Guests from the Past. Column in KomputerraOnline #52
We are more anachronistic than Rip Van Winkle; we were shaped by long-vanished epochs. Our biological foundation has remained unchanged, while our way of life and our social roles have changed fundamentally.

Congratulations to Olya Mikhailova and Nastya Kechedzhi on winning the competition!
At the All-Ukrainian competition of student research papers in Zaporizhzhia, the work by Olga Mikhailova and Anastasia Kechedzhi on the study of gametogenesis in green frogs took III place. Notably, our works on frogs have been winning places at this …
March 17. Eskhar, Continuation of the Field Season
Last time the frogs were very hard to catch, but we need them for our work. We had to go again. The weather was not much different from last time — only it was cloudier, and the mud on the …
Altruism and Simpson's paradox. Column in ComputerreOnline #50
In different conditions, the greatest success is provided by different behavioral forms – sometimes purely selfish, sometimes antagonistic, but quite often also altruistic.
March 8. Winter Is Over
Snow still lies on the ground, but the sun is melting through it. Above dark objects hidden in the snow (twigs, for example), small windows form from fused ice droplets
“Ecological problems” for university and school students. Column in ComputerreOnline #49
Night, in the distance trout splash. Across the meadow moves a formation of ninety thousand tadpoles, devouring insects. Toward us, under the cover of darkness, a thousand "ecologists" march.
March 4. Eskhar
The start of field season! A short trip to Eskhar, after frogs surviving the cold in the warm water of the power plant discharge.
The wonders of sexual reproduction. Column in ComputerreOnline #48
The mechanisms of gene transmission and alteration differ among asexual species, the parasexual Penicillium, humans and other animals with a typical sexual cycle, and the truly extraordinary Pushtun frogs
When Does Selection Become Ineffective? Column in KomputerraOnline #47
When the fitness of an individual is influenced by the variation of many genes, and especially when the effect of some genes depends on the state of others, the rate of evolution under the Modern Synthesis model drops sharply.

It so happened that conversations about "Valentine's Day" always irritated me considerably. ... I regularly check Google Analytics or Yandex Metrica, tracking how this website "performs." ... The established pattern in visit dynamics was disrupted on New Year's, and, surprisingly …
The paradox of accelerated evolution. Column in ComputerreOnline #46
Could organisms arise in a fluctuating environment whose efficiency of producing new adaptations would be reduced—since they would inevitably be outcompeted by those that evolved more rapidly?
The Difficulties of Career Guidance. Column in KomputerraOnline #45
The most important thing in education is not the diploma, not the status that allows one to hold a certain position, not a specific set of knowledge. The most important thing is the difficult-to-formalise transformation of a person.

Vorontsov, 1999. On the postulates of SET (according to the book 'Development of evolutionary ideas in biology')
In 1978-1980, Mykola Mykolayovych Vorontsov (1934-2000) made an attempt to systematize the main postulates of the STE (synthetic theory of evolution). In his last major work, published in 1999 (Воронцов Н. Н. Развитие эволюционных идей в биологии. М.: Изд. отд. …
