"Up to half of the nucleotide substitutions found in independent lineages under uniform selection are the same." https://t.co/lSZ91vmh03
"The most convincing evidence of parallel genotypic adaptation comes from artificial selection experiments." https://t.co/lSZ91vmh03
"There is increasing evidence...that parallel adaptation at the genotypic level may be more frequent" than before. https://t.co/lSZ91vmh03
"There is increasing evidence, however, that phenotypic variation sometimes has a simple genetic basis." https://t.co/lSZ91vmh03
"Phenotypic differences were thought to be controlled by many genes." https://t.co/lSZ91vmh03
"Until recently, parallel genotypic adaptation was considered unlikely." https://t.co/lSZ91vmh03
