What does the fossil record tell us about the evolution of the hominin skull? The face stuck out farther from the rest of the skull as hominins evolved? The part of the skull surrounding the brain could larger as hominins evolved? The face grew wider as hominins evolved? The part of the skull surrounding the brain grew more pointed as hominins evolved?
The fossil record provides valuable information about the evolution of the hominin skull, particularly in terms of its structural changes over time. However, it is important to note that these changes vary among different hominin species and may not be universal across the entire lineage.
Throughout hominin evolution, there is evidence that the face protruded less from the rest of the skull. Early hominin species, such as Australopithecus, exhibit more pronounced facial prognathism (where the face protrudes forward from the rest of the skull). In contrast, later hominin species, including erectus and Homo sapiens, show reduced facial prognathism, with the face being aligned more vertically with the rest of the skull.
Regarding the part of the skull surrounding the brain, there is evidence of that region becoming larger as hominins evolved. This enlargement is associated with an increase in brain size throughout the hominin lineage. Hominin species, such as Homo habilis and later erectus, exhibit larger cranial capacities compared to earlier species.
The fossil record also suggests that the face grew wider as hominins evolved. This widening is exemplified by the relatively broad and flat face observed in erectus and Homo sapiens compared to the narrower faces seen in more primitive hominin species.
However, the statement about the part of the skull surrounding the brain growing more pointed as hominins evolved is not supported by the fossil record. The shape of the cranial vault, which surrounds the brain, varies among different hominin species but does not show a consistent pattern of becoming more pointed over time.
