What Is the Definition of Evolution? Understanding Species Change Over Time

Discover the definition of evolution and learn how species change through genetic variations and natural selection over generations.

36 views

Evolution is the process through which species of organisms undergo changes over time due to genetic variations and natural selection. This transformative process leads to the emergence of new species, adaptations, and diversification within the biosphere. At its core, evolution explains the rich diversity of life on Earth and how organisms adapt to their environments over generations.

FAQs & Answers

  1. What is evolution in simple terms? Evolution is the process where species change over time due to genetic differences and natural selection, leading to new adaptations and sometimes new species.
  2. How does natural selection affect evolution? Natural selection favors organisms better adapted to their environment, allowing them to survive and reproduce, which drives evolutionary change.
  3. Why is evolution important for biodiversity? Evolution creates the diversity of life on Earth by enabling species to adapt to their environments and form new species over time.
