the foxp2 sequences of mice were most different from those of
FOXP2 The FOXP2 gene is highly conserved in mammals.[41] Human gene differs from non-human primates by the substitution of two amino acids, threonine to asparagine substitution at position 303 (T303N) and asparagine to serine substitution at position 325 (N325S).[32] In mice it differs from that of humans by three substitutions, and in zebra finch by seven amino acids.[17][42][43] One of the two amino acid difference between human and chimps also arose independently in carnivores and bats.[13][44] Similar FOXP2 proteins can be found in songbirds, fish, and reptiles such as alligators.[45][46]
Fox (surname) Fox or Foxe or Foxx is a surname originating in England and Ireland. The derivation is from the Middle English "fox", itself coming from the Old English pre 7th century "fox". The surname first appears on record in the latter part of the 13th century, with the first recorded spelling in 1273 to be that of John Fox in the "Hundred Rolls of Yorkshire", England.[2] In Ireland, Fox is mainly an Anglicised form of the Old Gaelic "Mac a'tSionnaigh" (son of the Fox).[2]
