nothing about recombination it is ridiculous that all focus is dedicated on how animals select a partner that in kb text we cannot even afford a note on why do they do that in the first place ok male expose higher mutation rate and thus expose higher variability most of the men are defected whereas others are extremely cute they can spread they genes as hell and best features can be conserved in women who undergo much less mutation and exist solely to conserve best genes best trials aka best men this was said in the article albeit not pronounced clearly better exposition of this part would shed some light on why do we have men and women in the first place it would be even better to say something about recombination recombination aka sexual reproduction or crossover is what allows to combine best features from different individuals it makes evolution much faster than single individual mutation just imagine one guy fortunately acquires one feature another guy acquires another feature third guy acquires some another feature now if they cannot recombine and exchange their knowledge they have to discover everything themselves on the other hand if you have an apple and i have an apple and we exchange these apples then you and i will still each have one apple but if you have an idea and i have an idea and we exchange these ideas then each of us will have two ideas bernard shaw explains the recombination principle the human culture has advanced so rapidly just because you could spread the knowledge for free i am not talking about climate in wikipedia imagine that you had to discover everything yourself you would still live in a cave age so recombination sexual reproduction is extreemly powerful the flirt affairs sucked around is not as closely crucial why cannot we have even a reference to the recombination
