So why haven't fish progressed to lungs.

because gills work. with lungs, you can only dive, you can't go under water for long (unless you have massive air storage)

Exactly. So the sea snake has a second rate system. Why would the snake go back to the sea.

 

[Darth Vodka]

Not according to evolution. I think evolution does not account for big jumps.

big jumps? all dogs were wolves 15,000 years ago

to eat and breed

They also take on some oxygen through their skin.

Very small jump

Why not stick to land. All the other elapids have done extremely well on land.

 

[Darth Vodka]

Very small jump

i'd say chicauaus (sp?) and dobermans look pretty different to wolves in the blink of eye in evolutionary terms...

if humans dies out tmr, the dingoes in Australia would speciate away from other dogs and wolves very quickly

evolution doesn't let you jump from a to b without an intermediate stage, but some things may still happen very quickly, especially if there is a positive feedback loop

as for the debate between gradual and puntuated equilibria, it's on going and nobody in the debate doubts evolution itself

obviously, at the time, it was an untapped resource (Stifler quote!)

they have done extremely well too, they're still around aren't they?

 

[Rabbie]

no it doesn't

It does according to my wife's embryology book. She is a qualified vet and they use human text books for some of their course. Also see this link

indeed, but there's plenty that would invalidate the theory, that's the definition of a good theory. human fossils before the KT boundary would shake biology to its foundations

It would indeed. But the oldest hominoid fossils are less than 8 million years old.

they had to learn to swim during the flood

But the changes are not really that great. It does not represent the total change that lizard to snake represents where the whole jaw structure changes.

But no need to go there and suffer all the initial problems and that is especially the case for reptiles. For example, reptiles will automatically adjust their size to suit the environment/climate.

 

[Mike375]

What about the land snakes, they are the vast majority of snake species.

 

[Darth Vodka]

It does according to my wife's embryology book

it's a widely repeated myth, widely repeated even in text books

you and your snakes

 

[Mike375]

you and your snakes

OK, what about theropod to bird.

 

[Mike375]

you and your snakes

I should only find ones that easily fit evolution. I forgot you blokes were the counterpart of the bible thumpers

 

[Darth Vodka]

OK, what about theropod to bird.

that's just an empty sentence and all your previous arguments seem to revolve around personal incredulity
