Final answer:
Mobbing behaviour as an example of divergent evolution is false. Divergent evolution involves species becoming more dissimilar due to different environmental pressures, while convergent evolution refers to unrelated species developing similar traits in response to similar challenges.
Step-by-step explanation:
The statement that mobbing behaviour is an example of divergent evolution is False. Mobbing behaviour, where small birds collectively respond to predators, does not by itself suggest divergent evolution. Divergent evolution refers to two or more species developing different traits or adaptations due to different environmental pressures, leading them to become increasingly dissimilar. On the other hand, mobbing behaviour can be an aspect of coevolution, where two or more species influence each other's evolutionary pathway, often due to direct interactions like predation.
An example of divergent evolution would be the development of different beak shapes in birds that have adapted to various ecological niches over time. However, convergent evolution refers to the process where unrelated species develop similar traits independently, often as a response to similar environmental challenges. An example of convergent evolution is the development of wings in both bats and birds to adapt to flight, despite their vastly different ancestries.
