I listened to the video, thanks.
Repay the favor and carefully read the page at this link:
Sandwalk: A chemist who doesn't understand evolution
I was shaking my head as I read this person's comments.
Obviously he does not understand what Tour is saying, and perhaps needs to be more open-minded, rather than one-sided.
I stopped reading when I got here.
Does he really mean to imply that all chemists are "bewildered" about evolution? Does he really think that evolutionary biologists are obliged to supply "chemical details" proving that whales evolved from land animals or that humans and chimpanzees share a common ancestor? Are all chemists this stupid?
What is a mechanism?
I'm sure Tour had this in mind.
mechanism - a natural or established process by which something takes place or is brought about.
Is he asking for chemical details? How utterly ridiculous to think that imo.
I suggest if one really want to understand Tour's position, they listen to his seminar, unless one has the same thinking as this individual. If that's the case, then I understand that person's position.
As i said to before, persons who constantly resort to name calling demonstrate their level of reason.
Look who he called stupid. Is that how scientist view their collegues, or does this only happen when one doesn't agree with their beliefs? Seems obvious, it is the latter.
Wait. Who is he anyway?
LAURENCE A. MORAN...
Larry Moran is a Professor Emeritus in the Department of Biochemistry at the University of Toronto. You can contact him by looking up his email address on the University of Toronto website.
Hmm... Not even on Wikipedia. Interesting.
All I get on this guy, is that he is a scientist, bookseller, and blogger, that loves debating ID proponents.

I wonder why he didn't take up Tour's challenge to explain the mechanism of macroevolution.
Perhaps, because it might take him millions of years to do so.
Perhaps you might be interested in listening to him. Then I would like to ask a question.
To save time, you can start from 4:00. The previous minutes are a waste of time.
My question is this. What is the minimum definition of evolution? What makes evolutionary biology so complicated and messy? Can a person say they believe in evolution, as defined at its minimum, without believing in macroevolution? How is the minimum definition of evolutionary biology different to evolution as defined
here,. or does it only apply in biology, and what is the difference, if any?
Does this definition in any way involve the phrase - from one common ancestor? How so?
This is what my old dictioinary says.
evolution
1. A process in which something passes by degrees to a different stage (especially a more advanced or mature stage).
2. (biology) the sequence of events involved in the evolutionary development of a species or taxonomic group of organisms.
Origin
Early 17th century: from Latin evolutio(n-) ‘unrolling’, from the verb evolvere (see evolve). Early senses related to movement, first recorded in describing a ‘wheeling’ manoeuvre in the realignment of troops or ships.
Current senses stem from a notion of ‘opening out’, giving rise to the sense ‘development’.

evolution (n.)
1620s, "an opening of what was rolled up," from Latin evolutionem (nominative evolutio) "unrolling (of a book)," noun of action from past participle stem of evolvere "to unroll" (see evolve).
Used in medicine, mathematics, and general writing in various senses including "growth to maturity and development of an individual living thing" (1660s). Modern use in biology, of species, first attested 1832 in works of Scottish geologist Charles Lyell. Charles Darwin used the word in print once only, in the closing paragraph of "The Origin of Species" (1859), and preferred descent with modification, in part because evolution already had been used in the discarded 18c. homunculus theory of embryological development (first proposed under this name by Bonnet, 1762) and in part because it carried a sense of "progress" not present in Darwin's idea.
But Victorian belief in progress prevailed (and the advantages of brevity), and Herbert Spencer and other biologists after Darwin popularized evolution.
evolve | Origin and meaning of evolve by Online Etymology Dictionary
evolve (v.)
1640s, "to unfold, open out, expand," from Latin evolvere "to unroll, roll out, roll forth, unfold," especially of books; figuratively "to make clear, disclose; to produce, develop," from assimilated form of ex "out" (see ex-) + volvere "to roll," from PIE root *wel- (3) "to turn, revolve." Meaning "to develop by natural processes to a higher state" is from 1832. Related: Evolved; evolving.
