Lamarck's theory is that an organism can pass traits to their offspring that they have acquired in their lifetime. One example commonly used is that he felt giraffes acquired long necks because of generations of them stretching and trying to reach higher leaves on the tree. He thought that these stretched muscles would be passed down to their offspring. This has been proven wrong because this is not how evolution takes place. If you would cut off the tails of two mice and then breed them their offspring would not have short tails.

Who theorized that organisms evolve by passing on advantageous traits to their offspring?

Lamarck did. Neodarwinism theorises that species evolve when gene frequencies change, not individual organisms. Larmarkism is true for epigenetic inheritance, favourable and unfavourable characteristics alike.


What did lamarck propose the species evolve?

Jean-Baptiste Lamarck proposed that species evolve through the inheritance of acquired characteristics, a concept known as Lamarckism. He suggested that organisms adapt to their environments during their lifetimes and that these adaptations could be passed on to their offspring. For example, he believed that a giraffe's neck became longer because ancestral giraffes stretched to reach higher leaves, and this trait was then inherited by future generations. Although Lamarck's ideas were later overshadowed by Darwin's theory of natural selection, they played a significant role in the early development of evolutionary thought.


How did lamarck's theory affect Darwin's thinking?

Lamarck's theory of inheritance of acquired characteristics influenced Darwin by introducing the idea that organisms could change over time in response to their environment. Although Darwin ultimately rejected Lamarck's mechanisms, he was inspired by the concept of adaptation and the idea that species are not fixed. This led him to explore natural selection as a more robust explanation for how species evolve and adapt. Thus, while Darwin diverged from Lamarckism, he acknowledged its role in shaping his thoughts on evolution.


What differences in theory Lamarck and Darwin?

Lamarck and Darwin had differing theories on how species evolve. Lamarck proposed that organisms evolve through the inheritance of acquired characteristics, suggesting that traits gained during an organism's lifetime can be passed to offspring (e.g., giraffes stretching their necks). In contrast, Darwin introduced the theory of natural selection, which posits that individuals with advantageous traits are more likely to survive and reproduce, passing those traits to future generations. While Lamarck emphasized adaptive changes within a lifetime, Darwin's theory focused on gradual changes over generations driven by environmental pressures.


Where did Lamarck and Darwin agree on the evolution theory?

Lamarck and Darwin both agreed that species evolve over time and that this process leads to the adaptation of organisms to their environments. They recognized the importance of environmental factors in shaping traits and behaviors. However, while Lamarck proposed the inheritance of acquired characteristics as the mechanism for evolution, Darwin introduced natural selection as the primary driving force, marking a fundamental difference in their theories.

What was wrong about lamarck's theory of how species evolve?

Lamarck's theory is based on acquired characteristics. In other words if you break your arm your future children will be born with broken arms.

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.

Who was Lamarck and what was his theory?

Jean-Baptiste Lamarck was a French naturalist known for his early theories of evolution, particularly his concept of inheritance of acquired characteristics. He proposed that organisms could pass on traits acquired during their lifetime to their offspring, suggesting that species evolve over time in response to their environments. While his ideas laid groundwork for future evolutionary thought, they were later largely supplanted by Darwin's theory of natural selection. Lamarck's contributions remain significant in the history of biology, highlighting the evolving understanding of how species change.


Who was the first to offer a scientific explanation for how species changed?

Jean- Baptiste Lamarck


How did Lamarck propose that species change over time?

Lamarck proposed that by selective use or disuse of organs, organisms acquired or lost certain traits during their lifetime. Then passed onto offspring-leading to change in species


What is an acquired characteristic what role did Lamarck's think acquired characteristics played in evolution?

An acquired characteristic is a trait that an organism develops during its lifetime as a result of environmental influences or experiences, rather than being inherited genetically. Jean-Baptiste Lamarck proposed that these acquired characteristics could be passed down to subsequent generations, suggesting that organisms evolve by adapting to their environments over time. This idea, known as Lamarckism, posited that use or disuse of traits could lead to their enhancement or reduction, thereby influencing the evolution of species. Although Lamarck's theory has been largely discredited in favor of Darwinian natural selection, it was an early attempt to explain how species change over time.
