Frequently asked questions
Q: How old is the theory
and where was it first published?
A: The
theory is 40 years old. It was first published in
scientific-popular magazine “Nauka I Zizn”
(“Science and
Life”) in 1965.
Q: How many articles
are published?
A: Since 1965 more than 150 articles were published devoted
to different aspects of sex related questions—longevity,
differentiation of a brain and hands, sex chromosomes,
mechanisms of sex ratio regulation at plants and animals,
heart diseases and other illnesses.
Q: Where the theory
was presented?
A: Was presented at the following international congresses
and symposia:
Symp. Natur. Selection, Liblice, CSAV, Praha, 1978.

Q: Where can I find
more information and publications about the theory?
A: On this site under the “Articles”
tab.
Q: What organisms are covered by the
Evolutionary Theory of
Sex?
A: The
theory applies to plants, animals and humans.
Q: What levels of organization are covered by
the Evolutionary
Theory of
Sex?
A: All
levels of organization can be explained: cell, organ,
population, social and psychological.
Q: What topics or
problems related to sex are covered?
A: How to describe the evolution of a character (to define
the evolutionary direction of any feature, to differentiate
evolving and stable features, to define the current phase of
feature’s evolution process) (all species).
The mechanisms of
Sex Ratio regulation (all species).
The reaction norm.
The evolutionary role of sex chromosomes (all species).
The role of pollen amount in regulating dispersion, sex
ratio and sexual dimorphism of dioecious or cross-pollinated
plants offspring (plants).
The explanation of father’s and mother’s dominant features
of reciprocal hybrids
(animals).
The explanation of congenital malformations of the
heart and major blood vessels (humans).
The explanation of brain asymmetry and handedness (animals and humans).
The explanation of psychological sexual dimorphism (humans).
The explanation of sexual dimorphism in anthropology.
Q: What branches of
science or what specialists can use the theory?
A: Theory can be used as an explanatory and prognostic tool
in biology, genetics, medicine, anthropology, brain research
and psychology.
Q: What phenomena can
be predicted?
A: For the list of predictions click
here.
It was possible to relate together Past and Future
forms of traits in different phenomena such as phylogeny,
ontogeny, sexual dimorphism, dominance, mutation, heterosis,
and reciprocal differences. Any of these phenomena can serve
as a “compass” indicating the direction of the evolution of
a given trait.
Q: What theories can
be replaced as an explanation of general phenomena?
[all theories listed can still be important in order
to explain specific mechanisms]
Evolutionary Theory of Sex
A:
The theory of sexual selection (C. Darwin), the
“Ratchet theory”, R. Fisher—H.T. Müller theory, the “Gene
repair” theory
(R. E. Michod, 1995), the theory of gene imbalance
(Gunter, 1923; Huxley, 1924; Lenz, 1923;
Schirmer, 1929), the
metabolic theory (McArthur and Baillie, 1932), the
“theory of equal expenses” (R. Fisher)
The theories of Congenital Malformations of the Heart and
Major Blood Vessels (Rokitansky, 1875; Spitzer, 1923;
and Krimski, 1963).
Q: What theories
Theory of Asymmetrization of Organisms, Brain and Body can replace?
A:
All theories of
brain
asymmetry,
all theories of left-handedness (The Right Shift Theory M.
Annett, 2002), The
Geschwind-Behan-Galaburda
(GBG) Theory of Left-Handedness
