Explain how each of the following can lead to the evolution of a population. a. Mutation – introduces new genes into the population and may cause phenotypic change that can be acted on by natural selection b.

The continual branching and independent evolution of new genetic lineages has led to the diversity of life. After diverging from a common ancestor, independently evolving lineages may accumulate many trait changes through natural selection acting over the course of many generations. Differences accumulate over time. Evolutionary time is immense.

Evolution and Natural Selection The process of biological evolution can be accurately defined as “descent with modification.” This definition includes microevolution (changes in allele frequency of a population over time) and macroevolution (the descent of different species from a shared common ancestor over many generations).

Hold it! Mutation-selection in biblical perspective? Isn’t that some sort of contradiction in terms? Not at all. Like thousands of other scientists (including many evolutionists), I think the scientific evidence is quite clear: Evolution demands an increase in the quantity and quality of genetic information, and mutation-selection, no matter how long you wait, cannot provide it.
Mutations are random Mutations can be beneficial, neutral, or harmful for the organism, but mutations do not "try" to supply what the organism "needs." In this respect, mutations are random — whether a particular mutation happens or not is unrelated to how useful that mutation would be. Not all mutations matter to evolution

The problem is that the only beneficial mutations ever observed do not add new information to the genome. Mutations in Viruses. This study illustrates the fact that natural selection can operate on a series of mutations and even on other organisms to produce a population change with a noticeably new characteristic. Yet for all that, the result

Students proceed through a series of presentation slides that include background information, examples, and embedded video, and
The process of evolution occurs only in populations and not in individuals. A single individual cannot evolve alone; evolution is the process of changing the gene frequencies within a gene pool. Five forces can cause genetic variation and evolution in a population: mutations, natural selection, genetic drift, genetic hitchhiking, and gene flow.
Explore natural selection by controlling the environment and causing mutations in bunnies.
· Not all mutations lead to evolution. Only hereditary mutations, which occur in egg or sperm cells, can be passed to future generations and potentially contribute to evolution. Some mutations occur during a person’s lifetime in only some of the body’s cells and are not hereditary, so natural selection cannot play a role.

Recipe for Natural Selection. This video introduces natural selection and the three key ingredients through which it effects change over time: the trait must vary in the population, it must be heritable, and individuals with a certain variation must have a reproductive advantage over those that do not.
