What was Charles Darwin's Education?
While he was studying finches (small birds) in different islands, he noticed that although they were from the same species, they were different. He realised that over time species change and adapt to their environment. This is how he came up with the Theory of Evolution.
What is important of the theory of evolution to modern biology?
All organisms alive today have been, is and will be evolving. Therefore nothing in biology makes sense except in light of evolution. For example, in medicine, the resistance of bacteria to antibiotics would not make sense except for evolution. If a drug has been killing bacteria so effectively (e.g. penicillin) for decades, why would it start to gradually become less and less effective? The answer lies in the fact that the drug creates an enormous selection pressure in favour of resistance, and this leads to an increase in the proportion of resistant bacteria in each generation. This process is an artificial and miniature version of evolution but it is evolution nonetheless. In nature, the selection pressure is usually much smaller and the process takes much longer (millions of years instead of decades).
How many people believe in the theory of evolution?
When the evolutionary theory was first proposed, people didn't believe it. Often, religion and evolution contradict themselves and even today, there are many people who favor creationism over evolution.
Scientific study of the Earth, including its composition, structure, physical properties, and history. Geology is commonly divided into subdisciplines concerned with the chemical makeup of the Earth, including the study of minerals and rocks the structure of the Earth and volcanic phenomena landforms and the processes that produce them and the evolution of planetary bodies and their satellites (astrogeology); and its various branches, such as mining geology and petroleum geology.
When it came to Darwin explaining the origins of variations within species?
Various evolutionary theories had already started to form when it came time for Darwin to publish On the Origin of Species. The book attracted interest on a national level and made arguments for "survival of the fittest."
What did darwin call the process by which evolution takes place?
The book, On The Origin Of Species, " suggested " that organisms evolve through the process of natural selection. The nonrandom survival and reproductive success of randomly varying organisms
What was the name of Darwins famous book published in 1859?
the work on Darwins most famous work was called? is british animals
What did Charles Darwin never know?
WikiAnswers is not a quiz site. We are a question and answer website.
He basically covered the tips of the sprouting seeds which would cease the growth of the sprouting seed as the receptors did not receive light, whereas the sprouting seeds uncovered continued to curve and grow towards the light. I'm not sure if he discovered it cause from what i've read it didn't result in any scientific reasoning. I hope that kinda helped answer your question:)
What did Charles Darwin write?
The most famous is On The Origin of Species.
He also wrote The Voyage of the Beagle, The Descent of Man, The Expression of the Emotions in Man and Animals, and a book about worms.
This is NOT a complete list, necessarily. These were the most common books.
Lamarck was correct about the connection between the environment and evolution. He saw that the organism changes based on the environment and its survival. However, Lamarck is not well-known for his advances in the field. Instead, he is known for the incorrect mechanisms for evolution that he proposed, including "use and disuse" and "inheritance of acquired characteristics." (A small note, Lamarck definitely did not have a "theory," he had hypotheses).
Why was Darwin's Theory only gradually accepted?
people of Darwin's time couldn't accept his theory because they didnt believe in adaptation which has to do with evolution. Also because Darwin couldn't explain it in detail and how it works therefore his argument was weak
What term van be used to describe evolution by natural selection?
the theory about how organisms change over time.
Why would many people not accept the heliocentric theory?
It means literally, "Sun centred", and it is true for our Solar System and others like it: a set of planets orbiting a star. So it IS accepted on that scale!
It is not true for the Universe as a whole, but a galaxy has some central mass holding it together, and the candidate for that is huge 'black hole'.
Where did Charles Darwin collect most of his evidence?
Darwin traveled on HMS Beagle. This voyage was extensive, stopping at many exotic places and a trip which took nearly five years; they did not to return to England until October 2, 1836. During that time, they visited Tenerife, the Cape Verde Islands, the Brazilian coast, Argentina, Uruguay, Tierra del Fuego, Chile, the Galapagos Archipelago, Tahiti, New Zealand, Tasmania and the Keeling Islands

What were four lines of evidence Darwin used to support his argument for evolution?
The classification of lines of evidence into four different types is quite arbitrary. One could as easily distinguish two types, or five, or ten, depending on the criteria used.
For instance: one might distinguish between evidence stemming from research in extant lifeforms on one hand, and from extinct lifeforms on the other. One might distinguish between genetic data and morphological data.
For information on various lines of evidence supporting evolutionary theory, see links below.
1. We have seen species change, and have even caused species to change by our own practices of animal breeding. In recent times we have seen the appearance of such things as antibiotic resistant bacteria and insecticide resistant insects; clearly, they have evolved. They were not always here.
2. In the development of the human embryo (or the embryo of another species) we see that the organism, as it grows from a single celled zygote to a fully developed fetus, goes through what appear to be evolutionary stages. At one point the embryo resembles a fish, having a tail and gills. This is a clear indication that earlier forms from which we evolved are still a part of human genetics.
3. Many species, including humans, have vestigial organs. We have the vermiform appendix, an organ which serves no purpose. More dramatically, whales have very tiny leg bones embedded within their bodies even though they never grow legs. We can find all sorts of residual features left over from earlier stages of evolution.
4. We can trace all sorts of connections, both physiological and biochemical, among different species. The various families and groups which species form, and the similarities within those groups, speak of shared descent and the process of evolution.
What did Darwin conclude after his trip?
Species are modified to their specific environments, and that is why they are not identical all over the world.
What are five conditions that can disrupt genetic equilibrium and cause evolution to occur?
Three ways genetic equilibrium can be disrupted include, mating not being random, mutations occur, and natural selection occurs. Two other disruptions are organisms move in and out of the populations and many populations are too small to begin with.
