Unveiling Evolutionary Links: Sea Lampreys Shed Light on Human Brain Development
Source-scitechdaily Ancient Connections Unveiled Recent research conducted at the Stowers Institute for Medical Research has uncovered surprising similarities between the brains of humans and sea lampreys , ancient marine creatures dating back 500 million years. Led by Investigator Robb Krumlauf, Ph.D., the study, published in Nature Communications on February 20, 2024, delved into the molecular and genetic makeup of the hindbrain, a vital component controlling essential functions like blood pressure and heart rate, in both sea lampreys and humans. Insights into Evolutionary Pathways The study’s findings shed light on the evolutionary processes that have shaped vertebrate brain development over millennia. Despite the stark physical differences between sea lampreys and humans, such as the absence of a jaw in the former, researchers discovered a striking similarity in the molecular cues guiding hindbrain patterning. This revelation challenges previous assumptions and suggests ...
