Which of the following is not an adaptive pattern of early African hominins?
Group of answer choices
Speciation was occurring quite frequently.
Early hominin species had restricted ranges, thus it is likely they each exploited a small area allowing for rapid genetic diversification through genetic drift and natural selection and speciation.
Most of the species appear to have been tied to desert-arid habitats.
With the exception of early Homo, there are few evolutionary trends regarding increases in body size or encephalization.
All of the early hominins show an ape-like developmental pattern.

- What can we say about Homo sapiens? Select one: O a. Originated in Africa, shared a common ancestor with Neanderthals, Denisovans, and most likely descendants from a group related to Homo heildenbergensis O b. Migrated out of Africa, most likely 2 million years ago, hybridized with Homo floresiensis and differentiated from other Homo as the sole species to evolved language. O c. Migrated from Ethiopia 200,000 years ago, hybridized with Denisovans and Neanderthals to later replace them O d. Is the result of hybridization between Neanderthals and Denisovans, only lineage to show bipedalism and posses the largest brain capacity of all Homo O e.
