Answer:

Option A

Explanation:

Earlier it was believed that the human teeth especially the canines were a distinguishing factor for determining whether as species belongs to the family of humans or not. But only apes used to have such teeth but not the hominids and hence later on bipedalism (upright walking on rear limb) was considered as distinguishing factor.  

However, it was later recovered that certain other characteristics such as larger brains,  behavioral characteristics  etc, also distinguished hominins from other primates

Hence, there exists no agreed upon phylogeny for early hominins but general patterns of early hominin evolution can be understood.

Option A is correct

HELP PLS, AND EXPLAIN, I BEG: Nancy needs to do a scientific investigation for her class. She is interested in pottery, plants,
ozzi

Answer:

A. What length of time is best to use for the firing of pottery to make it strong?

Explanation:

Point A

What length of time is best to use for the firing of pottery to make it strong?

This is a scientific question for Nancy since while making pots from black mud, it is very important to know how much time is required to fire the pot in order to make it strong. Because if we fire it for too long the pot may be become too hot and will eventually crack. While if we fire for less time it will not become hard enough to withstand its shape. So knowing the proper time to fire the pot is very essential in pottery.

Point B, Point C and Point D are not scientific investigations since it includes ones likes and dislikes, quantities and numbers of goal scored which is not scientific.

Hence, option A is the correct answer.
