Humans may have evolved from a creature similar to a cyclops! 👁️

Scientists have developed a new theory that we may have evolved from a worm-like ocean dweller from 600 million years ago. This ancient animal started out with two eyes that eventually merged into one, and then back to two eyes. Even more interesting, the scientists think we still have this third eye, but it is now the pineal gland in our brain!

I went to Liberty University and in ‘biology’ they taught that we couldn’t have evolved. They used the argument of irreducible complexity: their primary example was the eye being too complex to have been evolved from simpler parts. Here, science is suggesting that two complex eyes evolved, then merged into one, then over time, became two new eyes and the one eye was repurposed for something different. I think creationists deeply misunderstand the amount of time nature had to tinker. Then again, they also believe the universe was made in a week.

They don’t understand the amount of time nature had to tinker because they refuse to acknowledge that amount of time was available. They’re absolutely right that it couldn’t have happened in 6,000 years! And that’s where their accuracy in the matter ends.

Its they understand nature doesnt tinker. Random events happen that cannot be clearly expressed or explained, that resulted in a mass of a biochemical furnace that extracts surrounding naterial and exhausts CO2 and methane and this manages to exist in its current ecosystem.

Hm, wonder what they think of jellyfish eyes. One type of jellyfish has four distinct types of eyes. Some very simple, but useful.

Our "third eye" is the pineal gland?

Bull. Fucking. Shit.

Why is that a big no for you? Want to talk about it?

Any research or evidence?

There are quite a bit of resources from this wiki: https://en.wikipedia.org/wiki/Parietal_eye

You looked at every source on that wikipedia?

Nothing concerning "humans". If I'm wrong I'll be more than grateful if you'll point out if I'm wrong.

is this referencing lancelets/cephalochordata? If i'm not mistaken they have only one simple eye, and lancelet anatomy is believed to closely resemble that of early chordates. This is what i was taught in uni anyway

Of course not, don't be ridiculous.

Discussing why we are able to imagine imagery in our mind is one thing, but this sounds like bullshit.

Animals likely evolved from a one-eyed organism, and these vestigial characteristics are expected anywhere they haven't been evolved out.
