An example often given is the peppered moth. It has two forms, a light speckled one and a dark plain one. They often sit on tree trunks. Before the industrial revolution the speckled ones were well camouflaged against the lichen covered bark, and the dark ones were very conspicuous and got eaten by birds. Consequently there were far more speckled ones. When city air became full of smoke and soot the lichen died and the trunks became black. Now it was the speckled form that stood out and the numbers of black ones in cities went up. The trend has reversed again as we have burned less coal and cleaned up the environment.
It's important to remember that this is natural selection, but not yet evolution. Both forms of the moth are still being born. However it's possible to see that if the two different environments persisted for a long time then two distinct forms might come about which no longer interbred.

Why is the statement survival of the fittest often misunderstood?
The term "fittest" is not actually "fittest to survive" but rather "fittest to survive long enough to reproduce". If one animal lives 20 years, but has 15 offspring, and another lives on 5 years, but manages to have 50 offspring, the latter example would be considered fore "fit" by the standards of Darwin's statement.
Why is the phrase survival of the fittest wrong when it comes to natural selection?
The phrase "survival of the fittest" is often misunderstood because it can imply that only the strongest or most physically fit organisms survive. In reality, natural selection favors individuals with traits that are best suited to their environment, not just those that are the most physically fit. It's about the overall fitness of an organism in relation to its environment, not just physical strength.
What happens if the animal is not well adapted or fit (survival of the fittest)?
If an animal is not well adapted or fit for its environment, it may struggle to find food, evade predators, or reproduce effectively. This can lead to increased mortality rates and reduced population sizes over time. Ultimately, those individuals may not survive long enough to pass on their genes, leading to a gradual decline in the species' overall fitness within that habitat. In extreme cases, poor adaptation can result in extinction.
What may befall the least fittest?
The least fittest dies out and the group/population/species is replaced entirely by the fitter ones. In theory, this is to keep happening again and again with all traits until the group/population/species becomes perfect.
Why is competition among individuals of the same species so intense and how does it contribute to survival?
Limited resources, competition among individuals allows the most fit to succeed resulting in a stronger species
How the concept of the survival of the fittest relates to the theory of evolution?
Poorly - what was described (and what really happens) is the death of the less fit (as well as the unlucky). "Survival of the fittest" is a political slogan.
What happened to Devine Design?
survival of the fittest won, it wasnt fit so it didnt survive
Why is the statement survival of the fittest often misunderstood?

What describes hat survival of the fittest means?
Survival of the fittest is a concept in evolution where individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring. It does not necessarily mean the strongest or most physically fit survive, but rather those best adapted to their environment. This process leads to the gradual change and adaptation of species over time.
How do you use survival of the fittest in sentence?
Survival of the fittest means that the healthiest, most fit, most powerful animals survive.Though the phrase "survival of the fittest" began from scientists studying animal behavior, it was quickly adopted to describe human behavior and obstacles humans face.Technically, applying the definition of survival of the fittest to human situations, it would mean no one disabled would 'survive'. However, this is a myth that disabled persons are less able or deserving to survive.Many powerful people, such as those with high incomes, often use the excuse "survival of the fittest" to defend how they treat other people unfairly in business transactions."Survival of the fittest" is merely a metaphor and theory, not necessarily fact, though many people have come to believe it is always a fact.
Is the concept of 'survival of the fittest' a circular argument?
No. Because ' survival of the fittest ' is a highly inaccurate concept that is not considered empirically supportable. Fit individuals die; populations evolve by expressing the traits passed on by fit individuals. That fitness is environmentally in context dependent and a phrase like ' survival of the fittest ', while catchy, does not address the true issue of heredity.
What one phrase best defines evolution through natural selection?
Survival of the fittest. The group that is fit for it's environment will survive.
How does the survival of the fittest idea work?
The fit are those organisms in the immediate environment that have the adaptions that allow them to survive and reproduce successfully at a better rate than organisms not so fit.
How does the term natural selection relate to the common phrase survival of the fittest what does it mean to be fit?
It means the reproductively fittest organisms have offspring that carry the traits that made them reproductively fit. Remember, the fittest survive to reproduce, not the strongest. In some immediate environments, among humans, that could mean the richest, the funniest, the famous, or even the luckiest.
How does the survival of the fittest philosophy impact the evolution of species?
The survival of the fittest philosophy, also known as natural selection, impacts the evolution of species by favoring individuals with traits that help them survive and reproduce in their environment. Over time, this process leads to the adaptation and evolution of species to better fit their surroundings.
Can we apply the evolutionary concept 'survival of the fittest' to human beings?
Although since its development the human race has much depended on such survival - the fittest being those who could think to use what they had well enough, not just physically fit - it is now at the point where that intelligence allows us to surpass the problems of finding enough food and resources, of protecting ourselves from predators and of ensuring our health. Hence, survival of the fittest currently does not applies to humankind.
The Galapagos finch species is an excellent example of?
The Galapagos finches were studied extensively by Charles Darwin and were instrumental in his theory of evolution. They show adaptive radiation, meaning they evolved to fit different niches in their habitat.
