Darwin’s theory of evolution by natural selection fundamentally transformed our understanding of life on Earth and remains one of the most influential ideas in the history of science.

Darwin’s Theory of Evolution

Darwin proposed that species evolve over time through a process he called natural selection. According to Darwin, organisms within a population vary in traits, and those traits that confer advantages in a particular environment are more likely to be passed on to future generations. Over successive generations, these advantageous traits become more prevalent in the population, leading to the gradual evolution of species. Darwin’s theory provided a comprehensive explanation for the diversity of life and the adaptations of organisms to their environments. It challenged traditional religious and scientific views of the time and laid the groundwork for modern evolutionary biology.

Mendel’s Laws of Inheritance

In the same century, Gregor Mendel, an Austrian monk, conducted pioneering experiments in the field of genetics, laying the foundation for the science of heredity.

Mendel’s Laws of Inheritance

Mendel’s experiments with pea plants in the 1860s revealed the basic principles of inheritance. Through careful breeding experiments and statistical analysis, Mendel formulated two fundamental laws of inheritance:

1. The Law of Segregation: During gamete formation, the alleles for each gene segregate from each other so that each gamete carries only one allele for each gene.
2. The Law of Independent Assortment: Genes for different traits are inherited independently of each other.

Mendel’s work provided the first quantitative explanation for how traits are passed from parents to offspring and laid the groundwork for modern genetics. However, Mendel’s discoveries went largely unnoticed until the early 20th century when they were rediscovered and integrated into the emerging field of genetics, leading to a revolution in our understanding of heredity and inheritance patterns.

The 19th century revolution in biology, characterized by Darwin’s theory of evolution and Mendel’s laws of inheritance, transformed our understanding of the natural world and laid the foundation for modern biology. These groundbreaking discoveries provided the framework for future research and continue to shape our understanding of life and its diversity.
