Dear MEL
Topic Readers,
A change in
diet may have helped our brains get so big
Why are human
brains larger than the one of other animals’ or relatives’, whether living or extinct
ones?
It has been
believed that social behavior contributes how the brain of certain species
evolves over time. Think of a solitary primate that never interacts or
communicates with others. The part of the brain that controls communication
will never be activated, and any useless part of the body never evolves but degenerates
over time. If that is the case, the larger the social group is, the better for
brain development is?
New study
finds that nutrition is another factor that affects the brain size of primates directly
and indirectly. Some researchers found that the better the nutrition is, like
fruits over leaves, the larger the brain size of certain primate spices is.
This sounds understandable, but are fruits easy to get throughout the year and
within the territory of the social group?
Enjoy reading
and learning the links between social activities, diet and brain size.
