The Ultimate Human Evolution Quiz! Trivia

Explanation
Even the earliest humans already had non-grasping big toes.

Explanation
Multiregional model = H. sapiens evolving in multiple areas with gene flow between populations Out of Africa = all H. sapiens have 'recent' African ancestors in common (and H. erectus in other area died out)

Explanation
Dinosaurs died out long before the human family tree split off from our common ancestor with lesser apes. Some primitive types of mammal did coexist with dinosaurs, one of these was the ancestor of all currently living mammals, including humans.

Explanation
The foramen magnum in Homo erectus is located directly under the skull, not at an angle on the back of the skull. This is an important anatomical feature as it indicates the position of the spinal cord and the attachment of the skull to the vertebral column. The position of the foramen magnum directly under the skull suggests an upright posture and bipedal locomotion, which are characteristic features of Homo erectus.

Explanation
H. sapiens migrating to New Zealand or Pacific islands would have had to use walking + sea vessel (canoes, rafts, etc) at some point because these islands are separated by large bodies of water. Walking alone would not have been sufficient to reach these islands, so they would have needed some form of watercraft to navigate the sea and reach their destination.

Explanation
The explanation for the given answer being true is that the controlled use of fire by humans allowed them to consume a wider variety of foods, as some foods would have been indigestible without cooking. Additionally, cooking made food easier to digest, enabling humans to extract more kilojoules from their food. Therefore, the statement accurately reflects the benefits of the controlled use of fire in relation to human diet and nutrition.

Explanation
Using fire to cook food, bipedalism in a grassland habitat, and building shelters to keep warm all saved humans energy. By using fire to cook food, humans were able to break down food more easily and obtain more nutrients, resulting in increased energy for reproduction. Bipedalism in a grassland habitat allowed humans to efficiently travel long distances, hunt, and gather food, again contributing to an increase in energy available for reproduction. Building shelters to keep warm protected humans from harsh weather conditions, allowing them to conserve energy that would have been otherwise used to regulate body temperature, and redirecting it towards reproduction.
