Heritable variations play a crucial role in Darwin's theory of natural selection as they provide the raw material for evolution to act upon. These variations are inherited from parents to offspring and can affect an individual's ability to survive and reproduce in a given environment. Natural selection then acts on these variations, with individuals better adapted to their environment being more likely to survive and pass on their favorable traits to the next generation.
Yes, Darwin's theory of evolution by natural selection continues to be a fundamental principle in the field of biology and is widely accepted by the scientific community. It is used to explain the diversity of species and their adaptations to different environments.
First, he had no idea how heritable traits pass from one generation to the next. Second, although variation in heritable traits was central to Darwin's theory, he had no idea how that variation appeared.
Certain variations are more likely to be passed on to future generations than others, because those variations help their possessors reproduce more successfully. Other variations are less likely to be passed on because they do not help, or even hinder their possessors in successful reproduction. We say that the helpful variations are selected by the very nature of things. Without variation, whether an organism reproduces successfully or not is just a matter of blind chance. There is no natural tendency for certain individuals to be more successful at reproducing than others, because there are no differences between individuals.
Key concepts in Dumond's biology that are essential for understanding the principles of evolution include natural selection, genetic variation, adaptation, speciation, and the role of mutations in driving evolutionary change. These concepts help explain how species evolve over time through the process of natural selection acting on heritable traits.
Darwin said that artificial selection was when nature provided the variation, and humans selected those variations that they found useful. Inherited variations are differences that are passed from parents to offspring
The mechanism of heredity. His explanation, some sort of blending, was not supportable by the evidence and completely wrong We now know that heritable traits are particulate in nature.

Darwin explained his findings about the finches in the Galápagos Islands by proposing that they evolved from a common ancestor and adapted to different environments through natural selection. He observed variations in beak shapes among the finches that corresponded to their specific diets, leading him to theorize that these variations were the result of natural selection promoting traits that conferred a survival advantage in their respective habitats.

Evolution only deals with the changes within populations of organisms. All other sciences, including Astronomy and Cosmology, are mostly unconcerned with the theory. Otherwise, the theory was, and is, completely sound.
Variation is the introduction of new ideas or practices within an organization. Selection involves choosing which variations to retain based on their effectiveness. Retention involves integrating successful variations into the organization's practices. The process explains how innovation occurs by allowing for experimentation, evaluation, and adoption of successful new ways of doing things.
