A host of recent examples in plants and animals manifests how human-driven climate change can bring nature to its knees and force the pace of evolution. Ants getting more tolerant to urban “heat islands,” squirrels reproducing at much younger age, flowers blooming well in advance in the year and many more tales of transformation.

The rigors of climate change could soon dictate the trajectory of evolution in Homo sapiens as well, causing shifts not only in the internal working of our bodies but also transforming our appearances, notes NBC News.

As rising temperatures impact agriculture eventually leading to shifts in food availability, our digestive systems may evolve, and changing diets may also transform our microbiomes. Mass migrations, triggered by rising sea levels, may erode racial differences between populations over time.
