From their first revelations in the last century until now Darwin’s theories continue to evoke strong
feelings and debate. In this essay the recent developments in evolutionary biology and biophysics are
discussed against the background of the apparent constants of intelligence and genetics. The notion of
‘selfish genes’ and its economic context is probed in the light of theories about inclusive fitness, grouprelated
adaptation and self-regulation. The disappointing results of the Human Genome Project in terms
of numbers of genes has led researchers to continue to seek answers outside the sphere of genes to a
better understanding of human nature and nurture. These new findings are important for psychologists.
In particular, the essay points out how recent explorations in these related sciences can lead to
psychological strategies that can help practitioners support their clients in the field of health and
education.
