The co-discoverer of the theory. Wallace and Darwin gad their papers read out together at a 1858 meeting of the Linnaen Society in London.
It is not a matter of agreement, it is a matter of accepting the overwhelming evidences in support of the theory of evolution by natural selection.
In Darwin's theory of evolution by natural selection, the environment is a key driver of the process. Organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation. Environmental pressures, such as competition for resources or changes in climate, drive the process of natural selection by selecting for traits that increase an organism's fitness for survival.
Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.
It didn't, actually. While natural selection isn't the complete story of evolution, it is the single most important part of it, and all discussions of evolution must inevitably involve natural selection in some form.
There is no " what do I understand by the term evolution. " Evolution is the change in allele frequency over time in a population of organisms. This is a observed and observable fact. It is no longer Darwin's theory of evolution by natural selection, but has had over 150 years of modification and improvement to become the modern synthesis. A short definition of natural selection. " The non-random survival of randomly replicating organisms. "
Acquired traits. The theory of evolution by natural selection focuses on inherited traits that provide a reproductive advantage. Acquired traits, which are not genetically determined, do not play a direct role in this process.

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.
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.

The theory of modern synthesis, also known as neo-Darwinism, combines Darwin's theory of natural selection with modern genetics. It explains how evolution occurs through changes in the genetic makeup of populations over time. This theory emphasizes the role of mutations, genetic drift, gene flow, and natural selection in driving evolutionary change.

In Darwin's theory, natural selection plays the key role. Organisms vary through random mutations--slight changes from their parents. The environment determines which are most likely to survive. In Lamarck's theory, changes in phenotype are inherited. This is now known to be (largely) incorrect.
Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.

Meiosis plays a role in the process of natural selection by generating genetic diversity through the shuffling of genes during the formation of gametes. This genetic diversity contributes to variation within a population, which is crucial for natural selection to occur as individuals with advantageous traits are more likely to survive and pass on their genes to the next generation.
