Can species adapt to a hotter world?
New research shows that species evolve faster to adapt to the climate getting colder than to it getting hotter, and that the rise in heat they can adapt to has limits.
Red honey ants endure temperatures above 50 °C in the Australian desert, while the springtail survives extreme cold of -30 °C in the Antarctic.
A new study, published today in Nature Communications, explores how evolution has prepared some species to withstand these temperatures and how fast different species evolve to changing temperatures.
Physiological tolerance to heat and cold determines where on the planet an organism can survive yet we have limited understanding of how this tolerance evolves over time. This is an area of increasing interest as the climate heats up more quickly than ever before.
