People are still asking questions:

“Sex represents the most important challenge to the modern theory
of evolution... the queen of problems... the main question is —why sex?”
                                                                                              Bell (1982)

“The “reversed” sexual size dimorphism of predatory birds,
 with females in some cases almost twice as large as males,
 has long puzzled ecologists. ... A review by Mueller and
Meyer (1985) listed twenty hypotheses!”

Are Men Smarter Than Women?                    Are Men Necessary?

 Can you make 4 equilateral triangles with
6 toothpicks (they can't cross each other)?
This is 3-dimensional riddle which can not be
solved in 2-dimensions (tetrahedron)


Likewise, the problems of evolution can not be solved inside non evolutionary branches of science that deal with small time periods. Therefore any attempts to solve riddles of asymmetry from embryology, pathology or the anomalies of development point of view as well as attempts to solve problem of sex as reproductive are destined to failure.

What such different phenomena as female - male sex, right- - left brain hemispheres, right- - left-handed people, DNA - proteins, and autosomes - sex chromosomes have in common?

All of them are 2 forms (phases) created in the process of evolution from their respective unitary systems— population, brain, society etc. Increasing variety of the unitary system elements transforms those systems into binary ones consisting of conservative and operative subsystems. First members (conservative subsystems) of the listed pairs are responsible for the system preservation, second ones (operative subsystems) — for its change.

All biological theories, including main paradigms classical genetics and Darwinism, are by default theories for unitary systems. When these theories attempt to explain behavior of binary systems, they treat their subsystems as different forms, but not as phases, therefore they lack one dimension. This is why we have so many riddles.

This means that the paradigm should be changed.

Increased variety and therefore more close contact of the operative subsystems with the environment transforms monomodal population into bimodal, direct “ecology” (environment system) into indirect one (environment operative conservative subsystem) and synchronous evolution into asynchronous (first operative then conservative subsystems). Appropriate theories are required for their description.

Binary conjugated systems need theories of bimodal populations,
indirect “ecology” and asynchronous evolution
