Climate adaptation may be a family affair

Newborn reef fish can cope with changed water conditions if their parents have already adjusted

A newfound ability of reef fish to adapt to shifting conditions over the course of two generations indicates they might be less vulnerable to climate change than previous research has suggested.

But they showed no adverse impacts if their parents had lived under the same conditions prior to breeding.
