how we as a species are evolving.
Simply put, in order to have an idea of what humans might look like, scientists need to
a)
b)
c)
changes in where we might live, what we might eat, or what medicines we might use.
GENETIC CHANGE
Even though our societies and lifestyles might change, we are still largely
