Scientists have observed numerous trends in structures and characteristics during the evolution of hominids. One trend is
the change in brain size. Which of the following best describes the pattern of brain sizes over time?
As hominid species changed during the last 6 million years, brain size typically increased.
The hominids with the largest brain sizes evolved before hominids with smaller brain sizes did.
The latest species of hominid rapidly developed a large brain size during the last 200,000 years.
Early hominids developed large brain sizes, and later hominids maintained those large brain sizes.

As hominid species changed during the last 6 million years, brain size typically increased.
There was a __rather rapid__ development in brain size approximately between 800,000 and 100,000 years ago, leading to larger brains.
The increase in brain size was crucial for survival as it allowed for the development of culture and technology, helped in exploiting the environment, and enabled humans to become dominant land animals.
