ACTIVITY Ensure that the Brazilian population grew at PG. Try to find out if food production in Brazil, in the period in question, was in PA. What conclusions can be deduced by analyzing the data of Tables 3 and 4? Assuming that the Brazilian population feeding poorly and that thousands of people do not have the basic food to eat on a day-to-day, it is possible to make a consistent analysis from writing Malthus? The ideas of Malthus, Darwin concluded that some individuals die from lack of food before they reproduce, so there is a fight for survival. Those who were more advantaged have more chances to survive. As is the case with the long neck of the giraffe. With these analyzes, Darwin concluded that changes could occur in the species and that populations could grow very quickly. However this growth is not noticed because populations generally remain in constant balance. So there should be some way to keep that balance. Darwin thus concluded that it was the natural selection of the fittest. DEBATE The great merit of Darwin was to describe how changes could occur in the species. Do you agree with Darwin? Justify. Sometimes we are asking ourselves why certain species are the way they are. Who has not heard the story of why the jabuticaba be a fruit so small a tree as tall and as big pumpkin a fruit of a plant so low? Have you ever wondered, for example, what if the ostrich fly? Now, if this were so, it would need a lot of food to give him energy to move its huge body in the air. To what is observed, it seems that there is a reason for everything, principalmenteno respect to living things are adapted to their environment. Mimicry is an evolutionary adaptation in which the species develops features that overlap with other living beings. In the figure, the genre Kalima moths that look like dried leaves.

AKTIVNOST Osigurati da je brazilska stanovnika rastao PG. pokušati saznati je li proizvodnja hrane u Brazilu, u razdoblju u pitanju, bio je u PA. Koji se zaključci mogu izvesti analizirajući podatke o tablicama 3 i 4? Uz pretpostavku da je brazilska stanovništva hranjenja slabo i da su tisuće ljudi nemaju osnovnu hranu za jesti na dan-to-dan, moguće je napraviti analizu dosljedan od pisanja Malthusa? Ideje Malthusa, Darwin je zaključio da su neki pojedinci umrijeti od nedostatka hrane prije nego što se razmnožavaju, tako da je borba za opstanak. Oni koji su bili u prednosti imaju više šanse da prežive. Kao što je slučaj s dugim vratom žirafe. S tim analizama, Darwin je zaključio da se promjene mogu dogoditi u vrstama i da populacija može rasti vrlo brzo. No taj rast nije primijetio, jer populacija uglavnom ostaju u stalnoj ravnoteži. Dakle, tamo bi trebao biti neki način da bi se taj balans. Darwin je tako zaključio da je to prirodna selekcija od najjačih. DEBATA Velika zasluga Darwin bio je opisati kako se promjene mogu dogoditi u vrsta. Slažete li se s Darwina? Opravdati. Ponekad se pitamo zašto se neke vrste su takve kakve jesu. Tko još nije čuo za priču o tome zašto jabuticaba biti plod tako mali stablo kao visok kao i velikim bundeve plod biljke tako niske? Jeste li se ikada zapitali, primjerice, što ako noja letjeti? Sada, ako je to bilo tako, bilo bi potrebno puno hrane da mu energiju da se presele svoju veliku tijelo u zraku. Za ono što se promatra, čini se da postoji razlog za sve, principalmenteno počast živih bića su prilagođena svojoj okolini. Mimikrija je evolucijska prilagodba u kojem je vrsta razvija značajke koje se preklapaju s drugim živim bićima. Na slici, žanrovski Kalima moljaca koji izgledaju poput suhog lišća.
