FRAGMENT FROM NATURE contemplates the curious phenomenon of double fertilization in flowering plants, a large group of living creatures. This is a process unlike the reproduction of animals or other plants, and appears to confer no particular competitive advantage. Perhaps it is a pure happenstance of evolution, wrought by pure accident, which survived. But, just like the mating fruit-fly where the female genes become massively lit up in short order, so also, the cross-talk and molecular chatter that accompanies the pollen tube entry is very impressive. Hardly dumb sessile creatures.
