Multiple Choice

Why was having a larger brain advantageous for early hominins?

It allowed for more complex social interactions and problem-solving abilities.

It provided better thermoregulation in varying climates.

It increased their ability to digest a wider variety of foods.

It enabled early hominins to run faster and escape predators more effectively.

Verified step by step guidance

Consider the role of brain size in social interactions: A larger brain can support more complex social structures and communication, which are crucial for survival and cooperation in groups.

Evaluate the impact of brain size on problem-solving: A larger brain allows for advanced cognitive functions, enabling early hominins to develop tools and strategies for survival.

Analyze the relationship between brain size and thermoregulation: While brain size can influence body heat production, it is not the primary factor in thermoregulation compared to other physiological adaptations.

Examine the connection between brain size and diet: A larger brain may support the development of strategies to access and process a wider variety of foods, but it is not directly related to digestive capabilities.

Assess the influence of brain size on physical abilities: While cognitive abilities can aid in planning and avoiding predators, brain size does not directly enhance physical speed or agility.
