Robin Dunbar proposed, based on primate research, a relation between brain size and the number of social relationships an individual can maintain. Dunbar proposed, furthermore, that the evolution of language greatly reduced the mental effort required to maintain the same number of social relationships.
How this all relates to the evolution of the brain is not immediately evident to me, although it undoubtedly does.

How did human evolution start?
Human evolution began millions of years ago with our common ancestors, who lived in Africa. Over time, different species of hominins emerged and evolved, eventually leading to the development of modern humans, Homo sapiens. Key events in human evolution include bipedalism, tool use, increased brain size, and social behavior.
How does the position of the foramen magnum in the skull relate to the evolution of bipedalism in humans?
The position of the foramen magnum in the skull, which is where the spinal cord connects to the brain, shifted forward in human evolution. This forward shift allowed for a more balanced upright posture, which is a key adaptation for bipedalism, or walking on two legs. This change in the foramen magnum position is considered a significant factor in the evolution of bipedalism in humans.
The development of humans was directly dependent on?
The development of humans was directly dependent on factors such as evolution, adaptation to changing environments, use of tools, development of social structures, and increased brain size and cognitive abilities. These factors contributed to our survival and success as a species.
What is a Stegasaurus' brain the same size as?

What theory of how human evolved?
The theory of human evolution proposes that modern humans evolved from earlier hominid species through a process of natural selection and genetic adaptation over millions of years. Key stages in human evolution include the development of bipedalism, the enlargement of the brain, and the emergence of more complex tool use and social behaviors. Multiple hominid species coexisted at different points in history before Homo sapiens became the dominant species.

Dunbars number stated that?
The human brain can’t maintain relationships with more than 150 people - apex
What is Dunbars number states that?
Dunbar's number is a theoretical cognitive limit to the number of stable social relationships that an individual can maintain, typically estimated to be around 150. This concept, proposed by British anthropologist Robin Dunbar, suggests that the size of a person's social network is constrained by the brain's capacity for social cognition. The number encompasses relationships in which individuals are able to know each other well enough to support one another in times of need. Beyond this limit, relationships tend to become more superficial.
What animal has the simplest brain mechanisms?
Evolution of brain is called cephalization. Worms are found to have the simplest brain mechanism and have simple straight forward nervous system i-e head to tail.
What is the cerebral cortex or new brain?
The cortex means "cork". It is called this because it is like the outer layer of a tree. This "new" brain was laid down last in the evolution of the brain in our species.
