The T. rex had a body temperature similar to our own

The fearsome Tyrannosaurus rex might have had an internal body temperature similar to that of modern-day elephants — and not too dissimilar to humans. By examining the arrangement of isotopes in the enamel of fossilised T. rex teeth, researchers estimate that the dinosaur’s internal temperature was approximately 36 °C. Narrowing down the creature’s body temperature can hint at what kind of diet it needed to sustain its homeostasis, and where it was able to roam.

Non-Human Primate Communication May Follow Grammar Patterns Once Thought Uniquely Human

The vocalisations of the common marmoset (Callithrix jacchus), the olive colobus monkey (Procolobus verus) and the bonobo (Pan paniscus) all appear to contain patterns that resemble complex elements of human grammar. Researchers used mathematical models to analyse clips of these primate communications and identified some elements similar to supra-regular recursion — a grammatical structure that requires a listener to process a word or statement nested within a wider sentence without context. This level of complexity was thought to be unique to humans.
