In what way did an increased skull and brain size affect hominid evolution from early ancestors to modern humans? they became less reliant on vision and more reliant on all of their senses. the larger brain caused their overall body size to decrease. they became less reliant on tools and social interactions. the gestation and infant care period increased to allow the brain to develop.

The correct answer is - The gestation and infant care period increased to allow the brain to develop.

With the constant increase of the size of the skull and of the brain, as well as its ever growing complexity of the neuron network in the hominid brains, the result has been longer gestation and infant care period.

This has been the result because such a large and complex brain needs much longer time to fully develop. That has made the newborn and afterwards the youngsters, to be totally dependent on the adults, to a point where the hominid youngsters were still not well developed while other species have born, grown, and died.

it would lead to upper respiratory infections and pneumonia.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
