Question

Write the reasons why the theory of gradual development of living organisms is followed by all.

Answer 1

1. Scientific Evidence: The theory of gradual development, particularly through natural selection, is supported by vast empirical evidence from palaeontology, morphology, and embryology.
2. Mechanism of Adaptation: It provides a logical, observable mechanism of natural selection that explains how organisms adapt to environmental changes over successive generations to survive.
3. Fossil Record Alignment: The chronological sequence of fossils found in different layers of Earth strata strongly aligns with the concept of gradual evolutionary changes over geological time.
4. Universal Acceptance: Proposed and refined by scientists like Charles Darwin, it successfully unifies diverse biological disciplines under a single coherent framework of life's history on Earth.
