Why was variation the weakest concept in Darwin's theory?
Variation?!?! That was an obvious observation of naturalists that opposed Darwin's concepts totally. Unless you mean the heritability that leads to variation? Explaining that variation was the problem. Creationists of the time explained this by positing god's whimsy in designing his species, but this was shown to be nonsense as natural processes are at work in variation and this can be shown experimentally. The concept of natural selection explained how that natural variation was selected on beneficial traits. What Darwin did not understand is how that variation was passed on to progeny. His explanation was wrong.
12. Which is not one of Darwin's four main ideas of natural selection?
Inheritance of acquired characteristics is not one of Darwin's four main ideas of natural selection. His four main ideas are variation, competition, heritability, and differential reproductive success.
Condition #1 of Darwin's Theory of Natural Selection by Descent with Modification states?
Individuals within a population have differences.
Which is not part of darwins theory of natuarl selsction?
The idea that evolution is a directed process with a predetermined goal or purpose is not part of Darwin's theory of natural selection. Instead, Darwin proposed that evolution occurs through random variation and selection based on the fitness of individuals in a given environment.
What of Mendels conclusions is a necessary foundation for Darwins theory of natural selection?
Mendel's conclusion on the segregation and independent assortment of traits laid the groundwork for Darwin's theory of natural selection by providing a mechanism for how variation is passed down from one generation to the next. This understanding of how traits are inherited allowed Darwin to propose that natural selection acts on this variation to drive the evolution of populations.
What are the four parts of Darwin's theory of natural selection?
Overproduction, genetic variation, selection, and adaption

What is variation under domestication of Darwin?
Artificial selection.
How is natural variations used in artificial selection?
Natural variation in artificial selection is used because humans choose from among the naturally occurring variation s in species. Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.

When was natural selection invented?
Natural selection was not "invented" but rather proposed as a mechanism for evolution by Charles Darwin in his book "On the Origin of Species" published in 1859. Darwin's theory of natural selection suggests that species evolve over time through the process of variation, inheritance, and differential survival and reproduction of individuals with advantageous traits.
What did Charles Darwin used the least to support natural selection?
Charles Darwin used data on artificial selection the least to support his theory of natural selection. While artificial selection played a role in shaping his understanding of how traits can change over generations, he focused primarily on observations of variation in nature and the role of competition and adaptation in driving the process of natural selection.
What is a key part of Darwin's idea of natural selection?
A key part of Darwin's idea of natural selection is the concept of variation among individuals within a population. Darwin proposed that individuals with traits that are better adapted to their environment are more likely to survive and reproduce, passing on these advantageous traits to the next generation.
