F. The discovery of corvid intelligence challenges our understanding of evolution. It suggests that complex intelligence has evolved along very different paths. Birds and mammals last shared a common ancestor over 280 million years ago. Yet, both groups have developed similar cognitive abilities. This is a prime example of convergent evolution, where similar traits evolve independently in unrelated groups due to similar environmental pressures.
One of the most well-known examples of corvid intelligence is the use of sticks by crows to retrieve food from hard-to-reach places. For example, a crow may use a stick to dig up grubs from the ground or to retrieve food from a narrow crevice. This behavior requires a high level of problem-solving ability and innovation.
