The animal kingdom is extremely diverse and animals have had unique and interesting ways to adapt to modern conditions. Here we explore the topic of animal evolution, and look at examples of how animals have adapted to different stimuli in their environments over time.
In some examples of convergent evolution, species evolve the same solution to a problem but take a different genetic route to get there. In other cases, the convergence takes place at the molecular level and the same genetic changes occur in different species.
