@Fatal Freedoms,
You also have to ask what other paths could evolution take us on, it's only up to the imagination what species there could have been, but everythings been covered by the looks of it, we have aquatic life, mammals, reptiles, flying creatures, microscopic, insects, spiders etc. etc. theres nothing really out of its league. A monkey with wings, but it's still a monkey, a horse that can swim buts its still a horse, a weird creature that has a bill like a duck, it lays eggs, is a mammal, has otter feat and beavor tail the male speciemen has a venenmous spur ahh that's a platypus....
