QuestionAncestors of monkeys, apes, and humans lived how long ago?Answer Choices•100 million years ago•50 million years ago•70 million years agoCorrect Answer50million years agoWhy This Is CorrectEarly primates—ancestors of modern monkeys, apes, and humans—first appeared during the earlyCenozoic Era, about50 million years ago. This period marked major diversification amongmammals following the extinction of dinosaurs.2. QuestionThe first hominids belonged to what group?Answer Choices•Australopithecus•Homo erectus•Homo habilis

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?

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.

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. Question“Lucy” was a member of which group?Answer Choices•Australopithecus•Homo erectus•Homo habilisCorrect AnswerAustralopithecusWhy This IsCorrect

Shelived about 3.2 million years ago and showed clear evidence ofbipedal walking, a key trait of earlyhuman ancestors.8. QuestionMembers ofwhich group were the predominant species during the Stone Age?Answer Choices•Australopithecus•Homo erectus•Homo habilisCorrect AnswerHomo erectusWhy This Is CorrectHomo erectuswere the predominant human species during much of theStone Age, especially theearly (Paleolithic) period. They used more advanced stone tools, controlled fire, hunted cooperatively,and spread across Africa, Asia, and Europe, making them the most widespread and dominanthominids of that time.9. QuestionMembers of which group were presumed to be the first fire users?Answer Choices•Australopithecus•Homo erectus•Homo habilis
