What was Charles Darwin 4 main observations about evolution?

Answer 1

Don't know if this is exactly the four you're looking for, but his theory can be summarised as:

1. Organisms vary.
2. Some of this variation is heritable.
3. More children are born than can survive.
4. Those children that vary in ways that make them better suited to the environment will stand a better chance of surviving to reproduce.

Answer 2

Darwin's "evolutionary and comprehensive vision" is a monistic one, it shows that our universe is a "unitary and continuous process," there does not exist a "dualistic split," and that all phenomena are natural. Darwin's idea, it is written,
"is the most powerful and the most comprehensive idea that has ever arisen on earth. It helps us understand our origins ... We are part of a total process, made of the same matter and operating by the same energy as the rest of the cosmos, maintaining and reproducing by the same type of mechanism as the rest of life ..."8 (Sir Julian Huxley.)
The theory of evolution is no longer just a theory; an overwhelming amount evidence has accumulated since Darwin. Darwin's theory has never been successfully refuted. Darwin discovered a law just as surely as Copernicus, Galileo and Newton discovered laws: natural laws. Just as the earth is in orbit and has come to be and is depended on the force of gravity, a natural law; so life has come into being and exists and is depended on the force of natural selection. One need not necessarily understand the why or the how of it, but a natural law such as gravitation or selection nonetheless exists, whether a particular puny human being, or group of them believe it or not.
The theory as presented in Darwin's The Origin of Species, I should say, was not new to the world and it cannot be attributed to Darwin. The theory, contrary to popular belief has been around since Aristotle and Lucretius. Darwin's contribution is that he gathered indisputable evidence, and he set forth a theory on how evolution works, the theory of natural selection. Darwin: "It may be said that natural selection is daily and hourly scrutinising, throughout the world, every variation, even the slightest; rejecting that which is bad, preserving and adding up all that is good; silently and insensibly working, whenever and wherever opportunity offers, at the improvement of each organic being in relation to its organic and inorganic conditions of life. We see nothing of these slow changes in progress, until the hand of time has marked the long lapses of ages, and then so imperfect is our view into long past geological ages, that we only see that the forms of life are now different from what they formerly were."9

We will let Julian Huxley sum up Darwin's place in the history of science:
"Darwin's work ... put the world of life into the domain of natural law. It was no longer necessary or possible to imagine that every kind of animal or plant had been specially created, nor that the beautiful and ingenious devices by which they get their food or escape their enemies have been thought out by some supernatural power, or that there is any conscious purpose behind the evolutionary process. If the idea of natural selection holds good, then animals and plants and man himself have become what they are by natural causes, as blind and automatic as those which go to mould the shape of a mountain, or make the earth and the other planets move in ellipses round the sun. The blind struggle for existence, the blind process of heredity, automatically result in the selection of the best adapted types, and a steady evolution of the stock in the direction of progress...
Darwin's work has enabled us to see the position of man and of our present civilization in a truer light. Man is not a finished product incapable of further progress. He has a long history behind him, and it is a history not of a fall, but of an ascent. And he has the possibility of further progressive evolution before him. Further, in the light of evolution we learn to be more patient. The few thousand years of recorded history are nothing compared to the million years during which man has been on earth, and the thousand million years of life's progress.

Answer 3

1. Only a group can eveolve, not an individual.
2. Survival of the fittest (Natural Selection) nature 'chooses' the organisms that will survive based on what characteristics they have that enable them to adapt to the environment.
3. Something about the environment impacts how a group adapts to the environment.
4.There are these five stages that a group has to go through to have 'evolved'
I'll try and remember them:
Overpopulation
Competition
Variation (a change in the environment)
Natural selection
Speciation

I think those are them.

Answer 4

1. Over production.(The organisms multiply in geometric ratio)
2. Struggle for existance.(The number of survivors remains constant).
3Natural selection/survival of fittest( variations under nature).
4. Origin of species,by continued changes and adaptations.

Answer 5

Darwin is a fictional character created by the Coca Cola companies to sell stuffed monkeys to British Tourists in South America.

God Created me in one day! Yes it was a rush job but at least I don't look French!!!

BTW I like licking freezers in supermarkets.
