"Sea Lamprey: Surprising Similarities in Brain Development with Humans"
A study from the Stowers Institute for Medical Research reveals that the hindbrain of sea lampreys and humans is constructed using a remarkably similar molecular and genetic toolkit, shedding light on the evolution of vertebrate traits. The research, published in Nature Communications, identifies a common molecular cue, retinoic acid, involved in guiding hindbrain patterning in sea lampreys, suggesting that this process is ancestral to all vertebrates. The findings challenge previous assumptions about the differences between jawless and jawed vertebrates, highlighting the close evolutionary relationship between sea lampreys and humans.
