This period marked major diversification amongmammals following the extinction of dinosaurs.2.

Study GuideCorrect AnswerAustralopithecusWhy This Is CorrectThe earliest known hominids are classified in the genusAustralopithecus. These species lived inAfrica several million years ago and showed early traits of bipedalism, which distinguishes hominidsfrom other primates.Homo habilisandHomo erectusappeared later in human evolution.3. QuestionMembers of which groupwere regarded as the first humans?Answer Choices•Australopithecus•Homo erectus•Homo habilisCorrect AnswerHomo habilisWhy This Is CorrectHomo habilisis regarded as the first human species because its members showed clear human-liketraits, especially theuse of toolsand a larger brain size than earlier hominids. WhileAustralopithecuswere earlier ancestors,Homo habilismarks the beginning of the human genus(Homo).4. QuestionMembers of which group were skillful at hunting and butchering animals?

Study GuideAnswer Choices•Australopithecus•Homo erectus•Homo habilisCorrect AnswerHomo erectusWhy This Is CorrectHomo erectuswere skilled hunters and were known forbutchering animals, using more advancedtools, and controlling fire. These abilities allowed them to hunt large animals and survive in a widerrange of environments than earlier hominids likeAustralopithecusandHomo habilis.5. QuestionMembers of which group were characterized by heavy jaws, low foreheads, and small braincapacities?Answer Choices•Australopithecus•Homo erectus•Homo habilisCorrect AnswerAustralopithecusWhy This Is CorrectAustralopithecusspecies hadheavy jaws,low-sloping foreheads, andsmall brain sizescompared to later human ancestors. These traits reflect their early position in human evolution. Incontrast,Homo habilisandHomo erectushad larger brains and more human-like skull features.

Study Guide6. QuestionMembers of which group were the first to use language?Answer Choices•Australopithecus•Homo erectus•Homo habilisCorrect AnswerHomo erectusWhy This Is CorrectHomo erectusis considered the first hominid group likely capable ofearly language or complexvocal communication. Their larger brain size, social cooperation (especially in hunting), andanatomical changes related to speech suggest the beginnings of spoken language. Earlier groups likeAustralopithecusandHomo habilislacked these advanced features.7.
