FAQs on Darwin Diaries Class 7 Worksheet Buzzword
| 1. What was Charles Darwin's contribution to the field of science? |  |
Ans. Charles Darwin's most significant contribution was his theory of evolution through natural selection. He proposed that species evolve over time through the process of natural selection, where individuals with favorable traits are more likely to survive and reproduce, passing on their advantageous traits to future generations.
| 2. How did Charles Darwin gather evidence for his theory of evolution? | |
Ans. Charles Darwin gathered evidence for his theory of evolution through various means. He conducted extensive research, observed and collected specimens during his voyage on the HMS Beagle, and studied a wide range of scientific disciplines such as geology, zoology, and botany. He also corresponded with other scientists and conducted experiments to support his theory.
| 3. What is the main concept behind Darwin's theory of natural selection? | |
Ans. The main concept behind Darwin's theory of natural selection is that individuals within a population vary in their traits. Some of these traits are favorable for survival and reproduction in a particular environment, while others are not. Individuals with advantageous traits are more likely to survive and pass on their genes to the next generation, leading to the gradual evolution of species over time.
| 4. How did Darwin's theory of evolution challenge existing beliefs? | |
Ans. Darwin's theory of evolution challenged existing beliefs, particularly religious beliefs that held that species were fixed and unchanging. His theory proposed that species evolve and change over time through natural processes, rather than being created separately and remaining unchanged. This challenged the idea of divine creation and sparked debates about the origins of life.
| 5. What impact did Darwin's theory of evolution have on scientific thought? | |
Ans. Darwin's theory of evolution had a profound impact on scientific thought. It revolutionized biology and provided a unifying explanation for the diversity of life on Earth. It also influenced other fields such as anthropology, psychology, and even economics. Darwin's theory of evolution continues to be widely accepted and forms the basis of modern evolutionary biology.
