such as ornaments.

Upper Paleolithic burials were accompanied by ritual, whereas Neanderthal burials were not.

Since 2000, the hypotheses that McBrearty and Brooks first presented about the Middle Stone Age (MSA) have been strengthened by archaeological evidence. According to this particular body of work, which of the following statements are true of MSA people? Their behavior was of comparable complexity to the behavior of Homo ergaster. They had symbolic behavior. They had large social networks. They did not exhibit complex adaptive technologies, such as the creation of bone tools, shelters, and hearths. They did not make use of personal adornment or decorations as later hominins did.

False

Why are humans less genetically variable than other organisms despite the fact that we range all over the world? Natural selection affects other species, but not humans. Humans are just more alike than other animals. The human species has undergone a rapid population expansion from a small population that had low levels of genetic diversity. Humans are better adapted to the tropics, so the genetic variability is not needed.
