As our evolution continues, the crucial role of diet hasn’t gone away. Genetic studies show that humans are still evolving, with evidence of natural selection pressures on genes impacting everything from Alzheimer’s disease to skin color to menstruation age. And what we eat today will influence the direction we will take tomorrow.

That’s according to a new research paperthat argues for a new way of thinking about our phone addiction. The authors claim that hundreds of thousands of years of evolution made us social in order to survive–and social media simply is driving this deeply ingrained human behavior into overdrive. This isn’t actually all that bad, they say, if you follow two basic rules.

It is a bit of a stretch, but by no means impossible or even unlikely that a hybrid or a chimera combining a human being and a chimpanzee could be produced in a laboratory. After all, human and chimp (or bonobo) share, by most estimates, roughly 99 percent of their nuclear DNA. Granted this 1 percent difference presumably involves some key alleles, the newgene-editing tool CRISPR offers the prospect (for some, the nightmare) of adding and deleting targeted genes as desired.
