THE GENUS HOMO AND THE EMERGENCE OF US

What explains the emergence of archaic Homo?

• Evolutionary adaptations to changing environments.

• Increased brain size without environmental changes.

• Development of complex language skills.

• Migration to colder climates.

What tools and brain size did Homo habilis have?

• Homo habilis had advanced metal tools and a larger brain than Homo ergaster.

• Homo habilis had simple stone tools and a smaller brain compared to Homo ergaster and Homo erectus.

• Homo habilis had no tools and a brain size similar to modern humans.

• Homo habilis had wooden tools and a brain size larger than Homo erectus.

What is a key characteristic of Homo ergaster?

• Homo ergaster had a smaller brain than Homo habilis.

• Homo ergaster had a larger brain and more advanced tools compared to Homo habilis.

• Homo ergaster was the first species to use fire.

• Homo ergaster lived exclusively in trees.

Which species shows the largest brain volume?

• H. neanderthalensis/sapiens

• H. erectus

• Australopithecus afarensis

• Homo habilis

What distinguishes Homo erectus from earlier species?

• Homo erectus had a smaller brain than Homo habilis.

• Homo erectus had more advanced tools and a larger brain than both Homo habilis and Homo ergaster.

• Homo erectus was the first to use fire.

• Homo erectus lived exclusively in trees.

What role did interbreeding play in the evolution of Homo?

• It led to the extinction of Homo species.

• Interbreeding had no significant impact on evolution.

• Interbreeding with other species contributed to genetic diversity and adaptations.

• It caused Homo to become more isolated from other species.

What does the term 'Homo' describe?

• A genus that includes modern humans and their extinct relatives.

• A term used to describe all primates.

• A classification for all mammals.

• An umbrella category encompassing all Homo species.

How did migration impact the evolution of Homo species?

• Migration allowed Homo species to adapt to new environments and interact with other species.

• Migration caused Homo species to become extinct due to environmental challenges.

• Migration had no significant impact on the evolution of Homo species.

• Migration led to the development of advanced tools and technology among Homo species.

How did environmental changes influence Homo evolution?

• Environmental changes led to adaptations in behavior, diet, and tool use among Homo species.

• Environmental changes had no significant impact on Homo evolution.

• Homo species became extinct due to environmental changes.

• Environmental changes only affected the physical appearance of Homo species.

What is the significance of brain size in Homo species?

• Larger brain sizes are often associated with more complex behaviors and tool use.

• Smaller brain sizes indicate a more primitive species.

• Brain size has no correlation with behavior or tool use.

• All Homo species have the same brain size.
