Groundbreaking New Theory of Evolution: Adaptive Tracking Explained

New theory of evolution
Discover the latest breakthrough in evolutionary biology from University of Michigan researchers. This study challenges the long-standing neutral theory of molecular evolution, revealing that beneficial mutations are far more common than thought, but environmental changes prevent them from dominating populations.
In this video, we dive into the key findings published in Nature Ecology and Evolution. Learn how deep mutational scanning in yeast and bacteria showed over 1% of amino acid changes improve fitness. Yet, in stable environments, adaptation surges, while shifting conditions lead to 'adaptive tracking with antagonistic pleiotropy' – where mutations help in one setting but harm in another.
Explore why long-term genetic changes appear neutral despite ongoing selection. Simulations confirm this model matches the molecular clock puzzle. Implications for human genetics, climate change adaptation, and disease evolution are huge.
