thank fish for your ears.

Dg, I really think you need to do some reading.

:edit: I feel dumb even for replying to this thread, I don't undersand how you can be serious about this.

Thats not particuarly fair since their arn't any new environments to exploit.

Not true, since humans started mining copper a few plants have adapted to grow on the **** heaps which have much higher coper concentrations than most places and for quite a while where completely barren because the levels where fatally high for plants, although those plants now can't live anywhere where there isn't such high levels of cooper.

Rats have also been selected to have higher tolerances of warfrin, and so need more vitamin K (?) than they used too, there are tones of new environments and lots of new adoptions, just not very obvious ones.


Huzzar for natural selection \o/

Thats hardly developing a new set of organs... is it? ;)

But yes if you are going to be incredibly pedant against my statement... yes evolution does still occur :p ;)

iirc something changed in their metabolism, so they use copper instead of something else, still it's shows adaption nicely :p

But i hate biology biochemistry and anything with bio in it :o
 
So... we got the ears that the fish didn't need, and they turned their ears into gills?

Or something.

:confused:

No.

There has been a very steady progression of ear evolution from its origins in fish. The evolution of the ear is by far the most interesting in the reptiles (one of my dissertations was on it :p).

I'm not really sure how that links with the gills at all. There probably is one if you squint hard enough.
 
I was thinking if humans never did become the self aware, technology building species we are now I wonder what other species might have evolved to what we are now?

I doubt any other species other than something of primate decent could. Our intelligence is based on the complex set of factors which influence primate social structure, which is totally unseen in the rest of the animal kingdom.

Factors include coalations, infanticide, sexual dimorphism, food distrabution.. etc and the subsequent social interactions needed to increase life reproductive sucess. Unless there was another group which experienced such a set of factors, there would be no reason for that intelligence to evolve.

it wasnt meant to be linked to it.what might be linked was if we have already evolved from fish maybe we will get gills.in order to get gills there must be a very significant change to how we live.this change might happen in the future but would take something of a great magnitude to force us to abandon land.it is all theory at end of day as we wont live the time it takes to achieve such a evolutionary step in mankind, but it is possible.who would have thought we have had to thank fish for our ears.

Problem is if we moved into the sea we'd live in boats and under/over water complexes, not actually just swimming in the sea...

You're actually serious about this? The evolution of ears began with a creature which doesn't even have them and never did? :confused:
