Do we evolve over time, or instantly?
The eyes - one of the most complex peices of our bodies, how did we come to have them? Did we have 1/4 of an eye, then half, then a whole eye, or simply had two full eyes one day.
Birds, mammals, reptiles, all have eyes. Did we all come from the same species, and evolve into different groups? Since we all have relatively similar lungs, eyes, a brain, nervous system and skeletal structure?
Is evolution pre-written into genes? How did it get there?
Answers and views from all sides are fully welcomed.
