Hypothesis 4 (Biological Determinism) - Baba Brinkman

Evolution is the only theory that science hasn’t rejected

For the origins of life, and humans are no exception

And if behaviour has a genetic basis and it’s naturally-selected

Then human nature hasn’t changed since the days of Homo erectus

The modern-day skull houses a stone-aged mind

‘Cause achieving major change in a chromosome takes time

You know how kids like sugar on their cornflakes right?

Well, that’s evolution in action — we can follow a straight line

Back to our ancestors' food preferences and incest-avoidance

And mate preferences, and aversion to ingesting poisons

Evolution even explains why the female chest is so boisterous

So if you think human nature is flexible, get set for disappointment

‘Cause selfish genes lead to selfish behavior

And alpha males impregnate the wives of their helpless neighbors

Human beings are socialized to deny their hellish natures

But we might as well embrace it now, and deal with the outcome later
