All an evolutionary storyteller has to do is to start with the apparently simplest version, ignore the neural equipment that has to be present for an organism to make any use of a «photon receptor,» and spin a charming tale about how a tiny primitive light - sensing cell might grow up to be a full - fledged eye.

Recombinant DNA research has been done primarily on bacteria, one - celled organisms smaller than animal or plant cells and simpler in structure, yet capable of very complex chemical activity.

I don't mean taking for granted things that are totally unproven, like the fundamental process of complex organisms spontaneously emerging from simpler ones.

I'll even offer observations - humans have manipulated existing organisms dna, created new virus and bacteria, clone animals, and attempt to create new animals - yet simple minded folks still reject the idea that another more intelligent creature might have done the same thing and created life on earth in the same fashion while at the same time acknowledging that there is a strong likelihood of other life existing in this universe - talk about being dumbed down and arrogant.

Technologies to visualize neurons in live subjects — as well as process such gargantuan volumes of data — do not yet exist, so only post-mortem studies in simpler organisms are even presently imaginable.

The reason for this is very simple: when you don't eat enough to support the healthy functioning of every system in the organism for longer periods, your body slows down some of them in an effort to spare energy for more vital functions, and the reproductive system is the first one to get shut.
