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.
Researchers have discovered that learned behaviors can be inherited for multiple generations in C. elegans, transmitted from parent to progeny via eggs and sperm cells.

The next President and Congress must adopt policies to phase out domestic fossil fuel production as part of any comprehensive climate policy effort like a Green New Deal. This fossil fuel phase out should occur in tandem with policies to boost renewable energy and ensure a just transition for workers, communities and tribal nations.
The discussion of micro- and macroevolution and of the fossil record almost sounds like something from the Discovery Institute blog, the kind of honest assessment of Darwinism which today could cause a biology teacher to lose his/her job. The Times writer assures us, however, that all of this does not suggest “weakness in the fact of evolution”, only in the “perceived mechanism.”
Researchers have identified special regions of the genome where a blood sample can be used to infer epigenetic regulation throughout the body, allowing scientists to test for epigenetic causes of disease.
