How does chance play a role in evolution?
Evolution is caused by adaptations (favorable traits) that sometimes come from mutations. Mutations happen by chance, and this is how chance plays a role in evolution.
What is the best topic sentence for an article about whether or not certain genes play a favorable role in human evolution?
In the past century there will be a different classification of human evolution
How does biodiversity support evolution?
To have evolution, you must have random variation and differential reproductive success. Biodiversity represents the random variation found in a population. Natural selection, the way in which evolution works, does not create new traits. It only selects them and allows them to become more prevalent in the population. This happens because the organisms with the favorable traits are able to produce more offspring. Without biodiversity, these traits might not exist in the first place and so could not be favored.
How can genetic mutations support macro-evolution?
Mutations in an individuals germ line can be passed into progeny and if these mutations are beneficial then the allele frequency in the individuals population can change which is evolution. Over time and with many beneficial mutations against a favorable environment a population, or populations, most often geographically isolated, can change alleles so much that the two split populations can no longer interbreed and you have a new species; macro-evolution.
What are the basic driving forces behind evolution?
the driving forces behind evolution are Mutation, Natural Selection, Gene flow, and Genetic drift So lets start with Natural selection, all this means is that that individuals best suited for their environment are more likely to survive and reproduce. That's all it is, Individuals with certain inherited traits leave more off spring than others. an example of natural selection would be anti-biotic resistance in bacteria. Now mutations, Mutations are random and can be beneficial, neutral, or harmful to an organism, however not all mutations matter in evolution. only those that can be passed on to the next generation matter. Those that occur in somatic cells do not matter to evolution. Genetic drift - change in the gene pool of a small population due to chance. an example. Disasters such as the BP oil spill occur which kills off a large number of individuals, this results in a drastic reduction of the population size which in turn affects the genetic variation. and finally Gene flow which is when individuals migrate between populations, this brings in more genetic variation.
What is the difference between the meanings of the terms evolution and natural selection?
Evolution is the change in allele frequency over time in a population of organisms. Change over time and a fact. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms and explains much about the fact of evolution.

Is Fertilization is NOT possible outside the female reproductive system?
it is possible in labs........the procedure done is called artificial insemination where the sperm and egg are fused together under favorable conditions ...then it is deposited in the female reproductive systm
What is favorable reviews?
Favorable reviews are positive feedback or comments about a product, service, or experience. These reviews highlight the good aspects, strengths, or advantages of the subject being reviewed. They can influence others' opinions and contribute to building a positive reputation.
What is a favourable characteristic?
A favorable characteristic, or trait in evolutionary biology is some trait that allows the organism increased survivability and reproductive success. Even if it is only incremental success.
What is Darwin's great idea?
Survival of the fittest, the idea that if something has a favorable trait, it is more likely to survive and reproduce and pass on that trait. It is the basis of the modern evolution theory
What is the comparative of favorable?
more favorable
What are Filipino values favorable to economic development?
Filipino values favorable to economic development include hard work, resilience, resourcefulness, and strong family ties. These values contribute to a strong work ethic, adaptability to challenges, creativity in finding solutions, and support systems that can help individuals and communities thrive economically.
