survival - those that live have the babies and their genetic profile is perpetuated. Those that die don't have offspring and therefore their genetic profile become extinct.
Well, there is a major difference between natural selection and "unnatural selection", as I call it. What you are talking about with selective breeding is what I call unnatural selection: An artificially imposed criteria for success. If you're trying to get a dog with blue stripes, a dog with blue stripes will be more likely to survive even though genetically it's most likely a dead end.
But I digress.
Natural selection/evolution works as follows: First you have the mutation, then the selection. Over the course of generations, you occasionally have mutations. These can be of a few types: fatal, semi-fatal, neutral or beneficial. Now, if the mutation is fatal or semi-fatal, then the creature in question will almost definitely not be able to reproduce and pass down this genetic flaw (except in humans, with our advanced medicine) so this mutation effectively destroys its own chance of making it into the gene pool. A neutral mutation would not make it any more or less likely for the creature to live or die, to breed or not breed, so it would effectively have no effect.
A beneficial mutation however, would improve its chances. So now you have a creature with a beneficial mutation. This could make its reaction time very slightly faster, or it breeds more quickly, or it has slightly better camoflage (keep in mind, mutations are ITERATIVE. This means they make very tiny adjustments to the creature, not big leaps). Now, if that creature does something better, theres a higher chance of it surviving and breeding. If it survives and breeds, its children inherit this advantage. If its children are successful too, then on it goes.
If repeated mutations make the resulting successful creature different enough, eventually you get a new creature, which goes down its own evolutionary path, separate from the creature it originally was generations ago.
And there you have it, evolution in a nutshell.

What does brief overview mean?
An "overview" is A survey or a broad, comprehensive view of something. A summary or a review of something. And the word "brief" means short. Thus a "brief overview" is a short (in length) summary of something.
What is the purpose for an abstract?
The purpose of an abstract is to give the reader a synopsis of what they are about to read. The abstract generally provides the details of the research including how the research was conducted.
What is research abstract?
A research abstract is a concise summary of a research paper or article that provides an overview of the study's purpose, methods, results, and conclusions. It is typically used to help readers quickly understand the key points of the research without having to read the full paper.

What is abstract in a presentation?
An abstract in a presentation is a brief summary of the main points or purpose of the presentation. It provides the audience with an overview of what to expect and serves as an introduction to the topic being discussed. The abstract should highlight the key takeaways and help the audience understand the significance of the presentation.
How do natural selection and sexual selection differ in their roles in shaping the evolution of species?
Natural selection and sexual selection are both mechanisms of evolution, but they differ in how they shape species. Natural selection acts on traits that affect an organism's survival and ability to reproduce in its environment, leading to adaptations that increase survival and reproduction. Sexual selection, on the other hand, acts on traits that affect an organism's ability to attract mates and reproduce, leading to the development of traits that enhance mating success. In summary, natural selection primarily influences survival and reproductive success in the environment, while sexual selection primarily influences mating success and reproductive opportunities.
How are selective breeding and natural selection similar how are they different?
In selective breeding the owners of the pets will choose mates that have selected characteristics that are wanted in the offspring. They may also be repeated with future offspring. In natural breeding it is natural selection that choose and in cats their may even be more than one father and different offspring. In summary the main differences are: Selective humans choose partners with named specific characteristics where as natural if often more first come first served. Also selective breeding is often carried on through the generations whereas natural does not. Similarities are after partners are choose the rest of the process is the same.
How do disruptive selection and directional selection differ in their impact on the evolution of a population?
Disruptive selection and directional selection are two types of natural selection that impact the evolution of a population in different ways. Disruptive selection favors extreme traits at both ends of the spectrum, leading to the divergence of a population into two distinct groups. On the other hand, directional selection favors one extreme trait, causing the population to shift towards that trait over time. In summary, disruptive selection promotes diversity within a population, while directional selection drives the population towards a specific trait.
What is the opposite of summary?
The opposite of summary is elaboration. While a summary provides a brief overview of something, elaboration involves expanding on the details and providing more in-depth information.
What role does research proposal play in the research process?
A research proposal is a document written by a researcher that provides a detailed description of the proposed program. It is like an outline of the entire research process that gives a reader a summary of the information discussed in a project.
What role does research proposal play in research process?
A research proposal is a document written by a researcher that provides a detailed description of the proposed program. It is like an outline of the entire research process that gives a reader a summary of the information discussed in a project.
What is in a summary?
a summary is a short or long (depending on the length of the selection) description about the main points of a passage To sum up all information that was stated in a shorter version.
What is an objective summary?
The objective summary provides an efficient way to preview information to use (or not) in a project or assignment. If you need an example, search "objective summary" on Google. Hope this helps.
Which screen provides a summary of important company information on quickbooks?
Company information
Which provides a preview or summary of what will be covered in the chapter?
The introduction of a chapter typically provides a preview or summary of the topics or key points that will be covered in that chapter. It gives readers a roadmap of what to expect and helps set the context for the upcoming content.
What is the difference between a summary and an abstract?
A summary provides a brief overview of the main points of a text, while an abstract is a concise summary of a research paper or article, highlighting the purpose, methods, results, and conclusions.
What is the process of evolution?
Charles Darwin, a scientist from the nineteenth century, was the creator of the theory (or law, if you wish) of evolution and its mechanism of natural selection. Let's start off with a definition: evolution is the process over time in which a species changes, for the better, in its traits in order to compete with other species. Evolution occurs via its mechanism, natural selection. According to natural selection, the fittest members of a species survive and produce offspring to whom they pass on their traits. Some members are born with mutations in their genes, and sometimes these are helpful. For example, an animal with a longer neck can reach stuff higher in a tree, meaning survival for it if there is no food at lower levels because of the others competing for it. So the surviving mutated animal gives birth and passes on its trait, which also survives, and passes it on, etc. Meanwhile, the others die out because they cannot compete with this super family of long necks. Over many generations, the only members left of the species are those with longer necks. This is, for example, how the giraffe's neck got so long over time. In basic summary, natural selection is the survival of the fittest. So over time, natural selection and competitition give way to a species evolving over time to make a species most adept at living in its environment. This is how evolution occurs.
