Is self‐fertilization an evolutionary dead end?

@McGillHaricots My guess is Godzilla is well aware of the challenges s/he faces (https://t.co/fGJYgH51m1), which to be honest is probably why s/he is so angry all the time.

“With over five decades in their wake, modern studies of plant mating system evolution have yielded data on selfing and outcrossing rates for approximately 500 species and numerous analyses of the history of mating systems.” https://t.co/bcE9lifYfU

“Selfing may limit purifying or positive selection, but these lineages may not persist long enough to leave footprints of attenuated adaptation in the genome. Phylogenetic studies have shown that the origins of selfing are often rather recent.” https://t.…

“There is considerable support for the notion that selfing lineages harbor less nucleotide polymorphism, although it is unclear how genome-wide nucleotide polymorphism is linked to potential adaptive phenotypic evolution.” https://t.co/bcE9lifYfU
