Corals use epigenetic tricks to adapt to warmer and “more acidic” water

After half a billion million years of climate change, I’m shocked, shocked I tell you, that life on Earth (and specifically corals) have so many ways to cope with the climate changing. After all, it’s natural (if you are trained by Greenpeace) to assume that corals can only survive in a world with one constant stable temperature just like they never had.

We already knew corals chuck out the symbionts that don’t work so well and pick up better partners. Plus, evolution  left a stack of genes lying around that were honed  in a world that was warmer, and natural selection has a way of amplifying better combinations as conditions shift. Then there is the way corals can be reseeded from safe sites, far away. Now we find out that corals can use epigenetics too.

Epigenetics is that kind of spooky effect where people can inherit the exact same DNA code yet it works or doesn’t work depending on whether it was Dad’s copy, or Mum’s, or whether parents were starved, fearful or stressed. It’s weird, see more [...]
