If this is generally the case, new feeding techniques would
spread rapidly through populations, as individuals that generate
innovations at a high rate would also have access to
the innovations of others through fast social learning. If acquiring
the new techniques had a strong effect on survival,
there would be a much stronger fitness differential within the population than under zero or negative correlations between
innovation and social learning. This is because individuals
that do poorly on innovation tend to also do poorly on social
learning and thus have little or no access to the new technique
through either process. This is in sharp contrast to the
individuals that both learn quickly from others and innovate
often. An obvious next step would be to simulate the effects
of these fitness differentials and cultural transmission rates
on behavioural drive.
