Egy remek részlet, amit tananyagelemként kiválóan tudnék használni:
Second, it's more accurate to think of natural selection as a process rather than as a guiding hand. Natural selection is the simple result of variation, differential reproduction, and heredity — it is mindless and mechanistic. It has no goals; it's not striving to produce "progress" or a balanced ecosystem.
This is why "need," "try," and "want" are not very accurate words when it comes to explaining evolution. The population or individual does not "want" or "try" to evolve, and natural selection cannot try to supply what an organism "needs." Natural selection just selects among whatever variations exist in the population. The result is evolution.
Evolution does not work this way.
(Understanding Evolution tananyaga, Berkeley)
Persze NEM a természetes szelekció szelektál, ha a szerzők ajánlását követve folyamatnak tekintjük (egyetértek) és nem erőnek, hanem a környezet. Azaz végül csak a kép marad, meg a gondolat....
