MACROevolution vs MICROevolution - what is it?

The difference between Florida panther and puma isn't a "basic fundamental error." The terms suggest two different breeds of cat. I don't have the time or the eyesight to research every side issue.

Good post but if you are living you make mistakes. FYI not referencing religous thought.

You aren't making any sense. I said the gene WASN'T lost, I said alleles are lost.

That's because you do not understsnd. Prove genes are lost. You can't skip this point by saying alleles are lost. The alleles are never lost because they are merely a source of reused information, like switches on a page you can read and relay to someone else.Edited by DOCJ, : Err

ALLELES ARE LOST FROM A GIVEN POPULATION WHEN THE GENES ARE HOMOZYGOUS.YOU DON'T KNOW WHAT YOU'RE TALKING ABOUT AND THERE IS NO POINT IN CONTINUING THIS DISCUSSION WITH YOU.

I have brought this up before, but I want to present it here again for your consideration. It is the technique breeders use called recombinant inbred lines (aka. RILs). If your position were true, that it only takes isolation and inbreeding for several generations to produce new species, then RILs should produce numerous new species... but they don't.Here's how it works (this is for organisms that can self-fertilize):1. Two parents of interest, that are usually highly heterogeneous, are interbred and grown to seed.2. A large number of seeds are collected and planted for the next generation (this is called the F₁ generation).3. F₁ plants are selfed (pollen from the same plant is used to fertilize the ovaries) and seeds from each F₁ selfing are collected separately and become the F₂ generation. ** This is the isolation step. From here on out, each independent line is completely isolated from the other lines.4. F₂ plants are selfed and seeds collected separately and become the F₃ generation.5. The process typically continues for 6 - 10 generations and the final generation would be knownas the F_n generation.The image below diagrams the process: ** The process also works for organisms that cannot self-fertilize. In that case siblings from each generation are crossed, as shown above. Animals can be bred in this manner and, for example, is how laboratory mice are produced.The results of this extreme inbreeding is highly homogeneous lines with inbreeding coefficients >.95 and even approaching 1.0 (an inbreeding coefficient of 1.0 would indicate an identical/clonal population). This would mean that if a F₁₀ individual produced 1,000 seeds, the plants that grew from those would be virtually identical genetically - all 1,000 of them. There would be almost no variability in that F₁₀ population. This would be the true "end of evolution by loss of genetic information" that you insist on.RIL populations are usually quite large, containing several hundred individuals (300 is kind of the excepted minimum population size for good statistical power), all with unique, high homogeneous genotypes. Yet none are new species, none are reproductively isolated from the others. Why? There is no more efficient method of partitioning genetic diversity than recombinant inbred lines, it is the most extreme example of isolation, inbreeding and genetic drift (which you refer to as random selection) possible. Why does it not produce new species?Hint: all the genetic material in the parents still exists in the F_n population, but is just distributed among individuals rather than being contained in a single breeding pair. It must take an addition factor to differentiate those individuals into separate species. What could that factor be... maybe m*******? (Thanks to David Jay; this is a great idea to hide letters of a word so that the person you are having a discussion with has to guess what the word might be )I would guess you don't really see the significance of what I presented above, but it demonstrates beyond a reasonable doubt that isolation, inbreeding and genetic drift are not sufficient to produce new species. There must be another factor involved.HBDEdited by herebedragons, : changed sub-title

I'm pretty sure it's you that doesn't understand the difference between a gene and an allele... Source?HBD

Pray tell... what are these 4 types of alleles that exist inside a gene?HBD

Plants can evolve on their own. Much different than animals.😂

Getting through that was a struggle. I'll probably have to do it again.What I want to know right now however, is where's the selection? I don't see any selection. My whole scenario is all about selection. Isolation and inbreeding occur after selection in order to homogenize the new set of gene frequencies brought about by the selection, meaning the reduced number of individuals separated out to be the founders of a daughter population. Your scenario looks like something entirely different, but again, I may have to read it another time.Edited by Faith, : No reason given.

Did you even watch the video you referenced? Not a very technical presentation, but it certainly doesn't say anything about: And I see nothing in the video about drift...Where are you getting your information????HBD

A source. Alleles are switches that are passed down i.e. reused.How Do Alleles Determine Traits in Genetics?

Don't you consider drift to be "random selection"? Only one seed from each cross is used to generate the next generation. That is extreme drift, ie. "random selection".I am pretty sure you don't view selection in the same way the rest of us do. I don't have time now to go back and dig up your statements about selection, but you have previously dismissed the roll of natural selection and put the emphasis on isolation, inbreeding and drift. Maybe you have changed positions and I missed that part of the discussion?So describe how you think the outcome of recombinant inbreeding would be different if at each step you grew up 50 individuals in each line and selected from that 50 an individual for some particular characteristic (each line having a different character selected for).The end result would still be highly homozygous, inbred populations; they would just have selected characters rather random characters. How would it be different?HBD

Recessive traits lead to drift.
