Lamarck's theory of evolution, known as Lamarckism, proposed that organisms could pass on traits acquired during their lifetime to their offspring, such as a giraffe stretching its neck to reach higher leaves and then having offspring with longer necks. This idea was incorrect because it lacks genetic basis; traits are inherited through genes, not acquired characteristics. Modern genetics and Darwinian natural selection provide a more robust explanation for evolution, emphasizing heritable variations that arise through mutations rather than acquired traits.

What was Lamarcks theory?
Lamarck's Hypothesis of Evolution(Small note before answer: Lamarck had a hypothesis, not a theory) Lamarck, as well as other naturalists, hypothesized evolution via environmental change before Darwin. However, many failed to account for changes in the fossil record and interactions of the phenotypes of animals on their environment. Despite Lamarck's advances in the field, he is most remembered in history for the incorrect mechanisms of this evolution that he posited.Lamarck's hypothesis of evolution appeared in his Zoological Philosophical Work written in 1809, featuring two mechanisms of evolutionary change: use and disuse and inheritance of acquired characteristics.His evolutionary hypothesis was as follows:Environmental changes generate new needsThese needs determine the use or disuse of some organsSuch organs develop or are diminishedThe acquired characters are hereditary
Which of lamarcks ideas was later found to be incorrect?
The idea of acquired characteristics. For instance. The idea that a blacksmith, who would develop enormous muscles due to his trade, could pass these physical attributes on to his children.
Why were the Galapagos islands so important to Darwin's theory?
It was where he developed his theory. The Galapagos are considered the "Laboratory of Evolution." Evolution is easily observable here.
How does Alfred Russell Wallace's theory compare to Darwin's theory of evolution?
its the same
What theory does the fossil record support?
It is generally thought to support the Theory of Evolution.
How is lamarcks theory of evolution different from theory of evolution?
Make me cum daddy~! Make me moan~!
Lemarck's ideas of evolution are known as the inheritance of acquired characteristics what was incorrect about his theory of how organisms evolve?

Is evolution called a theory?
Evolution is called a theory based on known researched information. When or if some of the information is found to be incorrect or if new information becomes availabe, the theory may be revised.
How does the cell theory show that Darwin's theory of evolution was incorrect?
It does not. Cell theory is fully compatible with evolutionary theory. Does this mean we know everything about the evolution of cells? No. We say we do not know, not that cell theory shows that evolutionary theory is incorrect. ( except, of course, if you are referring to heritability. This Darwin got wrong, but this is not directly related to cell theory )
How was Darwin's theory of evolution different from lamarcks?
In Darwin's theory, natural selection plays the key role. Organisms vary through random mutations--slight changes from their parents. The environment determines which are most likely to survive. In Lamarck's theory, changes in phenotype are inherited. This is now known to be (largely) incorrect.
What is the difference between the theory of language and evolution?
Theory of evolution refers to animals and plants evolution along the time. Language evolution is another issue, not entirely related to the theory of evolution. It follows the theory of evolution on some way but it is related to culture evolution, not to the physical attributes evolution.

What are the differences between Darwin's and lamarcks theory of evolution?
Larmark's theory was based on the idea that organisms inherited characteristics that they had acquired in life - so, if you have a scar your offspring will have scars. Darwin's theory assumed that offspring inherited characteristics from their parents, but they were more likely to survive to breed if there was advantage to those characteristics.
Is evolution a theory or hypothesis?
Evolution is an observed and observable fact. The theory of evolution by natural selection explains many things about evolution. The theory generates testable hypothesis, as any good theory does. Remember, theory is the highest concept in science.
Complete history of a theory of evolution?
There are many books that describe the theory of evolution. For example, there is a book called Evolution: The Remarkable History of a Scientific Theory.
What is the movement that held to the theory of evolution?
The scientific movement accepts the Theory of Evolution. The Theory is the basis for the science of biology.
What is an example of the evolutionary theory of government?
Tribal communities are good examples of evolutionary theory of government, because the family unit is often important but overseen by a leader. A biblical example is the 12 tribes of Jacob because the head of the family formed the larger government. Each tribe was headed by one of Jacobs son, and Jacob ruled over them all.
