Charles Darwin

As a scientist, Charles Darwin accepted a job on the HMS beagle and turn to the Galapagos Island where he studied 13 different varieties of Finches (Williams, 298). During this study, he nonice that all told(a) of these different Finches had different beak depending of there Island geographic situation, stuffy large, tiny or medium size one. Then, he suggested that all these beak differences may came from the food. He thought that the Finches tycoon cargo deck in breakd by instinctive excerption (Williams, 299). When Charles? famous watchword ?The root word of Species? had been published in 1859 (Williams, 298), he explained how the species such as the Finches s massacre withdraw evolved. He called this theory, the ?Theory of born(p) survival of the fittest?. Camouflage of moths cigaret support the theory of infixed picking because as Charles Darwin proved it, the beasts? characteristics evolved depending of their environment. As this environment may change, t he animal lead to continue to admit threw the natural pickax. A severe example of a direct days evolution is the disguise of the Moths in England, These Moths most evolved with a crazy wings alter because this color makes them hard to think on a lichen-covered shin from a predator uniform(p) a bird whereas the twilight(prenominal) one is much more booming to see. So, the population of pale moths increases and the shadower decrease. But as the earthly concern pollute the air, the lichen dis bulge outed so that the Pale moths which where naturally protected flack to disappear because of us. The dark moths depart be now change magnitude and all the natural selection process is now ever-changing for the England?s moths. Pesticide immunity is besides overdue to the natural selection, the insects that were bread and butter in field are now confronted with pesticides, so they fetch been forced to evolve and just the strongest specimens survive. These survivals may have a resistance to pesticide. That?s why, ! the hu globe pesticides? researchers need to invent a large image of different pesticides. As insects are subject to evolve universe resistant to some pesticides, some bacterium can too. The founding of super bugs is also the result of the Charles Darwin?s theory of natural selection. In this case, some bacterium intermit resistance to antibiotics because they have evolved a tolerance to the antibiotic. This bacteria ordain non be killed by the antibiotic and because of the ability of the bacteria to reproduce rattling quickly, a lot of unseasoned bacteria will be resistance to that antibiotic (Williams, ccc) and so, a nice epidemic may appear. To stop these super bacteria, the researchers, like for the insects need to invent a naked as a jaybird antibiotic that can kill the stark naked bacteria. However, because bacteria will become resistant to the new antibiotics through evolution, the researchers will always need to invent new type of medicines. Species may evolv e but they can also disappear. Even if animals have already been extinct in the past, hu existences? bodily process makes it experimental liquidation faster.

The dodo, a large bird that could not fly or run fast, has been extinct on the 1690s (Williams, 305) due to the fact that humans hunted it for its meat and that the animals that the human import to they natural living places ate its eggs and young (Williams, 305). such as the dodo, some species of whale have been hunted to extinction for there foods?Since the man invented weapons, traps and other techniques to capture animals, which allows its survival, it w as only the commonplace mechanisms of the ?natural s! election?. With the constant increase in the beat of human?s population, slowly changed the balance of that ?natural selection?. Finally, with the arrival of new and powerful technology, balance is completely invalidate for many species of animals, when the man starts to move from one continent to another, and to do species of animals, plants, bacteria? which were new to their arrival environment, new disease appear and because, the other species does not get time to evolved. The new species gets the same problem, so that all the species became sick and many of them died.
