What else can I help you with?
What replace Lamarck's theories?
lamarckism
Why was lamarckism discredited?
Because even back then they still knew enough about things to know that his theory was absurd.
What is Lamarckism?
Lamarck give the idea that an organism can pass on characteristics that it acquired during its lifetime to its offspring. Also known as heritability.
Why would you choose Natural Selection over Lamarckism?
Creationism should be chosen over those two any day.
Is lamackism and Darwinism compatible and how?
Lamarckism and Darwinism are not compatible because they propose different mechanisms for evolution. Lamarckism suggests that acquired traits can be passed down to offspring, while Darwinism proposes that natural selection acting on inherited variations drives evolution. The evidence overwhelmingly supports Darwinism as the main mechanism for evolution.
The statement Improving the intelligence of an adult through education will result in that adult's descendants being born with a greater native intelligence is an example of?
It is an example of Lamarckism.
What is the term for the theory stating that characteristics acquired during the lifetime off an individual could be passed on to that individuals offspring?
The term for this theory is Lamarckism, named after the French biologist Jean-Baptiste Lamarck. According to Lamarckism, traits acquired during an individual's lifetime can be inherited by their offspring. This concept has been largely discounted in modern biology in favor of the theory of inheritance through genetic material.
What is weismans experiment to disprove lamarckism?
August Weismann disproved, or attempt to disprove the theory of Lamarckism (which states that: the adaptive trait gained by an organism during its life time can transfer to the new generation of organism; in contrast, proponents of this theory states: changes to genes can only be done through natural selection, and the experiences of changes to an organism's genes during its life time does not transfer), by cutting off the tails of mice, for many generations to observe changes to their traits. However, after many generations, no changes to the tail lengths of mice were observed. Thus, with this experiment and many that followed it, most considered Lamarckism to be disproved. However, during recent years, Lamarckism has garnered considerable interests, as observations have shown that Lamarckism does exist. For example, the epidemics of the population whose previous generation has experienced starvation is more likely to produce children, who, for generations, is likely to have genes with higher risk of high blood pressure.
What are the three theories of evolution?
In the scientific sense of the word 'theory' (ie. testable explanatory model), there is just the one theory of evolution: evolutionary theory, which incorporates the central theses of common descent and natural selection.
What does evolution not involve?
Evolution does not involve individuals changing to better adapt to their environment during their lifetime (Lamarckism). It also does not involve a predetermined or goal-directed process. Furthermore, it does not always result in the creation of "perfect" or "advanced" organisms.
Who was the theory that the frequent use of an organ caused it to be enhanced was developed by?
The theory that the frequent use of an organ caused it to be enhanced was developed by Jean-Baptiste Lamarck, a French biologist. This theory is known as "Lamarckism" and suggests that acquired traits can be inherited.
What is Lamarck's theory?
Lamarck's theory, known as Lamarckism, proposed that organisms could pass down acquired traits to their offspring. He suggested that an organism could change during its lifetime in response to its environment and these changes would be inherited by its offspring. However, this theory has been largely discredited in modern biology.
