As time passes, just the "fittest" features of your species survived. Inevitably, just after ample time passed, these little adaptations would add up to create new species. These changes are exactly what helps make us human.
I designed a set of gifs of user designed creatures around on my Web site. Do you do have a neat creature style you want for being highlighted? See in this article for more info.
This phenomenon is usually a essential to knowing not merely predator-prey interactions, but in addition many other ecological phenomena for instance: host-parasite interactions (like condition evolution), and also the interaction concerning a lot of flowering plants and their pollinators (an extreme illustration getting orchid flowers that mimic female insects to get their pollen transferred by male insects).
