coincidence or divine intervention?

I have an evolution question.

How did the eyeball evolve?

And I don't mean crummy little light receptors. I am talking about sharp-focus bi-focal colour vision.

Becuase if you remove or change any component of the eye by less than half a percent the whole eye ceases to work.

So I was wondering if anyone could tell me how it evolved.

cj, you think too much. take two hits and pass it to your right. dont be greedy with that xxxxx.

and doug, to say you dont believe in evolution would have been like believing the world is flat. there is evidence with studies of finches in the galapagos, fruit flies, etc. its data. not just prophetical bible stuff.

i cant give you an answer to your ? because i'm not a scientific genius or a genius of any kind nor am i even knowledgeable in that area.

i believe in evolution, but i dont believe in darwinian natural selection as being the only driving force behind it, theres got to be more to it for it to add up.
But then im an agnostic, so its in my nature to question every theory.

[dougirwin13]

Are adaptation and evolution the same thing? Maybe.

Did I say I don't believe in either? Nope.

Did I ask a question? Yep.

BUT - if something is disproved in once instance the supporting theory is flawed and invalid. The scientific method specifically indicates that any such theory needs to be reworked until it can account for the anomaly.

Still no answers to my question?

Anyone like Chai Tea, I think that is one of the greatest miracles in the world. Tea that smells like Pumpkin Pie.

The Eyeball thing. I think that since we are basically a socialized colony of cells (a bunch of individual cells that rely on each other, and form a greater multi cellular oganism) the presence of light was a stimuli, causing the need for certain cells to re-colonize in the form of an eyeball in order to have a developed receptical sensor for the neuopathways to interpet and carry information to the brain for processing and decernitation. WHATEVER IN THE HELL THAT MEANS. PASS THE DOOBIE.

Chai Tea. That is indeed the stuff-- with a cinnamon stick in it too. Yum.

Here is an abstract of a journal article I located. Hopefully I can locate the full text of the article:


In order to clarify the morphological uniqueness of the human eye and to obtain cues to understanding its adaptive significance, we compared the external morphology of the primate eye by measuring nearly half of all extant primate species. The results clearly showed exceptional features of the human eye: (1) the exposed white sclera is Void of any pigmentation, (2) humans possess the largest ratio of exposed sclera in the eve outline, and (3) the eye outline is extraordinarily elongated in the horizontal direction. The close correlation of the parameters reflecting (2) and (3) with habitat type or body size of the species examined suggested that these mo features are adaptations for extending the visual field by eyeball movement, especially in the horizontal direction. Comparison of eye coloration and facial coloration around the eye suggested that. the dark coloration of exposed sclera of nonhuman primates is an adaptation to camouflage the gaze direction against other individuals and/or predators, and that the white sclera of the human eye is an adaptation to enhance the gaze signal. The uniqueness of human eye morphology among primates illustrates the remarkable difference between human and other primates in the ability to communicate using gaze signals.

lmfao..I kept reading it Thai Chee..Like that weird yoga thing. I was wondering whether you had all gone crazy?!

My bad

[hawaiiSUCKSexceptsurf]

when a species morphes in a way and its children have that same abnormality, and the characteristic is passed on and on, it is evolution.

adaptation occurs within a single generation.

im agnostic, but i dont like orginized religion.

How did the eyeball evolve?

.. why would you need to know !



Would it be fair to say that most animal forms evolved from ocean dwelling creatures then if so .. " the eyeball needed to cope with light refraction and colour spectrums under the ocean would by nature be forced to evolve once it had made it to dry land .. different spectrum waves , ultra violet etc etc .. it would as the animals did progressively evolve into what was required for 'sight' on dry land ..in essence a simple ongoing upgrade which we without knowing are all undergoing now to deal with different light parameters and spectrum waves as time rolls on ..

A short non-sensical sensible theory on the evolution of my eye

and i thought you were just the forum stonner

lmfao .. you knowz it





still lmfao 5mins later .. great comedy timing bro
