Evolution: the Facts.

[Dr Adequate]

Example 5 added to [swiki]Beneficial_Mutations[/swiki]

Cool. Have tidied it up slightly. There was one sentence I didn't understand at all, where you suggested that this was unexplained by established evolutionary principles --- whereas I could think of two explanations, one of which turned out to be right. I snipped that sentence.

Must have been poor wording on my part.
I meant that a diverse population possesses an evolutionary advantage, and is a trait that would be selected for.

No, actually, looking at what you wrote, it was dribbling incomprehension on my part. Oopsie.

 

[Dr Adequate]

OK, I added a piece on [swiki]Metamorphic Rocks[/swiki]. End of Part I.

Part II will be on surface processes, Part III will be on tectonic processes, and then in Part IV I'll get on to stratigraphy and dating and it'll start to look relevant to evolution.

 

[Dr Adequate]

Oh, and here's an interesting article about the fossil discovery of a pregnant early whale.

Cheers, most excellent link.

Regional metamorphism is caused by tectonic events involving both heat and pressure, and will affect large, elongated regions of rock.

The cat in me asks: why elongated?

 

[Dr Adequate]

And a bit of geological creationism-debunking.

[swiki]Lord Kelvin's Blunder[/swiki].

 

[Dr Adequate]

The cat in me asks: why elongated?

Presumably, because such tectonic events are caused by two tectonic plates pushing against one another, and they meet along a line.

I shall see if I can check that explanation, bur it makes sense. to me.

And even with Lord Kelvin not knowing about radioactivity, the Earth was still far too old for YECs...

Yes, but you see Kelvin only provided a maximum age for life on Earth and rock formation. If this is too recent for evolution and geological processes to have taken place, then score one for the creationists.

But the YECs don't then have to suppose that the Earth is that old, and that God made the world at melting point; they are free to imagine that he magicked it into existence just a little way above thermodynamic equilibrium.

I'm not sure that they understand this themselves (understanding things not being their forte) but such is the case.

 

[Dr Adequate]

Okay, on to the surface processes.

Dr. A, do you (or anyone else here) know anything deeper on this item?

The paper's here if you've got access.

Explained here:

The diagram seems to have two numbers on the lineage from Concestor(Macaque, Huuman) to Concestor(OrangUtan, Human). I'm not sure what they mean?

Neat picture.

 

[arthwollipot]

Neat picture.

Oh, that is good.

 

[UnrepentantSinner]

I'm thinking, in light of the "not evolved" thread that we need an entry of for falsification.

We have.

We have.

Heh. And D'oh!

If I can remember my login I'll edit in my list of potential falsifications in the next few days and we'll see how they are received.
