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.

Why is lamarck's theory not supported by the theory of natural selection?
Lamarck thought that traits organisms acquired during their lifetime would be passed on to offspring. He believed that traits were determined by use or disuse. However, acquired traits cannot be passed on to offspring; only traits determined by DNA can
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
How are traits passed from parents to their offspring?
Traits are passed by DNA.
How did Lamarck's ideas differ from Darwin's?
Lamarck believed an individual organism acquired traits during its lifetime and passed those traits on to its offspring. He lacked support for his ideas. Darwin documented how inherited traits could be passed on by natural selection, that adaptations that give an organism an advantage is passed on through subsequent generations and becomes more common. He had evidence for his ideas (finches, tortoises…).
How are simple inherited traits passed from parents to their offspring and then to the next generation?
Simple inherited traits are passed down because each parent contains genes which are given to their offspring. The offspring inherits or receives these traits. The offspring then passes down those traits to their offspring. Each time there is a new generation, the original trait becomes less evident. The recessive traits decrease by a certain percent every time a new set of genes are added.
Who proposed the acquired traits could be passed on to an organisms offspring?
Lamark
Who proposed that acquired traits could be passed on to an organisms offspring?
Jean-Baptiste Lamarck proposed the theory of inheritance of acquired characteristics. He suggested that organisms could pass on traits acquired during their lifetime to their offspring. This idea has been largely discredited in modern biology.
what is Adaptation about?
They are genetically acquired traits They are passed along to offspring
Is the process through which traits are passed from parent to offspring?
acquired characteristics
Who proposed that the selective use or disuse of an organ led to a change the organ that was then passed to the offspring?
Jean-Baptiste Lamarck proposed this idea in his theory of inheritance of acquired characteristics. He suggested that organisms could pass on traits acquired during their lifetime to their offspring, leading to evolutionary change.
Why is lamarck's theory not supported by the theory of natural selection?
Lamarck thought that traits organisms acquired during their lifetime would be passed on to offspring. He believed that traits were determined by use or disuse. However, acquired traits cannot be passed on to offspring; only traits determined by DNA can
Which is true about adaptions?
They are passed along to offspring.
Who proposed the idea of inheritance of acquitted characteristics?
Jean-Baptiste Lamarck, a French biologist, proposed the idea of the inheritance of acquired characteristics as part of his theory of evolution in the early 19th century. He believed that traits acquired during an organism's lifetime could be passed on to offspring.
Did Darwin or Lamarck hypothesized that characteristics developed by parents are passed on to their offspring?
?Mendel, widely acknowledged as the first geneticist.the answer is either lamarck or darwinit's lamarck. he believed that characteristics developed by parents are passed on to their offspring.
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
Does inheritance of acquired characteristics express the concept of natural selection?
No, the inheritance of acquired characteristics is a concept proposed by Jean-Baptiste Lamarck that suggests acquired traits during an organism's lifetime can be passed on to offspring. This idea differs from the concept of natural selection proposed by Charles Darwin, which emphasizes the role of genetic variation and selective pressure in driving evolutionary change.
Who is the French naturalist who hypothesized that organisms acquire traits during their lifetime through use or disuse which can be passed on to their offspring?
Jean-Baptiste Lamarck is the French naturalist who proposed the theory of inheritance of acquired traits, also known as Lamarckism. He suggested that organisms can pass on traits that they acquire during their lifetime to their offspring.
