California saw its worst drought in 10,000 years between 2012 and 2015, remembers the Washington Post. And yet genetic analyses of California's scarlet monkeyflower "found that many rapidly evolved... allowing them to cope with water scarcity and rebound from decline."


"The fact that certain organisms are able to adapt just because of genetics that are already present is a great source of hope," said Daniel Anstett, a plant biologist at Cornell University and lead author on a new study on the issue. "It's one more arrow in the quiver of different ways that populations might be able to survive the massive climate change we're inflicting on the planet." The recovery of [Sequoia National Park's] scarlet monkeyflowers offers rare, real-world evidence of what scientists call "evolutionary rescue," according to the study published Thursday in the journal Science. It suggests that some species may be able to evolve quickly enough to keep up with the accelerating consequences of human-caused warming — essentially saving themselves from extinction.

This discovery could help people decide how to distribute limited conservation funds by pinpointing which species have enough genetic diversity to be resilient, ecologists Mark Urban and Laurinne Balstad, who were not involved in the study, wrote in a separate analysis published by Science. "The challenge going forward is to identify when evolutionary rescue is possible, when it is not, and how to rescue those species that cannot rescue themselves," Urban and Balstad wrote.
