Answer:
they considered valid but a certain idea of acquired characteristics being inherited was rejected
Explanation:
his theory was that if the environment demanded a need or use of a structure in an organism it developed it in response to demand leading to natural use or disuse of structures which he said that these new structures would be passed to their offspring leading to emergence of a new species. scientists accepted that the environment has a role in directing phenotypic changes in an individual taking a body builder for example since his muscles will become huge due to continuous use of the muscles in exercises
but scientists rejected his theory of these acquired characteristics were inherited since phenotypically acquired characteristics that do not affect the genotype of an individual can't be inherited

Answer;
Natural selection
Explanation;
-Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift.Genetic diversity allows the different organisms to have different physiological characteristics. Some of them provides them with genetic resistance, others don’t. The ones which are resistant survive the pesticide, others don’t ; this is known as natural selection.
-Those that are resistant will live longer and have a larger number of offspring (reproductive success). From one generation to another, there will be more and more resistant pests (because of their larger offspring), and less and less pests that are not resistant (because they tend to die young). If the selection process goes on, someday the pesticide will be useless (it will kill no pest).

does this come for a story or is just a question?
