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.
Who was the first to offer a scientific explanation for how species changed?
Jean- Baptiste Lamarck
How did Lamarck think evolution worked?
Fossils or natural selection
What were lamark's theories?
Lamarck's theory is that he thought that the long necks from giraffes come from other species of mammals.
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.
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.
Stated that inheritance of acquired traits caused change in a species over time?
Lamarck thought acquired traits were past on, but he was prover wrong by Darwin and his natural selection idea.
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 can result in the immediate creation of a new species?
That depends on what you mean by 'immediate'. Drastic rates of evolution are possible in many species, where mutations are either relatively very common or where the environment results in harsh selection. But nothing will make one species "immediately" evolve into another in one generation, or even two or ten.
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?
How did Lamarck think evolution worked?
Fossils or natural selection
Does an individual a population or a species evolve?
Populations evolve.
