Comment la vie a commencé - Alexandre Meinesz D’où vient la vie ? Comment est-elle apparue sur Terre ? Quels ont été les premiers organismes vivants ? À quoi ressemblaient les ancêtres de formes de vies actuelles ? Alexandre Meinesz spécialiste des milieux marins et des premiers organismes ayant colonisé la Terre (les algues), abordera les mystères de la vie avec un éclairage original sur l’évolution du vivant, différent de celui des microbiologistes, des généticiens ou des paléontologues.

Are We Still Evolving? Exit from comment view mode. Click to hide this space NEW HAVEN – Many public-policy decisions are based on implicit assumptions about “human nature,” and it is currently popular to speculate about how evolution might have shaped human behavior and psychology. But this raises some important questions: are humans continuing to evolve – and, if so, is our basic biological nature changing – or has modern culture stopped evolution? For some traits, we do not have to speculate – we can measure and compare on the basis of studies covering thousands of individuals over several generations. Such studies have not yet been done on most of the traits where speculation is popular, but they have been done on some traits of medical interest.
What have we learned? Scientists are taking two approaches. Some scientists, myself included, have taken a different approach. The message of this approach is also clear: natural selection continues to operate in modern cultures.
