: Hey guys - posting comments was broken for some people, but it should be fixed now. Let me know
if there's any more issues.
I do realize this is not how biological evolution works. Organisms do not consciously change their genes. But genes do randomly mutate by various mechanisms and once in a great while there's a mutation that makes the organism slightly more likely to pass his genes on to future generations.
I'm not sure if spiciness is a defense to prevent animals from consuming, a delicious adaptation that encourages us to grow them ourselves, or a man made selection feature like those tiny yapper dogs.
