Artificial Selection

Understanding artificial selection requires examining multiple perspectives and considerations. What would be the short- and long-term consequences of ... Let's sidestep the political and ideological issues surrounding artificial selection for now to focus on the scientific viability of it. Questions: Does artificial selection really work in animals and plants? If so, why wouldn't it work in humans?

Aren't humans analogous to other mammalian species from a selective breeding perspective? And how would we know the short- and long-term ... From another angle, can Artificial Selection create a New Species? : r/evolution - Reddit. That isn't the only way we delineate species. Additionally, this is Ernst Mayr's Biological Species Concept, but it's only applicable in a handful of species.

There are plants that can cross breed into other subtribes, and most sexually reproducing species can and often do hybridize ... Artificial selection doesn’t exist : r/evolution - Reddit. Artificial selection is a deliberate, conscious decision to increase or decrease the frequency of a specific trait in a population. It is arguable that artificial selection is a type of natural selection, but it has a specific, unambiguous, and useful definition. Artificial Selection: Two Pros And Cons Of Artificial Selection.

To begin, natural selection and artificial selection are drastically different. Natural selection is the process by which varied traits that increase survival and enable reproduction are passed down from one generation to another generation. Natural selection is where all species have some sort of involvement with the environment that they live in. Natural selection and artificial selection or selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene.

In relation to this, what counts as "genetic modification"? : r/biology - Reddit. Artificial selection modifies gene frequency in the population, but not genes themselves. Genetic modification introduces novel variations and/or skips selection to knock out or turn on a feature. Similarly, this allows you to surpass what is possible in the same amount of time via artificial selection. Is selective breeding considered evolution?

Short answer is yes, evolution as a concept encompasses natural and “artificial” selection/breeding, but as is usual, it can get complex. The difference to note is that under “natural” conditions, an organism’s ability to survive and reproduce determines what balance of beneficial/harmful mutations gets passed on, while under “artificial” selection, the mutations selected are for ... why does selective breeding speed up the evolutionary process so ....

Two important factors are at play here: the vastly greater strength of artificial vs natural selection, and the fact that visual distinctiveness is not a good indicator of genetic divergence.
