Why There Are Two Sexes

RAZD,I am not knowledgeable in the field of population genetics to judge correctness of Vigen Geodakyan’s theories.More than 25 years ago, I first read the popular article (brilliantly written, but unfortunately not translated to Enflish)
SHE and HE
and later following few of Geodakyan’s scientific publications, I was impressed with the clarity of his thinking, elegance, simplicity a boldness of his prediction.One example of his idea from onother popular magazine
WHY TWO SEXES?“ . A good sculptor, before making a sculpture out of marble, will create many models out of clay. Nature acts similarly. Like a sculptor, nature first creates a large variety of males (clay models), testing them and selecting good variants to implement later in females (marble sculpture). Thus, in a population, new qualities first appear among the males and may afterward appear among the females . ”
. Thus, if the male and the female are distinct from each other in some quality, say in the height or color, one may predict the direction of change; namely, the quality is changing in the direction from the female to the male. For example, if males are bigger than the females, then there is an evolutionary tendency for size to increase in the species. In the other case, if males are smaller than females, the species evolves to have smaller specimens.
We may conjecture that humans are becoming taller at this stage of history, because an average man is taller than an average woman (Fig. 5). Among the spiders, the tendency must be opposite, because their males are smaller than the females. The anthropologists and entomologists believe this is the case: mankind is growing . “Based on his theory Vigen Geodakyan’s predicted the distribution of the gender related diseases that, as I understood, were conformed later by other authors.Bur again, I never followed closely this sorts of research, because I was interested in the most general aspects of biological system development only and was just temporarily diverted from my main subject. Also I am opposing indiscriminate use of methodology of Supreme Purpose that Vigen Geodakyan’s employed at full extend. Yes, they are the same links as in the PO (just reminder, PO itself not the same as an essay). Depending of the preferred level of discussion, you may want to read the essay “Why There Are Two Sexes” or more expended and formal its version “DNA asymmetric gene activity”. My theoretical model also expects that in some circumstances, more that two sexes may exist (more than one cell merging process, but didn't try to find them, but keep focus on the most typical cases. Can you present your examples? I do not know if you can follow the sexual development described in my hypothesis without understanding the proposed mechanism of cell differentiation?Edited by miosim, : No reason given.Edited by AdminModulous, : fixed urlsEdited by miosim, : No reason given.

Sorry RASD,I thought it is readable enough, but any way, I am repeating the portion that relates to the links.More than 25 years ago, I first read the popular article (brilliantly written, but unfortunately not translated to English) SHE and HE and later following few of Geodakyan’s scientific publications, I was impressed with the clarity of his thinking, elegance, simplicity and the boldness of his predictions. One example of his idea from another popular article

M, please do as RAZD suggests and format your links.

The links in Message 16.

Is it still problem with the link? It could be that your request and my action happened in the same time.

Much betterer. Thanks.

Thanks miosim for the reformatting. I use OpenOffice Suite - it reads MS documents just fine without lining Bill Gate's pockets. It's not the population genetics that I have a problem with (yet), rather it is the unfounded assertions and blatant falsehoods. One that struck me was this one:

quote:

---

Much more important is the qualitative feature: in the asexual method no new quality appears, whereas in each instance of the sexual reproduction new qualities appear which are different from the parental ones.

---

This is just plain false. Mutations occur in both asexual and sexual species and copy errors during cell reproduction also occur in both kinds of organisms. Sorry. That's
See Cope's rule

quote:

---

In evolutionary biology, Cope's rule states that population lineages tend to increase body size over geological time.

---

Also, I notice a dearth of evidence that would validate his points. To prove his point he would need to show actual examples of compliance with Cope's Rule and that all the species involved had larger males than females, AND that counter examples to Cope's Rule all involved species with smaller males than females. The problem is that many species are the same size between males and females yet they will increase or decrease in body size over time in response to ecological constraints. Due to better nutrition and health, and they went through a period in the middle of the dark ages when they were smaller than modern humans and smaller than Romans, yet the females are consistently smaller than the males (it's called sexual dimorphism). Yet you use arguments based on it? Arguments that are invalid? You need a better source of information.Enjoy.Edited by RAZD, : added to quotes

RASD,So, the quote below (even this is a middle school level biology) struck you ... ...because you think ... ... even mutations have no relevance to above quote.And then you reject this: Because of quote from Wickipedia: while the complete quote is: I am confused, probably because I do not have the solid foundation in Biology. If you found that Geodakyan’s theory is false, it is fine with me. I have no intention to study Geodakyan’s theories in detailes to defend him.Now I’m looking forward to hear your criticism about my hypothesis.Edited by miosim, : No reason given.

Two words.Antibiotic. Resistance.

This is clearly untrue.An allele that is present on one strand and not on the other is expressed.

molbiogirl,Thank you for this crush course.

molbiogirl,
I do not see contradiction between me and you. Can you please clarify.

If an allele (a gene) is present on one strand of DNA and not on the other strand of DNA, that gene can be expressed phenotypically.For example, if one inherits an A allele from one parent and a B allele from the other, then your blood type will be AB, because both alleles are expressed.
