Non-replies

Emanuela Solano has not replied on question whether mice with different caryotypes have been observed to interbreed, which I sent her after reading link in "Speciation observed, but not in mammals". Ian Johnston has not replied to my argument immediately below the quote.

I have given both the opportunity to do so, by mailing them.

UPDATE: included in this post among these on this blog which was made to include it and other related posts.

Vatican Conference commemorating Darwin's book - furthering the policy of non-replies towards any creationist challenge.

A reverend admitting that his classification of other people makes dialogue difficult:

"We think that it's not a scientific perspective, nor a theological or philosophical one," said the Rev. Marc Leclerc, the conference director and a professor of philosophy of nature at the Gregorian. "This makes a dialogue very difficult, maybe impossible."

Let us put things clear:

a) being creationist in observance of literal meaning of Genesis ch. 1 & 2, or of St Paul who said "by the sin of one man, death entered the world" is clearly a theological perspective - just as much as theistic evolution is theological in Theilhard de Chardin and his "point Omega";

b) accepting Intelligent Design as the only intelligent and coherent explanation of complex systems with simple and obviously good functions (eye is complex, sight as we experience it is simple), or at least far superior to atheistic and materialistic evolution is, for both creationists and theistic evolutionists (it excludes neither) a philosophical perspective, at least as much as atheistic and materialistic versions of darwinism;

c) criticising radioactivity based datings, the missing of transitional fossiles - systematic if we are to agree with that chapter of a book from Watchtower Society (I disagree with others), the impossibility or near so of stable chromosome number mutations in mammals (except Richardsonian fusions, maybe) is clearly at least as scientific as not bothering to answer the chromosome problem properly.

And scientific as well as philosophic (epistemologic) is the question admitted even by Darwinists in the Flores Hobbit case:

Chromosomam polymorphism

Hans Lundahl a dit…

Chromosomal, of course

Wiki article, cached 2009-04-16 7:20:43

"In some cases of differing counts, the difference in chromosome counts is the result of a single chromosome undergoing fission, where it splits into two smaller chromosomes, or two undergoing fusion, where two chromosomes join to form one.

This condition has been detected in many species. Trichomycterus davisi, for example, is an extreme case where the polymorphism was present within a single chimeric individual.[1]

It has also been studied in alfalfa,[2] shrews,[3] Brazilian rodents,[4] and an enormous variety of other animals and plants.[5]"

Note five goes to a google search where many links (as of my short specimen taking) are NOT questions of varying chromosome numbers, but only of various chromosome lengths on this or that chromosome.

Brazilian rodents are a bit like mice. Shrews and alfalfa are clearly not mammals and therefore irrelevant for my problem.

Robertsonian fusions occur in Nucella lapillus - which is not a mammal

the fusions are of course Robertsonian, not Richardsonian, as I wrongly wrote on previous comment

Hans Lundahl a dit…

Owl monkeys (Aotus) seem to have different chromosome numbers. Mammals, not rodents but primates.

Hans Lundahl a dit…

This article says that Robertsonian translocation/Homologous fission is seen in diverse species of equus - but the abstract does not explain how that is supposed to work.

This article on American Negro and White populations concerns chromosome lengths, not numbers.

This scholar Google has been further narrowed down to recent articles:

I have also taken away species already commented on, I have also taken away some species clearly not mammal (plants, fish, birds).

Here's the top article - chromosome polymorphisms cause reproductional abnormalities.

Hans Lundahl a dit…

The article on South American deer promises evolutionary history ... but are the polymorphisms seen in genesi or after the supposed events?

Quoting which:

"Using G-banding and deleting the heterochromatic short arms, the chromosomes of the African Green monkey can be artificially fused to reconstruct a karyotype of the Rhesus with only one pair of unmatched small metacentrics."
