Scientists at a congress in Karlsruhe (Germany) in the 1860th year made the decision to call atom the smallest indivisible particle of substance which is the carrier of its chemical properties. Amount of atoms even in the tiniest, almost not distinguishable with the naked eye, a substance sample not just huge – grandiose. And whether it is possible to count somehow how many atoms contain in any given amount of substance?
Natural selection is a process of survival of the organisms which are most adapted for environmental conditions and death unadapted. It is the major driving factor of evolution of all living organisms. To such opening several scientists came almost at the same time: V. Wells, E. Blyth, A. Wallace and Ch. Darwin. The last created the whole theory on the basis of natural selection.
