video description

Rating: 4.0; Vote: 1
The human eye is an amazing mechanism, able to detect anywhere from a few photons to a few quadrillion, or switch focus from the screen in front of you to the distant horizon in a third of a second. How did these complex structures evolve? Joshua Harvey details the 500 million year story of the human eye. Lesson by Joshua Harvey

And thru the power of bias unscientific, unfounded speculation and the omission of much of the empirical science we once again have an example of the incredible power of random genetic mutations to change a
light sensitive cell into into an optical wonder which has the ability wit the visual cortex to change chemical
electrical charges into over 10, 000, 000 million colors, about 600 pixel clarity, capable of recognizing as little
as one photon of light. textures, shapes, movement and speeds and able to visibly establish every thing
on earth. But unfortunately like so many evolutionary explanations, it only requires the same magic that can
turn a wolf into whale or mud into life or simply science fiction.

Speculation and assumption gone absolutely wild. Natural selection is comatose. It directs nothing. Random copying errors lack the power to create the required never before seen proteins. or overcome irreducible complexity such as a part of the brain that interprets signals, an optic nerve, and light sensitive cells. Individually they offer no benefit to the creature whatsoever. This video makes quantum leaps over the massive complexity involved. and hopes you will be gullible enough to swallow it. The mutation lottery had been imbued with deific powers by proponents of the theory. that would never occur in the real world. It's a lottery not a computer program. Macroevolution is a worldview. not science.

Atheist is as cringy as religious people when they claim that there's no god which contributes to the evolution of humankind or the existence of the universe. Like, have you ever read baruch spinoza's idea of god? Or daoist idea of supreme being? There are multitude of interpretations of god or gods in the world, even between those who hold same belief system. Broaden your knowledge, stop acting like religion is not a complex system which shapes the world as we know it.

I'm not sure why evolution is supposed to be some kind of mega theory to disprove God: / I actually went from agnostic to full believer after learning deeper about evolution and harmonizing it with my knowledge of Physics: / Like truly speaking if you know how to establish a connection between physics and biology (evolution). The God theory becomes a bit easier to accept XD

Transparent cells grew to protect the eye from infection over how many millenia during which time the organisms all died from infection before they were able to get those transparent cells.
It presumes that Evolution again says: Oh hey this is what we need - let's grow this.
Doesn't happen. Unless it comes WITH the creature it goes without it.

Now that's just eyes and This video doesn't make any sense. How many nocturnal animals would prefer to hunt at night. So it's not just about light. How about ears, digestive system, reproduction system, nerve syste, neuron system, etc etc and all of these systems come together with one goal. formed a human. Laughable

How can an early lifeform without sensory organs begin to percieve what it couldn't in the first place to even begin to evolve the senses? It's a contradiction that shows these early life forms couldn't have possibly evolved something when it had no idea it was there in the first place.

Fun fact about the human's blind spot. The brain is able to use previous information to patch in the blind spot. You can learn more about this in Subliminal: How Your Unconscious Mind Rules Your Behavior by Leonard Mlodinow

You can read the data of light on your skin, sounds like something similar to how you can see with your skin, and generations of generations used different structures and things in the place of pigments

I made one eye, myself: ) how the heck the eyes desided to be in the scull and not else where? And why two eyes? Wow. TED, please allow people who can think, to participate, please.
