What are the specific clues that most clearly distinguish a Darwinian explanation from a Lamarck explanation?
Darwinian evolution is based on the idea of natural selection, where individuals with advantageous traits are more likely to survive and reproduce, leading to the gradual accumulation of these traits in a population over generations. In contrast, Lamarckian evolution suggests that acquired traits during an individual's lifetime can be passed on to offspring. Specific clues that distinguish these explanations include the basis for inheritance of traits (genetic in Darwinian vs. acquired in Lamarckian) and the mechanism of how populations change over time (gradual accumulation of genetic changes in Darwinian vs. direct transfer of acquired traits in Lamarckian).

What are the specific clues that most clearly distinguish a darwinian explanation from a lamarckian explanation?
A key distinction between Darwinian and Lamarckian explanations is the inheritance of acquired traits: Lamarck proposed that organisms could pass on traits acquired during their lifetime to their offspring, while Darwin's theory of natural selection relies on genetic variation and heritability of selected traits over generations. Additionally, Darwinian evolution emphasizes gradual changes through natural selection acting on variation within populations, whereas Lamarckian evolution suggests that organisms can adapt quickly and purposefully to their environment.
What scientist had ideas about evolution and adaptation that influenced Darwin?
Jean-Baptiste Lamarck, a French biologist, proposed the idea of inheritance of acquired characteristics and the concept of transformational evolution. These ideas influenced Darwin's thinking on evolution and adaptation. However, Darwin's theory of natural selection ultimately diverged from Lamarck's ideas.
Stated that inheritance of acquired traits caused change in a species over time?
This statement is incorrect. Inheritance of acquired traits, as proposed by Jean-Baptiste Lamarck, is not a valid mechanism for evolution. Evolution occurs through natural selection acting on genetic variations already present in a population, not through the direct inheritance of acquired characteristics.
What was lamarck's incorrect hypothesis regarding inheritance?
Lamarck's incorrect hypothesis regarding inheritance.... Lamarck did not know how traits were inherited (Traits are passed through genes) Genes are not changed by activities in life. They change through mutation occurs before an organism is born.
What were the two ideas proposed by Lamarck to explain the mechanism of evolution?
Jean-Baptiste Lamarck proposed two ideas to explain the mechanism of evolution: the inheritance of acquired traits and the use and disuse of organs. According to Lamarck, organisms could pass on traits they acquired during their lifetime to their offspring, and that the use or disuse of certain organs could lead to changes in those organs over time.

What did Lamarck propose a scientific explanation for and why?
Lamarck proposed a scientific explanation for evolution because organisms evovled through the inherititance of acquired charactaristics.
What did lamarck propose a scientific explanation for?
Lamarck hypothesized that organisms evolved through the inhertitance of acquired charactaristics.
Was Lamarck's explanation scientific?
No. In fact he faked his data.
What are the Lamarck's 3 theories?
Do Lamarck's theories provide a good explanation for the change in months? Why or why not?
Who was the first to offer a scientific explanation for how species changed?
Jean- Baptiste Lamarck
What is the role environment in Lamarck's explanation?
In Lamarck's explanation of evolution, the environment plays a role in shaping the traits of organisms through the principle of use and disuse. Lamarck proposed that organisms could acquire or lose certain traits based on their interactions with the environment during their lifetime, and these acquired traits could be passed on to their offspring. This theory is known as the inheritance of acquired characteristics.
Was lamarck's explanation scientific .why or why not?
It was his theory. When data was finally collected (near his death), it was found that his theory was (sort of) wrong.
Which idea did Lamarck propose that was rejected by fellow scientist?
That organisms pass on traits acquired in their lifetimes. It was rejected in favour of Darwinian evolution, in which species and not individuals evolve, but Larmarckism is valid to a point where epigenetics is concerned.
Why was Lamarck's theory of evolution incorrect?
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.
Which idea did lamarck propose that was rejected by his fellow scientists?
That organisms pass on traits acquired in their lifetimes. It was rejected in favour of Darwinian evolution, in which species and not individuals evolve, but Larmarckism is valid to a point where epigenetics is concerned.
Which describes Lamarck's explanation for changes in the fossil record?
Lamarck's explanation of evolution is based on two principles: use and disuse and the inheritance of acquired characteristics. Lamarck's "use and disuse" principle explained his belief that the body parts that are commonly used become larger and stronger such as a giraffe's neck, while those that are not used deteriorate and become smaller. He also believed that an organism could pass these modifications to its offspring through the inheritance of acquired characteristics. Thus, Lamarck thought that evolution is driven by the innate drive of organisms to become more complex. Although he was later proven wrong, he was insightful in observing and recognizing that gradual evolutionary change does exist.
