Resources on Evolution

[juvenissun]

It was contained in his definition (post #109).

No. That definition is overloaded. I just want to simplify it and make the critical factor explicit. It is the environment which change the direction of evolution.

Correct?

 

[juvenissun]

He wrote a book, the clue is in the title.

What is the title?

 

[Jimmy D]

What is the title?

On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life

 

[Speedwell]

Correct?

Quit playing Socratic dialogue and make your point.

 

[DogmaHunter]

its also true for living creatures. unless you can show me otherwise.

Sure.

Phylogenetic tree - Wikipedia

That's a phylogenetic tree that's been generated by an automated process based on a huge database of fully sequenced genomes of many many species.

It compares genomes and maps out matches.
The pattern in the svg is what pops out.

You can obtain the same tree by tracing specific genes, specific traits, comparative anatomy... it even matches the geographic distribution of species in context of shifting continents in plat tectonics.


Counting down to nonsensical objections exposing further that you don't know what you are talking about in 3....2.....1.....

So evolution is "controlled" by environment. Right?
If so, why not add this critical condition to the definition of evolution?

Ever heared of "natural selection"?

On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life

So you think "natural selection" is the key idea of evolution.
What about the alleles?

 

[Jimmy D]

Yes. Why?

Oh, and thanks for ignoring the latter part of my post. A tacit admission that you were wrong is better than none at all.

My point is not important. What's important is my question.

I picked up the weak point of evolution argument. I told you that is what I am good at.
Evolutionist can not answer my questions.

What I think is "key idea" is irrelevant, I was responding to your question....

"So evolution is "controlled" by environment. Right?

Your question was addressed.... You should be thanking me, not changing the subject.

 

[Speedwell]

My point is not important. What's important is my question.

With each new generation a species presents a range of variant types to the environment. Those variants which are most successful in that environment are more likely to survive and reproduce, passing their variations to their offspring. That is the role the environment plays in evolution.

OK. You did address the question on what is evolution.
Then do you agree that evolution history shows a trend of change based on your understanding of natural selection?

 

[Speedwell]

So you think "natural selection" is the key idea of evolution.
What about the alleles?

The two key ideas of evolution are randomly distributed heritable variation and natural selection.

 

[juvenissun]

Fine.
Then let's see the range and direction of environmental change. Did environmental change go straight forward or go back and forth in the earth history?

 

[juvenissun]

The two key ideas of evolution are randomly distributed heritable variation and natural selection.

Fine, very inclusive. But in terms of the "trend of evolution", they can not go together. And may neither be applied.

Well, it seems that everyone has adequately addressed your questions.

Darwin dedicated large parts of his book to the effects of environmental pressures. I can only assume that you were feigning ignorance when you asked...

"So evolution is "controlled" by environment. Right?
If so, why not add this critical condition to the definition of evolution?"

So what are you "good" at exactly? feigning ignorance, trolling?

What you are not good at is justifying your criticisms of nested hierarchies as evidence of evolution. I notice you have still refused to answer my question.

As I said, I accept your refusal to offer any meaningful response as a tacit admission that you were wrong.

 

[Speedwell]

Fine.
Then let's see the range and direction of environmental change. Did environmental change go straight forward or go back and forth in the earth history?

Evolution goes in the direction of improved adaptation to the existing environment. I'm not sure what you mean by "back and forth" in that context.

 

[Speedwell]

Fine, very inclusive. But in terms of the "trend of evolution", they can not go together. And may neither be applied.

Why not?

 

[46AND2]

So evolution is "controlled" by environment. Right?
If so, why not add this critical condition to the definition of evolution?

I did.

But it is only partly controlled by environment...I listed other mechanisms, too.

When do we get to the hard questions?
