POLL - Should I doubt EVOLUTION now? Are my second thoughts valid?

Of course it's true that Chimpanzee DNA is extremely close to ours, Horses are not so close to us, Sharks are quite distant from us, Insects are extremely distant in terms of DNA and so on. Microevolution has even been demonstrated, such as various dog breeds.

But...

They say that our homo sapien species came under 1 million years ago, and the homo genus itself came just under 3 million years ago after evolving from primates. They say that evolution keeps happening all the time... it's a natural selection process. It just HAS to happen. But there's no explaination for current species that haven't evolved AT ALL for hundreds of millions of years? WTF? For example:

- Coelacanth 400 million years
- Tuatara 200 mya
- Horseshoe crab 200 mya
- Crocodiles 140 mya
- Chinese Giant Salamander 170 mya
- Neopilina Molluscs 500 mya

So these guys (among others) stay the EXACT same way for such a long time, but we changed rapidly so many times in just 3 million years?

So maybe we've also been there since forever and these other fossils are just extinct primates (we didn't evolve from them)?

So basically, these living fossils are extremely well adapted to their environment?

That's pretty strange, there are soooooo many other species who live in the exact same environment, do well and they have seemingly still evolved!!

Why have we evolved so many times in just 3 million years, which is 100 times less... when we were the best surviving and "fittest" species on the planet?

  • My eyes hurt, so I can't give a good answer because I can't read your entire question-but I want to drop an opinion so I can come back later.
    Intense pressure can cause selection/change to occur more rapidly in a population that say... lives under rocks and never experience much pressure.
    So rapid change is possible just as little to no change is also possible.

  • This is easy: Coelocanths, Crocodiles, Horshoe Crabs, Tuataras etc are NOT specific species but clades of organisms. No species of those clades from the aforementioned times are still alive.
    Here's a species of Coelocanth from 215 mya

      Hmm... but it's still strange that these species are identical to the ones found millions of years ago... they are classified as the same species because of this. I mean, a different species would have different features too right? Why else is the scientific community saying that it's the same?

  • Here's why I doubt evolution from one species to another, it's mathematically impossible. For something to be scientific fact it has to be proven mathematically and so far the theory of evolution hasn't come close.

  • They do not genetically stay the exact same way- only their phenotype does. Because it's the fittest one for their environment and their environment apparently hasn't changed enough to cause them to change, too. When you look into it, it's still logical.

  • Second guessing is never a bad thing. It is how we find flaws or holes in our colecitve knowledge. You should know that before an idea can be considered a scientific theory it has already undergone years of rewriting, scrutiny, and the same experiments and observations done by many other people in the field. More is know about evolution that there is about gravity but nobody ever tries to say gravity is all made up.

    Yes evolution is constantly happening but like any real science it is the study if what is actually going on rather than what we think should be happening. Sure there are predictions about what humans will look like in a few more million years if we don't kill ourselves off first. Bigger eyes, less hair, bugger brains... But that is just looking at our ancestors and taking the same changes further.

    As for why some things haven't changed much. The simple answer is that they haven't needed too. Every animal takes up a ecological niche and will stay there if they don't have any reason to move. 65 million years ago there was a mass extinction that left huge room for new animals (primarily mammals) to inte new niches. Think of it this way, if you have a decent job that pays well enough to support your family and has good security why leave it. Then your boss decides to retire, you are going to try and get that job aren't you? Or how about this one, you loose your job for whatever reason but still have to support your family so you need to develop new skills and find a new job in order to do so. In this metaphor "you" are the species not an individual.

    • Every single species is a link between what came before and after it. Unless of course that branch of the tree ended with extinction.

      I think "chink in the armor" is an inappropriate term here. Evolution isn't trying to define anything, only trying to study what is there. Are there gaps in the information? Absolutely, and there always will be. There are and estimated 87% of unidentified species alive right now. There is no way in hell we will ever find all of the billions upon billions that have already gone extinct.

    • I know what evolution is, don't treat me like a bigoted creationist.

      Evolution is supposed to be true for all species... there are mutations in every 130 replications iirc, so that means macro evolution would take place within a couple of million years. However some species just don't evolve.

      This somewhat weakens the evolution theory at its very core, although the DNA similarities & fossil depths are quite obviously the reason why evolution is the most likely scenario... but there could be some other explaination.

      It is interesting to note that the coelacanth has found to have a vestigial lung :P

  • It's pretty depressing that the poll/answers are not 100% pro evolution. It shows how bad the worlds education systems are these days that a scientific fact well proven countless times is still "not believed." It's not something to doubt or not believe in, it's just a fact that happens.

    • I'm saying evolution is probably the most likely scenario... but this is a bit weird

    • It's not weird if you take every specis on the planet some are going to end up being optimal enough for their environment not to need to evolve

  • Evolution does not occur at a set rate. I'm no biologist, but from what I gather we simply evolve when our environment changes. The planet was barren when the first creatures evolved. They had to be tough. Slowly, the planet becomes more habitable and the necesseties of life become more readily available, so we evolved to the specifics of this new environment.

    All this said, it is the THEORY of evolution. Nobody told you it was a fact. If something is not a fact, then questioning it is good. That is how we progress.

    Evolution doesn't happen at a steady pace, it happens in reaction to changes opportunities etc. The rate of reproduction also matters - viruses and bacteria can evolve faster than we do because of how rapidly 100 generations may pass for them, which means a successful mutation can spread very very rapidly.

  • No, their outward appearance is largely unchanged, we can't ell from the fossil records if they have evolved in other ways.

    Evolution is not always happening, it happens in response to environmental pressure and sometimes do to sexual selection which is like the butterfly effect and can start from a small random variation. No change in the environment means no change. If the environment constrains the population of the organism and doesn't change there will be no evolution or rather any changes will be corrected back to the norm.

    This doesn't happen very often but it happens.

    • Just to give you another example:

      Tadpole shrimps are found as far apart as China and Scotland, and have survived for 300 million years. That means they survived the Permian extinction, often known as the Great Dying, which wiped out almost every other animal species.
