Darwin was in the Galapagos Islands August to September 1834. It was there that he began wondering about evolution. He returned to England in 1836, and in 1837 Darwin started his first notebook on evolution, secretly.

Charles Darwin theory of evolution?

The theory of charles darwin is the theory of evolution it explainsthat species of live evolved from a primitive form by way ofadaptation and natural selection

How did Charles Darwin come up with the idea of evolution?

Charles Darwin went to an island (Galapagos)where he studied the beaks of finches. He noticed that the although the birds were from the same species, they looked different. This is how he worked out that "Species change over time to adapt to their environment."

What is Charles Darwin theory of evolution?

Charles Robert Darwin's theory of evolution was that all varieties of life descended from shared (in common) ancestors. This means more complex creatures naturally evolved from simpler ancestors, over time. In other words more agile or better fit organisms tend to survive and to pass on their superior characteristics to subsequent generations. The theory of evolution consists of two primary rules. One is that replication is imperfect, hence variation is introduced in reproduction. The second is that the environment may act as a sieve to winnow "favorable" traits from those traits conferring no natural advantage. The interplay between these two rules accounts for all the species we find today, and all the fossils of species that ever existed. Indeed, if evolution was right we should expect to be able to categorize life forms into a nested hierarchy based upon the ancestral relationships, and this is what we find. For example, our own species is Homo sapiens . We are catarrhines (narrow-nosed simians), sharing certain attributes with extinct species of other catarrhines such as neandertal and australopithecus . The simians are a subset of haplorhini, or dry-nosed primates, which includes tarsiers. Together with the strepsirrhini the haplorhines form a group known as the primates. Primates include lemurs, lorises, (both of which are strepsirrhines), apes, and us. All primates are euarchonts, which together with the glires (rodents and lagomorphs or "bunnies") form the euarchontoglires. These are eutherians, or placental mammals. Together with the metatherians or marsupials, and the monotremes, these three groups form the mammals. Mammals are characterized by their ability to lactate (express fluid from mammary glands) to nurse their young, and have hairy bodies. Curiously, the platypus (an egg laying mammal or monotreme) does not have teats. Although the female does express milk to nurse her young, that occurs through pores in her skin. The platypus possesses two genes that were previously found only in birds, amphibians, and fish. Mammals are one of four major divisions of quadrupeds, or four limbed creatures. The other groups are amphibians, reptiles, and dinosaur/birds.

How did Charles Darwin come up with his theories?

Charles Darwin had gone on his first voyage that took him to the Galapagos Islands. On that only isolated island he found 12 different kinds of finches- all with different beaks. Their habitats also differed according to their different beaks. Throughthese observations he came up with his theories.

How did Darwin come up the theory of evolution?

Darwin did not define evolution as such. What he became famous for after his voyage on the Beagle in the 1830s was defining the pressures that contribute to the ongoing survival of a species within its environment. This later became coined as 'natural selection' and is still regarded today as one of the most important contributions to biology.

Charles Darwin and his theory of evolution?

Charles Darwin was born in 1809. He sailed around the coast of South America on a ship called the Beagle for five years, he began his journey at the age of 25. While sailing he collected many different types of plants and animals on the mainland and on islands. He discovered that animals are all unique to their own island and the animals would come up to the humans because they had never met humans before. One of his most famous theories is his idea of the survival of the fittest, also called natural selection. It basically means: The unequal ability of individuals to survive and reproduce. Darwin proposed that organisms descended from common ancestors and that natural selection is the driving force for evolution. It took Darwin 25 years to publish his book about evolution. He thought that his theory took away a need for a God. Darwin's theory of evolution challenged both the Religious and the science community ideas at that time. Alfred Russel Wallace was the man who motivated Darwin to publish his book (The Origin of Species by Means of Natural Selection) because Wallace had come up with the same theory Darwin had and Darwin wanted to get credit for his work so he published his book before Wallace could.

How old was Charles Darwin when he came up with the theory of evolution?

Darwin started collecting information during his mid 20s. He contaminated most of his specimen collection because of lack of knowledge. Many of the specimens had long hence decomposed after the 5 year voyage on the beagle. He published the Origins of species at the age of 50. At the time it was published he stated the work was very flawed. He admitted he did not have a way to completely back up his claims. The book is commonly referred to as Darwin's theory of evolution. Darwin's research is the same as carbon dating, flawed and usually wrong.

How did Charles Darwin solve the theory of evolution?

Evolution was seen by many. But the mechanics were not well understood. One of Darwin's observations involved finches in the different Galapagos Islands. Each island had finches with slightly different physical attributes. Charles Darwin noticed that the shape of their beaks were different, depending on their primary food. Some beaks were shaped to make eating seeds more efficient. Others were shaped to eat insects. The finches that Darwin brought back as stuffed specimens, are still present in the British Museum. The collection is mounted, and it is easy to see the differences. Darwin felt that all of these different finches were descendants of finches that were blown on to the islands during a storm. Darwin was able to show that small differences gave finches on various islands an advantage. After many generations, each island had finches whose differences were very obvious. According to Darwin, the finch that lived on a specific island, did not choose to change. But small changes in beak structure, gave those birds an advantage. They were able to gather more food, and eventually had more living offspring. A good example are dandelions growing on a lawn. The lawn mower is set at a specific height. As you mow your lawn, the taller dandelions have their tops cut off. No flowers, they can't reproduce. But the few shorter dandelions are left, their pollen reproduce, and now most of the dandelions are short, close to the ground, and difficult for the lawn mower to cut them off.

What were the discoveries in the theory of evolution by Charles Darwin?

Darwin's Origin of the Species was quite controversial when it was first released because many people did not believe in evolution. Darwin's theory was that of natural selection, which meant that organisms possessed a varied ability to survive and procreate. Those having characteristics which enabled them to overcome obstacles or predators-- or other issues--and survive and procreate were named for obvious reasons the "survival of the fittest." That simply meant that those organisms having the strongest survival idiosyncrasies would win out over those not possessing such survival DNA and would live and procreate and become even stronger, in other words, survival of the fittest is a simple example of evolution through strength. There was so much controversy about this theory there was even a movie released about it called "Inherit the Wind" starring Spencer Tracy as famous attorney Clarence Darrow. In both real life and the movie Darrow defended a Tennessee school teacher for teaching Darwin's theory. The outcome was that the teacher and Darrow lost the trial, but the teacher was fined only $1.00.

When did Charles Darwin write the theory of evolution?

Darwin worked on his book most of 1859 and it was published 24 November, 1859. The Theory Of Evolution By Means Of Natural Selection, Or The Preservation Of Favored Races In The Struggle For Life. Of course Charles Darwin had been working on this theory more than twenty years before his book was published. He and Wallace both had papers submitted and read in 1858.
