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
Natural selection
Random processes are not part of the theory of evolution by natural selection.
Charles Darwin
Natural selection is most closely related to Darwin's theory of evolution.
According to evolutionary theory, natural selection is the principle that directs evolution.
Nice? The theory of evolution by natural selection is the best and best supported explanation for the fact of evolution we have, but it just is and a word such as " nice " would not always fit theory. Google Ichneumon wasp to see that natural selection is not always " nice. "
Later evidence from genetics and molecular biology showed that acquired traits are not passed down through generations as proposed by Lamarck, as they do not alter the genetic material. On the other hand, Darwin's theory of natural selection was supported by the discovery of the mechanism of inheritance through genes and DNA, providing a more robust explanation for evolutionary change over time.
Evolution by natural selection is called a theory because it is a well-supported and widely accepted explanation for how species change over time. In scientific terms, a theory is a comprehensive explanation that is supported by a large body of evidence from multiple fields of study. Despite being called a theory, the evidence for evolution by natural selection is overwhelmingly strong.
The Grants have been able to provide clear evidence for natural selection and supported Darwin's theory. The hypothesis was that natural selection can occur many times in a lifetime.
It does not mater what anyone thinks about the theory of evolution by natural selection. The theory of evolution by natural selection is the best explanation we have for much of the observed and observable fact of evolution. The theory is internally consistent with the fact of evolution, it is supported by myriad lines of converging evidence and it generates testable predictions in the form of scientific hypothesis. The opinion of no one is needed by the theory of evolution by natural selection and educated people have come to accept the theory.
Artificial selection demonstrated that desirable traits could be purposefully selected and passed down in domesticated plants and animals. This helped Darwin understand that similar processes could occur in nature through natural selection, where organisms with advantageous traits are more likely to survive and reproduce. This supported his theory of evolution by natural selection.

Evolution is considered a scientific theory because it is a well-supported explanation of how species change over time through natural selection. In science, a theory is an explanation that has been rigorously tested, supported by evidence, and can make accurate predictions about the natural world. Evolution meets these criteria, hence it is considered a solid scientific theory.
