A study led by Daniel Sol, CISC researcher based at CREAF, shows that cities preserve 450 million years less evolutionary history compared to natural environments. Birds capable of surviving in highly urbanized environments have undergone recent evolution. The arrival of exotic species does not compensate for poor urban evolutionary diversity.

Birds that live in changing environments have larger brains
