  3. The edaphon its made up of thousands of organisms including a huge number of bacteria, fungi, and arthropods. A good example of organisms living in the soil is an earthworm.

Katen [24]

Answer:

They had a large brain size of 700 to 1,250 cubic centimeters and large brow ridges with a nuchal torus at the back of the skull.

Explanation:

<em>Homo erectus</em> was one of the species of the homo genus which were considered the first species to have the human-like the feature that is they can stand upright on two legs and were therefore referred to as the upright man.

They showed many evolutionary advances over their ancestors called Homo Australopithecus as they showed encephalization. Encephalization refers to the increase in the size of the brain due to more neuronal complexity and neurogenesis and they possessed about 750 to 1250 cc brain size.

They showed torus at the back of the muscle which can hold the muscle of the neck and also showed the large brow ridges in the front of the skull.

Thus, the selected option is the correct answer.
