My education hasnt failed me. I didnt major in biology and didnt take any advanced biology courses. Im not even talking trash. I really want to know how the light sensitive cells idea became eyes comes from. Oh well Ill just wait until i run into a science nerd in real life.
And it shouldnt take a biochemistry class to explain what concrete proof scientist have found that removes all doubt that humans developed sight from a mutation that created photo sensitive proteins
uhh.....yeah it might take a biochem class because I posted videos and lectures and you skipped over those. I've got neuroscience under my belt so tell me where the needs to go, for YOUR sake.
1. there are photon sensitive cells that exist as single cellular organs (look at cyanobacteria)
2. some of these photon sensitive cells initiate metabolic processes that change the membrane potential of cell by altering membrane permeability
3. some of these photon-sensitive cells have been able to localize their effects and effectively (AS A WHOLE) transmit signals to other parts of the body
4. some bacteria can sense environmental conditions and change their behavior. look up chemotaxis
Complicate and refine that process...and voila: the eye.
You know whats also interesting? Its now understood that eyes have developed independently a few times. i.e. the conditions in many niches tend to allow the development of eyes....and environments that
DONT, dont tend to create eyes i.e. the naked mole rat.
Now...we can go further than that if you want, or you can keep pretending like just because YOU odn't know something, that therefore it isn't known.
This isn't controversial.
its proven.
its explained.
I've been telling every one to watch it. Every time it comes on I pee a little.
. I remember someone claiming that Roe vs Wade and abortions reducing unwanted pregnancies was a factor, but that's anecdotal. This would be based on science. Sure enough:
