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.
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.
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.
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.
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.
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
Who believed that species evolve by keeping traits that their parents developed during their lives?
Jean-Baptiste Lamarck
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.
What did lamarck propose a scientific explanation for?
Lamarck hypothesized that organisms evolved through the inhertitance of acquired charactaristics.

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 the name of the first scientist believed in the theory of evolution?
Charles Darwin is often credited as the first scientist to propose the theory of evolution through natural selection in his book "On the Origin of Species" published in 1859.
