Evolution
Evolution is the process by which the genetic composition of a population of living organisms changes over time. Evolution occurs when some individuals in a population have traits that are better suited to their environment than others. These individuals are more likely to survive and reproduce, passing on their advantageous traits to their offspring.
Key Principles of Evolution
- Variation:Individuals in a population vary in their traits.
- Inheritance:Traits are passed down from parents to offspring.
- Selection:Individuals with traits that are better suited to their environment are more likely to survive and reproduce.
Role of Natural Selection in Evolution
Natural selection is the driving force of evolution. Natural selection occurs when individuals with certain traits are more likely to survive and reproduce than individuals with other traits. Over time, this can lead to significant changes in the genetic composition of a population.
Examples of Evolution
Evolution has shaped the diversity of life on Earth. Some examples of evolution include:
- The evolution of antibiotic resistance in bacteria.
- The evolution of pesticide resistance in insects.
- The evolution of new species, such as the peppered moth.
Mutation
Mutation is a change in the DNA sequence of an organism. Mutations can be caused by a variety of factors, including exposure to radiation, chemicals, and errors during DNA replication.
Types of Mutations
- Point mutationsare changes in a single nucleotide.
- Insertionsare the addition of one or more nucleotides to a DNA sequence.
- Deletionsare the removal of one or more nucleotides from a DNA sequence.
Causes and Consequences of Mutations
Mutations can have a variety of consequences, depending on the type of mutation and the location of the mutation in the DNA sequence.
- Some mutations are harmful and can lead to genetic disorders.
- Some mutations are beneficial and can provide an organism with an advantage in its environment.
- Most mutations are neutral and have no effect on the organism.
Role of Mutations in Evolution
Mutations are the raw material for evolution. Mutations provide the variation that is necessary for natural selection to work.
Selection
Selection is the process by which individuals with certain traits are more likely to survive and reproduce than individuals with other traits. Selection can be either natural or artificial.
Types of Selection
- Natural selectionis the process by which individuals with traits that are better suited to their environment are more likely to survive and reproduce.
- Artificial selectionis the process by which humans select for certain traits in plants and animals.
Role of Selection in Evolution
Selection is the driving force of evolution. Selection leads to changes in the genetic composition of a population over time.
Examples of Selection, Gizmo answer key evolution mutation and selection
Some examples of selection include:
- The evolution of antibiotic resistance in bacteria.
- The evolution of pesticide resistance in insects.
- The evolution of new species, such as the peppered moth.
| Concept | Definition | Types | Significance |
|---|---|---|---|
| Evolution | Change in genetic composition of a population over time | Natural, artificial | Drives diversity of life |
| Mutation | Change in DNA sequence | Point, insertion, deletion | Provides variation for evolution |
| Selection | Individuals with advantageous traits survive and reproduce | Natural, artificial | Drives changes in population genetics |
