1 From Darwin to Darwin (The Voyage of HMS Beagle) (part 4)
2 THE INFLUENCES Darwin s education was free from any kind of dogmas, both religious and philosophycal. That s why he was able to easily understand all the novelties presented according to the experimental method.
3 THE INFLUENCES The following two essays influenced Darwin s thought very deeply: 1. An Essay on the Principle of Population (written by Thomas Malthus in 1798); 2. Principles of geology (volume 1 & 2, written by Charles Lyell from 1830 to 1833).
4 Principles of geology Sir Charles Lyell ( ) wrote, from 1830 to 1833, Principles of geology, (in two volumes, I & II) which popularised James Hutton's concepts of uniformitarianism, the idea that the Earth was shaped by the same processes still in operation today.
5 THE UNIFORMITARIANISM Unknown forces shape the Earth, year after year, and these forces are always the same while the Earth changes. (UNIFORMITARIANISM)
6 Thomas Robert Malthus ( ) In 1838, Darwin read An Essay on the Principle of Population (published in 1798), written by the economist Thomas R. Malthus
7 relationship food/consumer arithmetic progression geometrical progression X = generation Y = numerical value According to Malthus, food tends to grow in an arithmetic progression, while consumers tends to grow in a geometric progression.
8 Malthus s study about populations An arithmetic progression is a series of numbers that grows by adding a constant value to the initial value (N + K), i.e: 2, 4, 6, 8, 10, 12, 14, 16, 18 (where N=2 and K=2); a geometric progression is a series of numbers that grows by multiplying a constant value to the initial value (N x K), i.e: 2, 4, 8, 16, 32, 64, 128, 256 (where N=2 and K=2)
9 The Cycles of Populations from ECO I -Lezione 15C. Soldatini
10 THE DISCOVERY OF DARWIN DURING HIS JOURNEY
11 THE GLYPTODONT Darwin gave this description of glyptodont: "... a large animal covered in bony armour polygonal pieces, much like that of an armadillo
12 THE FINCHES Darwin observed in the Galapagos Islands fifteen different species of finches
13 IN 1836 BACK HOME After completing extensive surveys in South America the HMS Beagle, returned via New Zealand, to Falmouth, in Cornwall, England on 2 October 1836.
14 : 20 years of thinking He studied the work of British farmers, who practiced artificial selection to improve the species to breed,. For example pigeons which in Darwin's time, were thought to be many different varieties or species of bird
15 : 20 years of thinking Short legged sheep known as Ancon sheep are a grouping of sheep with long bodies and very short legs, with crooked fore-legs. The term is generally applied to a line of sheep bred from a single affected Massachusetts lamb born in The breed was artificially selected and maintained for its desirable inability to jump over fences, however it was finally allowed to go extinct in 1876 when it was no longer required.
16 After all these years (from 1836 to 1856), he was forced to publish his essay by friends, students and colleagues such as Alfred Wallace, a good friend of Darwin. THE ORIGIN OF SPECIES (by natural selection)
17 THE ORIGIN OF SPECIES (by natural selection) in seven points 1. All populations tend to grow in geometrical progression (from Malthus); 2. In each generation, however, the number of individuals of a population remains constant (from Malthus); 3. Hence there must be a struggle for survival (from Malthus);
18 THE ORIGIN OF SPECIES (by natural selection) in seven points 4. Within each species there are individual variations that can be inherited (from his research); 5. Some changes are unfavorable and will not bring a benefit to the individual and shall not be transmitted to the descendants (from his research); 6. Other changes may be favorable and help the organism in the fight for survival, and these changes may be transmitted to the descendants (from his research);
19 THE ORIGIN OF SPECIES (by natural selection) in seven points 7. Over time, favourable changes in a species could introduce significant differences into the population. These differences could eventually lead to the evolution of new species from existing ones (his conclusion)
EVOLUTION. Charles Darwin
EVOLUTION Charles Darwin Question for Thought Earth has millions of other kinds of organisms of every imaginable shape, size, and habitat. This variety of living things is called biological diversity.
