You come across a website that states homo rudolfensis was a slightly larger version of homo erectus found in canada in the eighteenth century. based on your knowledge of physical anthropology, though, you know that this website is bunk because: 1. homo rudolfensis and homo habilis are the same species.2. only homo sapiens reached north america.3. fossil hominids were not found until the nineteenth century.4. all of the above

The answer is 4- All of the above.

Explanation:

The numbers 1-3 are wrong because;

1- Homo rudolfensis and Homo habilis are not the same due to the fact that they both posses different characters. For example, Homo Rudolfensis was discovered having a larger brain size compared to Homo Habilis which is smaller, the teeth of Homo Rudolfensis are not preserved, they have square upper jaw, slightly developed brow ridge, they have a larger face which is also flat and longer. However, the Homo Habilis have small upper jaw with human like teeth, round upper jaw, strongly developed ridge brow and a small face which is not very flat.

2- Records show that Homo Erectus also dispersed into North America.

3 Fossil hominids have been dated to have existed about 7-8 million years ago

structure is maintained and sustained by:

-cytoskeleton: gives cells coherence

-cell wall: support

-cytoplasm: shape

hope this .
