Darwin's three major contributions to evolutionary thought are;
1. There is genetic variation in all species
2. The variability is inherited - passed from parents to offspring
3. There are more offspring born than that survive to reproductive age
I only have two, sorry :P
hope this helps!
It has been put to rigorous testing over 150 years and has stood that test. It best explains the data. It is supported by massive amounts of evidence from several disciplines. Actually, it is no longer just Darwin's theory but has been modified to some degree in that 150 years. For instance, Darwin was wrong about the hereditary mechanisms.
The mechanism that drives adaptive change in organisms that can lead to speciation.
In Darwin's own words.
The theory of evolution by means of natural selection.
Natural selection can change a species in small ways, causing a population to change color or size over the course of several generations. This is called "microevolution."
But natural selection is also capable of much more. Given enough time and enough accumulated changes, natural selection can create entirely new species, known as
"macroevolution." It can turn dinosaurs into birds, amphibious mammals into whales and the ancestors of apes into humans.
Darwin also described a form of natural selection that depends on an organism's success at attracting a mate, a process known as sexual selection.
Other naturalists believed that all species were believed to remain much the same throughout time.
Darwin, however, noticed similarities among species all over the globe, along with variations based on specific locations, leading him to believe that they had gradually evolved from common ancestors.
He came to believe that species survived through a process called "natural selection," where species that successfully adapted to meet the changing requirements of their natural habitat thrived, while those that failed to evolve and reproduce died off.
what are the main components in Charle Darwin theory
1. How organisms are suited for life in their environments
2. The many shared characteristics of life.
3. The rich diversity of life.
diversity and distribution of species
uniformitarianism
Malthusian Law
1) Fitness
2)Fitness results from adaptation
3) adaptations are the result of natural selection and in the long run the evolution of a species
Evidence of evolution
Fossil record
Examples and observations
Because due to Darwins theory of evolution, fossils lead to adaptations over time therefor giving us reason to find evolution within human beings and animals.
They adapt via evolution like all other animals do or have done , darwins theory of evolution still to this day is relative.
Abiogenesis, or more commonly known as the origin of life itself, is not part of Darwin's theory of evolution.
No theory contradicts evolution. Evolution is the basepoint of all Biology.
There is no " theory of evolution " as evolution is a fact. The theory is; the theory of evolution by natural selection and explains much about the fact of evolution. Charles Robert Darwin and Alfred Russel Wallace come up with the theory of evolution by natural selection, though natural selection is a phrase coined by Darwin.
Darwins theory of evolution :)
Darwins theory of evolution
no the theory of evolution is a species becoming more advanced not over populated
There is strong evolutionary evidence by people such as Darwin.There is evidence in our biological structures ie: bones and DNA in particular.Although evolution (the theory) is debated there is very strong evidence (look at Darwins books and research)
fittest
can someone help me please
Charles Darwin studied birds, medicine, and theory of evolution.
Did you mean Charles Darwin? (Darwinism, Theologists and Philosopher?)
There is no proven theory of evolution only the physical evidence of what Chuck Norris has allowed to live.
Genetic variations are produced by mutations and sexual recombination
If you're referring to the guy who formed the theory of evolution, no. He died in 1882, I believe.
