https://elearnportal.science/wiki/15_Things_Youre_Not_Sure_Of_About_Evolution_Blackjack of Evolution The theory of evolution is founded on the fact certain traits are passed on more frequently than others. These traits make it easier for individuals to reproduce and survive and thus increase in number over time. Scientists have a better understanding of how this process functions. A study of the clawed-frog revealed that duplicate genes can serve different purposes. Evolution is a process that occurs naturally The natural process resulting in the evolution of organisms best adjusted to their environment is referred to as "natural selection." It's one of the basic mechanisms of evolution, alongside mutation or migration as well as genetic drift. The ones with traits that help reproduction and survival are more likely to pass these traits to their children, which results in gradual changes in gene frequencies over time. This leads to the formation of new species and transformation of existing species. Charles Darwin developed a scientific theory in the early 19th century that explains how organisms developed over time. The theory is based on the notion that more offspring than could be able to survive are born and that these offspring compete for resources in their environments. This results in an "struggle for survival" in which the ones with the most beneficial traits win, and others are eliminated. The remaining offspring pass on the genes that confer these advantageous traits to their offspring which gives them an advantage over other members of the same species. As time passes, the number of organisms possessing these beneficial traits grows. However, it's difficult to understand how natural selection can create new characteristics if its main function is to eliminate unfit individuals. Additionally that, the majority of natural selections decrease genetic variation within populations. Natural selection is not likely to create new traits without the involvement o
