  2. Há 2 dias · Marsupials have split from placental mammals about 120-180 million years ago. If marsupials had functional brown fat and its thermogenic protein, it would suggest that the organ existed before this split. Since it does not, it likely evolved later,” says Susanne Keipert. Using bioinformatic tools on UCP1 sequence information from many animals ...

  6. Há 1 dia · There are several competing scenarios for the long-term evolution of the universe. Which of them will happen, if any, depends on the precise values of physical constants such as the cosmological constant, the possibility of proton decay , the energy of the vacuum (meaning, the energy of "empty" space itself), and the natural laws beyond the Standard Model .
