Not sure about your state (or how you feel about John Oliver), but this clip discusses lottery (on which I also spend the occasional buck). Some talk about funds and education begins at around 10:20. (And it's not quite offtopic - evolution is mentioned in it, too! :-P)

I missed the evolution part.

Didn't realize That much money was spent on the Lottery.....its told right at the start.

YES: very sad to see a gubment pimp its own people into the sham of gambling. It "should be" legal....but NOT PROMOTED. Its touted to support education but actually used as much for tax cuts for the AlreadyTooRich. Just bad gubment all around.

It should have many more lower prizes and very few mega millions. Spread the wealth as much as you can. I'd say 100K max.

Weird but true. It makes sense. Underwater, fish feel vibrations (noise) in their jaw. The brain pathways to interpret that noise evolved then. Rather than evolve a new neural pathway it was simpler for that rear jaw to evolve into something more efficient in shape.

I thought this happened when old world fish evolved into amphibians but I was wrong.


Scientists had thought the evolutionary change occurred after animals had established themselves on land, but a new look at an old fossil suggests ear development was set into motion before any creatures crawled out of the water.

I would put $2 into a pinball table and, with luck, get one replay. That was fun and enjoyable for five minutes. If a person puts $5 on a horse or into a jackpot and gets enjoyment out of that, for five minutes, with little expectation of winning, then I think it's like playing a game of pinball. It's not a big problem. I think it's only a problem when you start betting in large amounts. :D

This is what I'm trying to say, and why I mentioned that really bad Star Trek episode: Evolution does not have an end goal or a conscious intent. In fact, if it did, there wouldn't be speciation in the way we see -- groups of, for instance, monkeys that became separated by distance would continue to "evolve in the same direction", and if they met up again after a million years, both populations would have evolved into the same new species and would be able to interbreed. Instead, what happens is that separated populations evolve differently because there is no pre-set plan in place for them to evolve into the so-called "next stage of evolution" (another example of poor understanding of evolution, straight out of not only Hollywood [the X-Men franchise], but also from someone who put the words into the mouth of Stephen Hawking).

human evolution of the eye -

hunters / warriors , - excellent eyesight .

foragers / farmers / laborers / slaves , - near sighted / poor eyesight .

2 distinct types of humons

Massive generalisation and massively wrong. I suggest you try foraging and see (sic) how far you get with poor eyesight.

I've come up with a set of rules that describe our reactions to technologies:
Spoiler:
1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works.
2. Anything that's invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.
3. Anything invented after you're thirty-five is against the natural order of things.

"distinct" is not generalizing. And people hunted when they couldn't farm, it's just the way it was.

Actually, IR acceptor.

And some cells got really good at it. They provided that slight advantage that made the eye the thing all the cool kids had to have.

The simplest 'eye' is a single protein molecule. Certain proteins, like rhodopsin, respond to the impact of a photon of light by emitting an electron, which can in turn generate a chemical reaction inside a cell. Bacteria have numerous proteins that are very similar to these light sensitive ones. A minor mutation will convert a protein into a light sensitive molecule. When a new protein appears, sensitive to light, it permits the bacterium to detect the direction light is coming from, and orient itself accordingly. This becomes a selective advantage, which preserves the light sensitivity through evolution. Thus, the first 'eye' appears.

Hell, we have plants that will follow the sun across the sky. I don't know why Christers make such a fuss about this.

Plants facing the sun is a somewhat different kind of sensitivity. The sunlight triggers growth inhibitors, which the shady side of the plant has less of because of imperfect transference. The shady side grows slightly faster, bending the plant toward the sun.

Rhodopsin is rhodospin: the molecule is nearly identical whether it is in bacteria, plants or animals, fungi and algae.
Different organisms have modified signalling pathways and modified versions of it, but the principle is always the same.

What the organism does with the information is a completely different question.
