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 Described evolution by natural selection?

Charles Darwin is credited with this theory in his book, The Origin Of Species. ---> Actually... Jean-Baptiste Pierre Antoine de Monet, Chevalier de la Marck (AKA Lamarck) was the first to propose the hypothesis that species change over time.


The change in the inherited characteristics of species over long periods of time is called?

The change of inherited characteristics of species over long periods of time is called evolution.


Compare and contrast Lamarck’s and Darwin’s theories of evolution: What are the similarities What are the differences?

Lamrack:Individuals change due to mutation (born with changes)Nature favors those best suited to survive and reproduceDarwin's:Change happens slowly over many generations.Common:Any individual can change responding to environmentAcquired traits can be passed on to offspring


Was Charles Darwin the first person to develop a theory of evolution?

Charles Darwin went to an island (Galapagos)where he studied the beaks of finches. He noticed that the although the birds were from the same species, they looked different. This is how he worked out that "Species change over time to adapt to their environment."


What did jean baptiste lamarck contribute to science?

Lamarck proposed an hypothesis that had species evolving desired traits and passing them to their offspring. For example, if you were a bodybuilder, your offspring would be born with larger than normal muscles. This hypothesis, while incorrect, was still significant in the history of evolutionary thought.

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.


How did lamrack propose that species change over time?

Lamarck proposed for inheritance of acquired traits. Example, giraffes stretched their neck to feed on shoots on tall trees. This lead to elongation of the necks, and they pass this traits to their offspring. This goes on and on, and eventually giraffes end up with long necks.


How did Darwin and Lamarck differ in their thinkinh 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 individuals with advantageous traits are more likely to survive and reproduce, leading to gradual changes in species over generations. Thus, while Lamarck emphasized individual effort and adaptation, Darwin focused on environmental pressures and genetic variation.


Explain lamarck principle of use and disuse?

Lamarck proposed that by selective use and disuse of organs, organisms acquired or lost certain traits during their lifetime. These traits could then be passed on to their offspring. Over time, this led to a change in species


How did Lamarck propse that species change over time?

he thought that an animal gained traits over its life, for example by stretching its neck it gained a longer neck. it was then able to pass on these traits to its offspring. he was wrong.


How did Lamarck pave the way for the work of later biologist?

he sugested that organisms could change during their lifetimesby selectively using or not using various parts of ther bodies. he also suggested that individuals could pass the acquired traits on to their offspring enabling species to change over time...that is how Lamarck paved the way for future biologists


What are similarities between Darwin's theory and Lamarck's theory of evolution?

They both propose that organisms are not immutable, but changes over time. However the mechanisms of the two theories are very different.


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.


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.


In what ways did Lamarck and Darwin agree?

Lamarck and Darwin both agreed on the idea that organisms change over time and that these changes can lead to the evolution of new species. They recognized the influence of the environment on the traits of organisms, suggesting that adaptations can arise in response to environmental pressures. Additionally, both scientists acknowledged the importance of variation within species, although they differed significantly in their explanations of how these changes occur.


What are the same between Darwin and lamarck?

That they were both transformationists, a word the meant in those days one thought organisms evolved over time, and thought species arose by natural processes. The mechanisms proposed by them varied a great deal though.


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.
