Humanity will kill itself

The basic idea of this thesis is that humanity will destroy itself by developing medicine. Let us focus on the question “how and to what extent the development of medicine will affect the prospects of mankind”. We focus on the fact that the development of medicine contributes to the fact that it significantly reduces the role of negative selection, equalising the chances of reproductive success for all members of the population. Timely rendered medical services allow receiving equal reproductive success simultaneously and representatives with successful mutations and representatives of the population with negative mutations. On the scale of several hundreds or even thousands of years, the absence of the factor of negative selection will inevitably lead to the fact that each next generation will be weaker than the previous one.  The negative mutations will get an equal chance to be fixed in the population as positive ones.
