Unraveling the Mechanisms of Human Brain Evolution: A Challenge to Neo-Darwinism?
The human brain, an organ of unparalleled complexity, has long been a source of fascination and inquiry. Its evolution, a journey spanning millions of years, has endowed us with unique cognitive abilities, setting us apart from all other species. The journal article "Unraveling mechanisms of human brain evolution" delves into the intricate genetic, epigenetic, and transcriptomic factors that have shaped this remarkable organ. While the article primarily focuses on elucidating the mechanisms driving human brain evolution, it indirectly raises questions about the traditional neo-Darwinian framework, suggesting a need for a more nuanced understanding of evolutionary processes. Neo-Darwinism: A Brief Overview Neo-Darwinism, the modern synthesis of Darwinian evolution with Mendelian genetics, posits that evolution proceeds primarily through the gradual accumulation of small, random genetic mutations. These mutations are then subject to natural selection, with benefici
