- 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.arrow_forwardThe Vendija rockshelter and Krapina cave in Croatia contained ... evidence that both Neanderthals and Modern Humans occupied them. evidence that dinosaurs ate Neanderthals. elaborately ornamented modern human burials. fossils of Homo erectus. evidence that Aliens interbred with Neanderthals.arrow_forwardCompare and contrast hominin evolution through the years using the following criteria: Species Social and cultural behaviour Anatomy (ex. skull) Habitatarrow_forward
- 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. A and C are correctarrow_forwardDescribe some of the key characteristics of Homo habilis - the first species in our genus "homo". What traits set this species apart from earlier hominins? e.g. Brain size? What kind of tools did they make? when did they live? diet? etc. Include a personal reflection on what stood out to you about Homo habilis.arrow_forwardA biologist is trying to infer how five closely related species of snakes are related to one another. She notices that some of the snakes have forked tongues and others do not. Which of the following would help her distinguish the ancestral state? Group of answer choices She looks at a representative mammal species to see if it has a forked tongue. She locates a specimen of a more closely related snake to see if it has forked tongue. She looks among snakes fossils for evidence that being forked is a characteristic of the ancestor of this group, but determines no such fossil exist. She flips a coin.arrow_forward
