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.
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 is lamarck and what is his scientific evidence?
LAMARCK proposed the concepts of evolution called as Lamarckism.his theory consisted of two headings 1-use and dis use of organs 2-in heritance of acquired characters...
What are three areas of Lamarck's hypothesis of evolution?
Main points of Lamarck's theory are the following . 1 Changing environment produced need for new organs . 2 there is an increase in size of organs and organisms . 3 use and dis use of organisms . Inheritance of acquired characters .
Who proposed that acquired traits could be passed on to offspring?
This is a theory that states that some characteristics of an individual are acquired as opposed to inherited. For example, some frogs have mutations because of pollutants in their environment, whereas a person who has blue eyes probably has them because they inherited them from their parents.
Who proposed that organisms adapt to their environment?
Lamarck.
Lamarck proposed that organisms?
Lamarck proposed that organisms developed new features as a result of a 'inner urge' for improvement and that they passed on these improvements to their young/offspring. He did not accept that animals could become extinct.
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.
Is it true lamarck proposed that all organisms have an innate tendency toward complexity and perfection?
Yes, it is true
What were the main ideas Lamarck proposed that influenced Darwin?
Lamarck proposed that traits acquired during one's lifetime could be passed to the next generation.
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 the role environment in Lamarck's explanation?
In Lamarck's explanation of evolution, the environment plays a role in shaping the traits of organisms through the principle of use and disuse. Lamarck proposed that organisms could acquire or lose certain traits based on their interactions with the environment during their lifetime, and these acquired traits could be passed on to their offspring. This theory is known as the inheritance of acquired characteristics.
What were the two ideas proposed by Lamarck to explain the mechanism of evolution?
Jean-Baptiste Lamarck proposed two ideas to explain the mechanism of evolution: the inheritance of acquired traits and the use and disuse of organs. According to Lamarck, organisms could pass on traits they acquired during their lifetime to their offspring, and that the use or disuse of certain organs could lead to changes in those organs over time.
Who proposed that organisms acquired or lost traits during their lifetime by selective use or disuse of organs?
Jean-Baptiste Lamarck was the scientist who proposed the theory of acquired characteristics, suggesting organisms could acquire or lose traits during their lifetime through the use or disuse of certain organs. This theory was later replaced by Darwin's theory of evolution by natural selection.
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
What did Jean-Baptiste Lamarck believe?
Jean-Baptiste Lamarck believed in the theory of inheritance of acquired characteristics, which proposed that organisms could pass on traits that they acquired during their lifetime to their offspring. He also believed in the idea of evolution, suggesting that organisms change over time in response to their environment. However, Lamarck's ideas have been largely discredited in favor of Charles Darwin's theory of natural selection.
Which mechanism for evolution was proposed by lamarck?
The mechanism for evolution that was proposed by Jean Baptiste Lamarck was that organisms began life as primitive forms but adapted to their environment and became more complex forms. He also claimed that as time progressed, new primitive organisms were also occurring, so that they may evolve in the future.
