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.
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.
Who was the first to offer a scientific explanation for how species changed?
Jean- Baptiste Lamarck
How did Darwin and Lamarck differ in their thinking about change in species?
Darwin and Lamarck had fundamentally different views on how species change over time. Lamarck proposed that organisms could acquire traits during their lifetime and pass those traits to their offspring, a process known as inheritance of acquired characteristics. In contrast, Darwin introduced the theory of natural selection, suggesting that species evolve through the differential survival and reproduction of individuals based on heritable traits that confer advantages in a given environment. This marked a significant shift toward understanding evolution as a gradual process driven by natural mechanisms rather than intentional adaptations.
How did Lamarck think evolution worked?
Fossils or natural selection
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.
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.
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

What species of Pokemon does the oval stone work on?
I think you evolve Happiny into Chansey with the oval stone? They have to hold it and level up I think?
If the human species continues to evolve what kinds of changes do you think might occur?
One thing is that scientist think we will lose our pinkie toe
Which scientist believed that species gradually improved towards perfection due to fluida?
Jean-Baptiste Lamarck
Why was Lamarck's theory of evolution not eccepted?
Not well supported by the evidence and basically just assertion. Lamarck asserted that acquired characteristics, such as muscles developed during one's lifetime, were heritable. They are not. He also asserted that an organism had a " desire " to evolve. This was also not true.
