LivingMetal said: I've seen some of these examples. But birds are still birds, moths are still moths, toads are still toads, etc. It's the ability to adapt to survive within their DNA structure. |
There are plenty flighless birds, frogs start out as fish, caterpillars become butterflies. All species share a lot of the same DNA. DNA for a wing is very similar to DNA for a fins or a limb. There are plenty species that don't neatly fit into kindergarten classification. Species definition is a problem onto itself as there are no neat boundaries. For example Mesodinium chamaeleon crosses the boundary between plants and animals.
