Having one theory is setting a limit on your potential and the potential of the overall theory and subject you are working on. Having multiple theories gives you a broader idea and perspective of what is going on, and even though one may slightly contradict the other, it is okay because that is what theories are for.
To the point, scientists usually have more than one theory so that they can gain a broader perspective on the matter and maybe even increase the chance of being correct on the matter.
Hope this was helpful.

the organisms have varying traits, like different colored eggs because of the natural selection.
<h3>What is the process of natural selection? </h3>
Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.
the color change of an egg occurs by natural selection and also by genetic variability. since the environment will select the best ones to survive and mutations will occur. Natural selection will forcefully change the environment causing only a few species to survive.

Answer:
The transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization. It can be transferred by things that feed from what has pollen. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
