True

In addition to their stocky bodies, which were adapted to conserve heat, Neandertals made clothes, developed elaborate tools, and hunted reindeer, mammoths, and woolly rhinos in order to adapt to the cold climate in Europe during the Würm glaciation.

The fossil evidence for the evolution of H. erectus out of australopithecine ancestors shows a number of major trends. One of the key trends is the development of a larger brain size in H. erectus compared to australopithecines. This suggests a shift towards more complex cognitive abilities and potentially a more varied and adaptable diet. Additionally, H. erectus fossils show evidence of a more modern body shape, with longer legs and a more efficient stride, indicating a shift towards a more terrestrial lifestyle.

These trends correlate with different uses of the environment. The larger brain size and more modern body shape of H. erectus likely allowed them to adapt to a wider range of environments and exploit a greater variety of resources. This may have enabled them to expand their range and colonize new habitats, including more open grassland areas. The shift towards a more terrestrial lifestyle also suggests a greater reliance on hunting and scavenging for food, as well as potentially using fire for cooking and protection.

Overall, the fossil evidence for the evolution of H. erectus out of australopithecine ancestors points to a significant shift in both physical and behavioral traits, allowing H. erectus to thrive in a wider range of environments and exploit new resources.

European fossils and tools have contributed disproportionately to our knowledge and interpretation of early (archaic) H. sapiens. What explains this?

One of the most surprising aspects of the recent discovery of H. floresiensis, a species of tiny people who lived, gathered, and hunted on the Indonesian island of Flores from about 95,000 B.P. until at least 13,000 B.P., is the specimens' very large skulls, yet they lack behaviors associated with anatomically modern humans.

Given the potential for language-based communications in activities such as cooperative hunting and the manufacture of complicated tools, and given brain size within the low H. sapiens range, it seems plausible to assume that A. boisei had rudimentary speech.

Scientists continue to debate the relationship between two Homo fossil finds: KNM-ER 1470, named H. rudolfensis by some, and KNM-ER 1813, generally considered to be an exemplar of H. habilis. Is the smaller KNM-ER 1813 a distinct species? Could it be a female version of KNM-ER 1470, both being simply a female and male pair of the highly variable H. habilis?
