The Cambrian problem

Why do you keep providing me with the coloring book version?

Perhaps because your objections are not exactly sophisticated?

Show me how extremely rare so-called beneficial random mutations can effect the DNA to the point that an echo-location system is derived.

Start with an aquatic mammal that already has functioning echo location -- which is to say, an aquatic mammal. It already produces and stores various oils throughout its body. A single mutation could easily cause exactly the same mechanisms to be triggered in the animal's forehead. If having a layer of oil there improves sound reception at all, then it can be selected for. Subsequent mutations that improve that trait would also be selected for, leading eventually to the dolphin's echo-location melon. Every other part of the system simply needs to be modified from existing structures.

ETA: Oil in the head could also have been beneficial for other reasons -- buoyancy, for example, or oil storage.

Dude, the dolphin doesn't use its ears to hear echolocation....it uses its jaw.

And the vibration is picked up by what part of its body?

Yes, and your post were thoroughly refuted. Or perhaps you can demonstrate how the accustic lens/oil in the forehead already existed in existing mammalian structures.

Since my post on the subject stated explicitly that the melon was a novel structure, I fail to understand how you think you're refuted my post.

As do humans to hear in the water. As you've already been told.

It is impossible for mutations to add up and form new body part, organs or appendages.

Perhaps you can show me wrong an explain how it is possible .

Nonsense of course. You would not think it would take a genius to work out that lots of little changes will eventually produce a big change, but anybody who thought that would have failed to take into account fundamentalists from the American Bible Belt.

It doesn't take a genius to realize that the equation of willy-nilly changes + time = humanity is not only unsupportable scientifically, it's nothing more than a faith-based 'creationist' system.

Coelacanth. Would you like a list of living fossils?

coelacanth isn't a species, it's a group of species that was fairly diverse, and neither modern species appears in the fossil record, want to try again? And even then, a species living till today unchanged doesn't show anything, show a modern species appearing back then, living fossils are species that lived back then that still exist today, show ANY species that evolution says appeared recently back then.

Blah, blah, blah.

You're right! That equation leaves out a very important term, and so requires revision if it is to balance.
Changes+selection+time=new species
Religious "faith" is belief without evidence or even contrary to evidence. (Need I quote scripture?) In science "faith" is belief supported by evidence and reason.

Unfortunately, the single life form to humanity Darwinist 'creationist' view is nothing more than a faith-based view.

Time to click the ignore button, I think.

Could be. Closing your eyes and ears doesn't mean your failure will go away though.

It is more the issue of trying to teach a brick to think. It is futile.

And still nothing but insults. Continue with your pattern of failure.

I'm getting so tired of the comic book version of evolution. Claiming this can happen or that can happen without providing a suitable means is not an answer.

What's new? A bigger head? I can mate two dogs and get that.

Read the entire article.

They developed cecal valves, special muscles that helped their digestion. An organ that wasn't there before.
