We do not know. It takes so long that in the almost 150 years since Darwin first proposed it as a theory, we have yet to see an example in action.

Natural selection can take a long time to produce noticeable results because it relies on changes in the gene pool of a population over successive generations. The process involves incremental shifts in allele frequencies and relies on factors such as genetic variation, environmental pressures, and reproductive success. These changes accumulate slowly over time as individuals with advantageous traits have more offspring, leading to the evolution of new traits in a population.

How long does it take to get results from a seismic survey?
The time it takes to get results from a seismic survey can vary depending on the size and complexity of the survey. Generally, it can take anywhere from a few weeks to a few months to process and interpret the data collected during the survey.
What is another word for urbanization?
"Urbanization" can also be referred to as "urban development" or "urban growth."
What time of day do most people take an enema?
People typically take an enema in the morning, as it is often recommended to do so on an empty stomach for best results. However, the timing can vary based on individual preference and what works best for their schedule.
Why does it take so long to fall asleep?
Difficulty falling asleep can be caused by stress, anxiety, poor sleep hygiene, or underlying sleep disorders. Also, factors such as excessive caffeine intake, irregular sleep schedules, and electronic device usage before bed can disrupt the body's natural sleep-wake cycle. It's important to establish a calming bedtime routine and create a comfortable sleep environment to promote faster sleep onset.
As opposed to dry pavement when the roadway is wet it will take your vehicle on average how long to stop?
On wet pavement, it will take your vehicle about twice as long to stop compared to dry pavement. This is due to reduced tire grip and increased distance needed for braking on wet surfaces. Drive cautiously and leave extra space between cars to account for longer stopping distances in wet conditions.
Was it absolutely necessary for natural selection to take place?
Genetic change is necessary for natural selection to take place
Natural selection need in order to take place?
Natural selection needs competition in order to take place.
How long does the process of natural selection and evolution take?
Evolution is a continuous, non-cyclical process that happens as long as there is life.
Why is natural variation important when it comes to evolution?
Only in the sense that natural selection needs variations in organisms to select from. Evolution could take place by random processes, such as genetic drift, or geographic processes, such as gene flow, but only natural selection causes the adaptive change that results in speciation.
Where did natural selection take place?
Everywhere where there is life.
How long does it take for adaptations to occur with natural selection?
Individual animals do not adapt. Adaptation happens over generations within a species in a certain environment.

How is a population different after it has experienced natural selection?
A population is different after natural selection because some of the negative genes have been weeded out. By experiencing natural selection things like obesity, weakness, and disease will be cut from the genetic pool (after many generations of coarse). Take a look at the Nam family to get a good example of this.
