Did homo erects have smaller brains than Australopithecus?
No, Homo erectus had larger brains than Australopithecus. Homo erectus had an average brain size of around 900 cubic centimeters, while Australopithecus had a brain size of around 400-500 cubic centimeters. This increase in brain size is thought to be one of the key factors in the evolution of Homo erectus.
How was homo erects different from homo habits?
Homo erectus had a more modern upright posture and larger brain size compared to Homo habilis. Homo erectus was also more advanced in tool-making and had a wider geographical distribution.
What are the differences between homo sapiens and homo erectus skull?
Homo sapiens have a larger brain size, higher forehead, reduced brow ridges, and a more rounded skull compared to Homo erectus. Homo erectus skulls typically have thicker cranial bones, a longer and lower skull shape, and prominent brow ridges.
Why does the cranium of australopithecus afarensis smaller than the cranium of homo erectus?
The smaller cranium of Australopithecus afarensis compared to Homo erectus may be due to differences in brain size and development. Australopithecus had a smaller brain capacity and may have had a less complex brain structure than Homo erectus. The differences in cranial size and shape could also be attributed to evolutionary adaptations and changes in diet, behavior, and habitat between the two species.
What features can be used to differentiate homo erictus from homo habilis?
Homo erectus has a larger brain size, more advanced technology such as hand axes, and a more upright posture compared to Homo habilis. Homo erectus also had a wider geographic range and evidence of controlled use of fire.

What is the homo erectus brain size?
About 3/4ths of a modern human.

What was it about homo erectus that allowed him to leave Africa and migrate to Europe and Java and China?

Are homo habilis more like homo erectus or more like the australopithecines?
Homo habilis is more like Homo erectus than the australopithecines. Homo habilis is considered part of the genus Homo due to its more advanced traits such as increased brain size and tool use, while australopithecines are an earlier group of hominins with more primitive features.
What are two behavloral advances that distinguished homo erectus from H habilis?
Homo erectus had a larger brain size and more advanced tool-making abilities compared to Homo habilis, indicating a shift towards more complex thinking and problem-solving. Additionally, Homo erectus were the first hominins to migrate out of Africa, showing increased adaptability and capability for long-distance travel.
What is the plural form of Homo habilis Homo erectus and Homo sapiens?
The plural form of Homo habilis is Homo habilis, the plural form of Homo erectus is Homo erectus, and the plural form of Homo sapiens is Homo sapiens.
What adaptations did Homo Erectus have?
Homo erectus had adaptations such as a more efficient bipedal walk, reduced jaw and tooth size, increased brain size, and the ability to use tools for hunting and scavenging. These adaptations helped them to better navigate and survive in various environments, leading to their widespread distribution across Africa and Eurasia.
What is the cranial breadth of a homo erectus?
The cranial breadth of Homo erectus varies between individuals but typically ranges between 130-160mm. This measurement helps in understanding the size and shape of the Homo erectus skull, which is a key aspect in studying human evolution.
