Un fossile vieux de 250 millions d'années révèle les origines de l'audition des mammifères
os mâchoire fossile mammifères crâne
L’audition sensible pourrait avoir évolué chez les ancêtres des mammifères bien plus tôt que ne le croyaient les scientifiques. En modélisant la façon dont le son se déplaçait dans le crâne de Thrinaxodon, un prédécesseur mammifère vieux de 250 millions d'années, les chercheurs ont découvert qu'il utilisait probablement un tympan précoce pour entendre les sons aériens. Cela remet en question l’idée répandue selon laquelle ces animaux « écoutaient » principalement à travers leurs mâchoires ou leurs os. Les résultats révèlent qu’une caractéristique clé de l’audition des mammifères modernes prenait déjà forme au plus profond de la préhistoire.

Un minuscule fossile du Devon vieux de 242 millions d’années bouleverse les hypothèses des scientifiques sur les premiers membres de la lignée des lézards. Au lieu des charnières du crâne et des dents du palais typiques des lézards et des serpents modernes, cette ancienne créature présente un mélange surprenant de traits primitifs et inhabituels, ainsi que des dents étonnamment grandes en forme de lame. Les scans synchrotron haute résolution ont révélé des détails invisibles à l'œil nu, aidant ainsi les chercheurs à nommer la nouvelle espèce Agriodontosaurus helsbypetrae

Les humains ont évolué plus vite que n’importe quel autre singe
croissance évolution crâne
Les scientifiques de l'UCL ont découvert que les crânes humains évoluaient beaucoup plus rapidement que ceux des autres singes, reflétant les forces puissantes qui conduisent la croissance de notre cerveau et l'aplatissement de notre visage. En comparant des modèles 3D de crânes de singes, ils ont montré que les humains changeaient environ deux fois plus que prévu. Les résultats suggèrent que des facteurs cognitifs et sociaux, et pas seulement l’intelligence, ont influencé notre évolution.
