The classic objection to hopeful monsters - that a pig with wings has no chance of finding a similarly endowed mate - misses the point that if you have one pig with wings, there are more where that came from - in the developmental pathways of the relatives of Archaeoptopig.

Isn't this "classic objection" an objection only if you assume that the mutation is recessive? If wings make a single Archaeoptopig a particularly attractive mate, there could still be lots of Arhaeoptopigs in the next generation.
ReplyDeleteI think the point is more like if you see one, it means there are others around. If the genes are available in the one it has to be available in a large group of them. There is no way only one could be produced. Also the odds of seeing one and there only being the one are so astronomical that there is a good chance there are others.
