Evolution Questions: Part 2

Here I finally get to some of the questions, and some more incessant rambling. Sorry, the whole putting my thoughts into organized format for video is new to me.

just type the questions on the box on the side or else we have to watch the videos again

Good idea.. will do.

2E. Gliding helped them get to branches farther than they could if they did not glide, better flaps made them get food first, and the ones with smaller flaps didn't reproduce, or their offspring died, ending their line. scales being a certain way helped them glide also, and just as the flaps, those with more effective traits were perpetuated.

continued change needed, I believe this was in my [2] answer

You don't have extra arms because you can survive without them, and so could your ancestors

2D. Fins. single celled organisms moved around by sort of wiggling, certain shapes would make wiggling more effective, the effective traits of those shapes became more prominent. You'd probably be better reading a book or article about this one, I know I've seen some before, but you get the idea.

there are articles about birds too, probably better than me, but evidence points to bird evolving from tree dwelling dinosaurs which had flaps of skin which helped them glide and you know the rest

2C. As species find food and reproduce, they spread out to new areas with food and whatever else they need. Eventually this path led to the shore line which likely had plants growing on the edges of it. As they graized on the shore line plants. the ability to wriggle up to get the ones further from the water became useful. By this point, they had fins. the more their fins resembled legs, the easier they got food, or took food before their minorly inferior brethren.

@KevinLounsberry 2B. In reproduction, there is also an element of chance for what traits an organism will get from the ones it came from, which is how certain new traits are able to come about, however faint they may be at their start. It's not that the changes were needed. It's that the life forms unfit to live long enough to reproduce, died before they reproduced, and only the life forms who COULD do that, did, and so their traits were perpetuated and it just went on that way.

2. Now we're on to the basics of natural selection. First of all, the environment is always changing and not just from the seasons, so naturally some organisms would need to adapt to that. But also, life needs to consume in order to survive, there is not an infinite supply of the resources it consumes and so unless it is better at consuming them than the other organisms, it won't be around long enough to reproduce. This leaves (mostly) justthe perfectly suited life forms to reproduce.

It is hypothesized that dimensions always existed and they collided and formed our universe as we perceive it. In other words, the speck wasn't always there. it is however unable to be actually studied at this point in time. Either way I think there must have always been something. It just doesn't seem reasonable that a fully sentient all powerful entity would have come before whatever basic "material" it would be made of.

[banditski]

To your first two questions: Where did the speck that everything came from come from and what set it into motion?

Answer is we don't know. The same way people 500 years ago didn't know why people got sick (i.e. they didn't know about bacteria and virii). That's not to say that we will never know where the universe came from, but at this point we only have long shot theories.

But this has nothing to do with evolution. This is cosmology and evolution is biology.

Lol.. make that 'little dinosaur'. Anyway.. presumably it would be small & relatively light.

That's just one idea though.. who knows. maybe trees were involved.

[neuronstorm]

I agree, stages of evolution leading to flight are a bit tricky to imagine. Think of a steep mountainside with little cliffs. The little mammal with more 'fluffy' stuff (originally for warmth) might fall a bit slower due to air resistance, and be more cushioned - so it would 'dare' to jump off slightly bigger rocks to escape a predator. It's an intermediate stage that has an advantage. (not saying that's the exact way it happened - but plausible)

[neuronstorm]

The move from liquid to land makes sense. Every space is fiercely competitive. A fish that could flip onto the mud to temporarily evade a bigger fish or take a bite of food the other fish can't reach would have an advantage. One that could survive out of water a few seconds longer might also be better at escaping predators. lots & lots of very little steps.
