When a population undergoes strong selection, individuals with advantageous traits are more likely to survive and reproduce, leading to an increase in the frequency of those traits within the population. This can result in rapid evolutionary changes as the population adapts to its environment.

What kind of selection occurs in many birds when males that build strong nests and help care for young are chosen by females as mates?
Sexual selection occurs, where females choose mates based on specific traits that may indicate genetic quality and fitness. In this case, the trait of building strong nests and helping care for young is being selected for in male birds by females, as it increases the chances of their offspring's survival. This selection process helps ensure that males with these advantageous traits pass them on to future generations.
Why does natural selection occurs too be more quickly?
A lot of natural selection occurs very slowly. It took the evolution of the dog from the wolf to take at least 14,000 years. It took singled celled life 3+billion years to evolve into multicellular life.
How do people know evolution really happens?
Because evolution is the change in allele frequency over time in a population of organisms and this is easily seen in population gene sequencing. This does not even mention fossils, genetics, developmental biology, geology and myriad other disciplines that support the fact of evolution. See related links for details.
Is natural selection a fact or theory?
Natural selection is a scientific theory proposed by Charles Darwin to explain how species evolve over time. It is based on strong evidence from observations and experiments, making it widely accepted as a fundamental mechanism of evolution.
What is the Hard shell covering the pupa?
The hard shell covering the pupa is called a chrysalis. It is formed when a caterpillar undergoes metamorphosis and transforms into a pupa before emerging as an adult butterfly or moth. The chrysalis protects the pupa as it undergoes this transformation.
How does environmental pressure affect natural selection?
When nothing happens to exert strong population pressure on that population, natural selection favors the allele frequency already present. When mutations cause new traits, natural selection weeds these traits out because they're not as efficient as the others.
What class of of salts undergoes hydrolysis?
These are the salts of strong acids and strong bases.
Which does natural Which does natural selection affect?
natural selection is basiclly only the strong survive which means it effects the weak by killing them but bernifits the strong
What is a strong character who undergoes a major change by the end of a story?

What happens to the variation in traits which are under strong natural selection?
It depends on which form is being favored by selection. In directional selection, one of the extremes of the "bell curve" has the advantage. In this case selection will "drive" the variation toward one end. Example: a population of birds where long, narrow beaks have an advantage; variation will be pushed toward longer, narrower beaks until that stops being advantageous. On the other hand, sometimes selection favors the "middle of the road" form. In this case, the variation will be driven toward the middle and the extremes will drop away. For example, a population of moths where a medium shade of coloring has the advantage (not too light or too dark); in this case, you'll get more gray moths, less black and white. This is "stabilizing selection".
