How would you explain evolution through natural selection?

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

What are the steps of natural selection how does this help show evolution?

Darwin’s process of natural selection has four components.

1. Variation. Organisms (within populations) exhibit individual variation in appearance and behavior.
2. Inheritance. Some traits are consistently passed on from parent to offspring.
3. High rate of population growth.
4. Differential survival and reproduction.

What is evolution explain with example?

Evolution in organisms occurs through changes in heritable traits—the inherited characteristics of an organism. In humans, for example, eye colour is an inherited characteristic and an individual might inherit the “brown-eye trait” from one of their parents.

What is selected during natural selection?

What is “selected” during natural selection? Individuals with certain advantageous traits are selected, in the sense that they produce the most offspring. c. Advantageous traits are selected, in the sense that they become more common in the population over time.

What are some examples of environmental changes that could create selection pressures for a species?

Predation, competition and disease are examples of selection pressures.

What are different types of natural selection explain with suitable examples?

Types of natural selection: Different types of natural selection can impact the distribution of phenotypes within a population.In (a) stabilizing selection, an average phenotype is favored.In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed.In (c) diversifying selection.
