The origin of new species from already existing species over a period of time is called:
Correct answer: B. Evolution
- A. Adaptation
- B. Evolution
- C. Neo-Darwinsm
- D. Special creation
Explanation
Evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The evolutionary process by which a new species comes into being is called speciation.Evolution is the process of change in the heritable traits of biological populations over successive generations, leading to the diversity of life on Earth. It occurs through mechanisms like natural selection, where individuals with traits better suited to their environment are more likely to survive and reproduce, passing those advantageous genes to their offspring. Other processes include genetic mutations and variations that introduce new traits into a population.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
