Charles Darwin

Around 1793.

The shapes of their beaks were different from mainland finches and they worked better to get the food they needed.

An example often given is the peppered moth. It has two forms, a light speckled one and a dark plain one. They often sit on tree trunks. Before the industrial revolution the speckled ones were well camouflaged against the lichen covered bark, and the dark ones were very conspicuous and got eaten by birds. Consequently there were far more speckled ones. When city air became full of smoke and soot the lichen died and the trunks became black. Now it was the speckled form that stood out and the numbers of black ones in cities went up. The trend has reversed again as we have burned less coal and cleaned up the environment.

It's important to remember that this is natural selection, but not yet evolution. Both forms of the moth are still being born. However it's possible to see that if the two different environments persisted for a long time then two distinct forms might come about which no longer interbred.

That the offspring of one species may adapt to it's surroundings and live longer then though without the modification.

The observations he made on the island led Darwin to believe that organisms slowly adapt to their environment. This led him to form the survival of the fittest theory.

Darwin did not really mean survival of the fittest, he meant survival of the most adapt. For example, a faster and stronger gazelle could out run the cheetah, but still be caught, but a smarter and more intelligent gazelle could out wit the cheetah and survive. So it is in the end, survival of the most adapt.

If an animal is not well adapted or fit for its environment, it may struggle to find food, evade predators, or reproduce effectively. This can lead to increased mortality rates and reduced population sizes over time. Ultimately, those individuals may not survive long enough to pass on their genes, leading to a gradual decline in the species' overall fitness within that habitat. In extreme cases, poor adaptation can result in extinction.

Charles Darwin served as a naturalist on the HMS Beagle for almost five years, from 1831 to 1836. During this journey, he collected extensive observations and specimens that contributed to his later work on evolution and natural selection. His experiences aboard the Beagle were crucial in shaping his scientific ideas.

Charles Darwin was particularly interested in a variety of organisms, notably finches, tortoises, and mockingbirds from the Galápagos Islands, which played a crucial role in shaping his theory of evolution by natural selection. He also studied other species, including barnacles and orchids, to understand variation and adaptation. His observations of these organisms helped him formulate his groundbreaking ideas about the processes of evolution and the diversity of life on Earth.

Adaptation is when a species is able to change over time to new changes in their environment.

The book made Darwin think that sense the earth is so old, there would be plenty of time for organisms to change slowly.

Yes, he was Charles Darwin.

Charles Darwin's voyage on the HMS Beagle lasted nearly five years, from December 27, 1831, to October 2, 1836. The expedition took him to various locations, including South America, the Galápagos Islands, and Australia, where he collected a wealth of data and specimens. This journey significantly influenced his later work on the theory of evolution.

Darwin was puzzled about the many adaptations of the finches on the Galapagos Islands

Darwin Watterson, a character from the animated series "The Amazing World of Gumball," typically wears a simple, orange, fish-like body with a broad smile and big eyes. He has little fins for arms and legs, and he often sports a pair of white sneakers. His appearance is cheerful and vibrant, reflecting his friendly and optimistic personality.

Finches and turtles

On the Origin of Species by Means of Natural Selection is probably his most famous book

Lyell's theory of uniformitarianism emphasized that geological processes observed today have operated uniformly and continuously over time, shaping Earth's surface. This idea challenged prevailing beliefs of cataclysmic events shaping the Earth's history. By advocating for gradual, natural processes, Lyell's theory laid the foundation for modern geology and the principle of uniformity in Earth sciences.

It is thought that the finches have a common ancestor. Separated on different islands, each island eventually produced different finches.

That is Darwin's principal of Natural Selection, sometimes called survival of the fittest.

Because it went against religious dogma and put man on the same level as animals.
