What else can I help you with?
What comes first mutation or natural selection?
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
Why Over time why does natural selection continue to work?
Natural selection creates a stronger species that is able to live longer and produce more. It continues to work because after a few generations, the traits will become common in the population.
Why does natural selection not directly affect genes?
Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this interaction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.
When was natural selection accepted?
Natural selection was formally accepted as a major mechanism of evolution in the 19th century with the publication of Charles Darwin's seminal work "On the Origin of Species" in 1859. However, the concept of natural selection was not widely accepted until later in the 20th century when more evidence in support of the theory accumulated.
How many parts does the process of natural selection have?
The process of natural selection has three main parts: variation, heredity, and differential reproductive success. These parts work together to drive evolutionary change in populations over time.
Time why does natural selection continue to work?
Natural selection creates a stronger species that is able to live longer and produce more. It continues to work because after a few generations, the traits will become common in the population.
What are three gradual process that change species overtime?
Natural selection, gene flow and genetic drift, though drift can work rather quickly.
Why does natural selection continue work over time?
Natural selection creates a stronger species that is able to live longer and produce more. It continues to work because after a few generations, the traits will become common in the population.
What comes first mutation or natural selection?
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
Why does natural selection work on organisms phenotypes rather than their genotypes?
This is backward, natural selection works on genotype not phenotype.
How does natural selection work for or against an organism?
Natural selection reduces the number of fertile offspring an organism may raise.
Does natural selection work on a variation already present in a population?
Yes.
Why was Charles Darwin work important?
because he created the natural selection
Why Over time why does natural selection continue to work?
Natural selection creates a stronger species that is able to live longer and produce more. It continues to work because after a few generations, the traits will become common in the population.
Who proposed a theory of evolution by natural selection similar to Darwin?
Alfred Russel Wallace, a contemporary of Charles Darwin, independently proposed a theory of evolution by natural selection that was similar to Darwin's. Wallace's work on natural selection prompted Darwin to publish his own views on the subject. The two scientists jointly presented their work in a paper in 1858.
Evolution by natural selection works best on populatin having no variation?
Evolution by natural selection actually relies on variation within a population. Without variation, there would be no genetic differences for natural selection to act upon, leading to no evolution. Variation provides the raw material for natural selection to work with, allowing beneficial traits to be favored and passed on to future generations.
When is overtime?
Overtime is work done outside your normal daily hours. If you normally work an eight hour day, but work an extra hour one day. That extra hour is overtime, and overtime is often paid at a higher rate.
