Researcher: The discovery of uncommon wiwaxiids fossils in this time frame suggests the animals lived on Earth for a far greater span of time than previously understood.
Because, on a large scale our universe is predictable
Animals first developed fever as a response to infections: the higher body temperatures primed their immune systems. At the time, 600 million years ago, virtually all animal species were cold-blooded. They had to spend long periods of time in warm areas of their habitat to achieve fever-range body temperatures. A researcher believes that pathogens may be the reason why warm-blooded creatures first emerged.
We know bees get the concept of zero and can do basic math. Now researchers have discovered they may also be capable of connecting symbols to numbers. It’s a finding that sheds new light on how numerical abilities may have evolved over millennia and even opens new possibilities for communication between humans and other species.
