Pugs, Persian cats, and other smushed-face cats and dogs are more similar to one another than they are to the wild animals ...

This helps the species to be more successful in its habitat. It’s natural selection at work. In some examples of convergent evolution, species evolve the same solution to a problem but take a ...

Perhaps the most famous example of convergent evolution in aquatic animals is the striking similarity between dolphins and sharks. Dolphins are mammals, while sharks are fish, yet their body ...

This is a dramatic example of convergent evolution, when organisms that aren't closely related evolve similar traits as they both adapt to similar environments. There are a finite number of ...

The analogy is telling because it introduces often overlooked critical aspects of convergent extension: for example, what are the cells sensing for? People forming a queue may 'cut in' between two ...
