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.
How did lamark propose that species change over time?
Jean-Baptiste Lamarck suggested an idea that Darwin would later expand upon. Lamarck suggested that any changes a creature underwent during its lifetime would be passed down to the offspring. He also believed unused parts would just go away over time, due to this.
How did jean-babtiste lamark suggest as to how species change over time?
Jean-Baptiste Lamarck proposed that species change over time through the mechanisms of use and disuse and the inheritance of acquired characteristics. He believed that traits that were used frequently would become stronger and more developed, while those that were not used would diminish. These acquired traits could then be passed on to the next generation, leading to gradual changes in a species. Although Lamarck's ideas were eventually overshadowed by Darwin's theory of natural selection, his thoughts on evolution were foundational in the study of biology.
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.
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.
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's theory believed a butterfly could change its color?
Jean Babtist Lamark
Who introduce the 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.
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.
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.
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.
When was LaMark Carter born?
LaMark Carter was born in 1970.
How did other scientists work help Darwin develop his theory of natural selection?
Other scientists like Lamark Baptist Wallace helped by going out and exploring with him and publishing his articles.
