Abstract

Charles Darwin, britanski znanstvenik, postavio je u 19. stoljeću temelje modernoj teoriji
evolucije koja objašnjava postanak vrsta i organizama prirodnom selekcijom. Darvinizam
objašnjava kako opstanak vrsta ovisi o njihovoj sposobnosti prilagođavanja te evoluiranja
kako bi preživjeli. Prirodna selekcija djeluje isključivo na očuvanju i akumulaciji varijacija koje
su korisne u uvjetima kojima je živo biće izloženo. Objašnjava koncept preživljavanja
najsposobnijih te dovodi do promjena u ravnoteži gena. Krajnji rezultat je da svako stvorenje
teži postati bolje u odnosu na njegove uvjete života. Također, razvitkom genetike u 20.
stoljeću, uzgoj životinja olakšan je zahvaljujući brojnim velikim znanstvenicima i njihovim
otkrićima. Selektivni uzgoj doveo je do genetski poboljšanih jedinki i omogućio veću
proizvodnju u gospodarstvu. Materijali će obuhvaćati korištenje iscrpne literature o
pokusima i promatranjima pomoću kojih je došao do koncepta o postanku vrsta.
Sistematskim prikazom alata i metoda kojima su se služili znanstvenici 19.st. objasnit će se
put do zaključaka i otkrića koja nam je predstavio Charles Darwin.

Abstract (english)

Charles Darwin, a British scientist, laid the foundations in the 19th century for a modern
theory of evolution that explains the origin of species and organisms by natural selection.
Darwinism explains that the survival of species depends on their ability to adapt and evolve
in order to survive. Natural selection acts exclusively on the preservation and accumulation
of variations that are useful in the conditions to which the living being is exposed. It explains
the concept of survival of the fittest and leads to changes in gene balance. The end result is
that every creature strives to become better in relation to its living conditions. Also, with the
development of genetics in the 20th century, animal husbandry was facilitated thanks to a
number of great scientists and their discoveries. Selective breeding has led to genetically
improved individuals and enabled higher production in the economy. The materials will
include the use of comprehensive literature of experiments and observations by which he
came up with the concept of the origin of species. A systematic overview of the tools and
methods used by scientists of 19th century will explain the path to conclusions and
discoveries presented to us by Charles Darwin.
