In many ferns, two or more (close) species can cross, giving viable progeny, which can have a range of outcomes. Often, whole new species are founded and enter the competition. There are Strategies (hybrids don’t develop female reproductive organs, meaning they aren’t ‘polluted’ by parents’ genomes; yetthey produce sperm and so can fertilize parents etc.) and Counter-Strategies (inhibiting others’ growth, having faster sperm etc). It’s a whole world and it gives one this utterly breathtaking feeling that evolution is:)
...and kin selection. Don’t forget kin selection!
