survival of the fittest

Bill Hamilton transformed biology
applying maths where few had tried before
the science he leaves to his progeny
now calculates what had been metaphor
to Darwin's doubters, altruism's odd
but Bill made clear, it's all about the genes
no reason one should be invoking God
to understand what good behaviour means
hypotheses get weighed and falsified
advancing the frontier of what we know
and ignorance is left no place to hide
unless you let some old book tell you so
economists don't toss ideas that crash
but in LifeScience, we throw out the trash
