What else can I help you with?
What question did both Lamarck and Darwin try to answer with their theories of evolution?
What is the mechanism that causes evolution. Both knew evolution occurred and occurs but did not know how or why. Lamark's " desire to evolve " and " acquired characteristics " failed to explain evolution. Darwin's theory of evolution by natural selection was the better explanation.
What important controbutions did Charles Darwin make?
Charles Darwin is best known for his theory of evolution by natural selection, which revolutionized our understanding of how species change over time. His work laid the foundation for modern biology and provided a unifying principle to explain the diversity of life on Earth. Darwin's contributions continue to influence scientific research and our understanding of the natural world.
Who believed if an individual uses a trait more it gets bigger lamark or Darwin?
Jean-Baptiste Lamarck believed that if an individual uses a trait more frequently, it will become more developed and prominent in subsequent generations. Charles Darwin, on the other hand, proposed that favorable traits are naturally selected for in a population over time through the process of natural selection.
Why did scientists reject Lamark's idea of evolution?
Lamarck led the way for and had ideas that helped Darwin. However, his observations regarding the mechanisms of evolution were, with the exception of one, totally backwards. To summarize Lamarck, he hypothesized that organisms somehow had a choice in their traits and could change to fit the environment (he called these ideas his theories of need and his theory of use and disuse). The part he was correct on was that should an organism change, they would pass the traits on to their offspring. Darwin said, basically, the opposite. Darwin observed that organisms were born with slight differences (variations) and those variations might give some members of a species an advantage in the struggle to survive in the environment. The reward for survival was that the organism got to reproduce and pass those traits on to their offspring. Of course, the offspring might show some variation and the whole process would continue to repeat. However, the bottom line with Darwin (and contrary to Lamarck) was that an organism had no choice in its traits as an organism is born with or without the advantage. Darwin, without knowing its mechanisms, recognized that genetics played a part in evolution. Darwin died not knowing of Mendel's work on genetics which, of course, substantiates Darwin's theory.
What were lamark's theories?
Jean-Baptiste Lamarck proposed the theory of inheritance of acquired characteristics, which suggests that traits acquired during an organism's lifetime can be passed on to its offspring. He also proposed the idea of use and disuse, where organs that are used frequently become more developed while those that are not used deteriorate over time. However, Lamarck's theories have largely been discredited in favor of Darwin's theory of natural selection.

Which theory is correct or wrong between lamark and Darwin?
Theories are just that. Theories are unproven ideas by people to explain a certain phenomena.
Who introduced the evolution theory?
Darwin introduced the modern theory of evolution by natural selection, but it was also introduced by Lamark and other earlier biologists but Darwin was first to theorize about natural selection as the mechanism.
Why is Lamark not called the father of Evolution?
Because it was Darwin who made it a scientifically plausible explanation, by providing a mechanism by which evolution could occur....Natural Selection.
Why is Charles Darwin and why is he so important?
He is considered by many to be the father of the Theory of Evolution, though his uncle and Lamark had the genesis of that idea.
Who introduce the theory?

Whose theory of evolution conflict with Darwin's theory of evolution?
French naturalist Jean-Baptiste Lamarck's theory of evolution conflicted with Darwin's theory. Lamarck proposed that acquired characteristics could be passed down to offspring, while Darwin's theory emphasized natural selection and gradual change over generations.
How did Lamarck get into the Darwin's theory?
He didn't. Lamark's theory of acquired characteristics preceded Darwin's theory by some years. Almost 50 years.
What was the difference of Lanmark and Darwin's theory of evolution?
Darwin believed that organisms evolved due to natural selection. Whereas Lanmark suggested that the characteristics acquired during an organisms life i.e. academic ability, could be passed to the next generation.
What is the difference between the lamarack and Charles Darwin theory of evolution?
The mechanisms for evolution. Lamark had a concept called acquired characteristics, an organism " needed " to evolve and any development of the organism, say developed muscles, could be passed on to progeny. Darwin's theory showed all organisms as variants and those with the best adaptions to their environment were reproductively successful and passed these traits on to progeny and over time the population evolved.
