2. Natural Selection Theory
Charles Darwin’s theory of evolution by natural selection is one of the most important and well-known ideas in the field of biology.
Proposed in 1859, this theory explains how species change over time through the process of “natural selection.” According to the theory, organisms that possess traits that are advantageous to their environment are more likely to survive and reproduce, passing these advantageous traits on to their offspring.
Over time, this process leads to the evolution of new species and the adaptation of existing species to their environment.
The theory of evolution by natural selection has had a profound impact on the field of biology and has provided a framework for understanding the diversity of life on Earth.
In the following section, we will explore the details of Darwin’s theory and its importance in biology.
3. Cell Theory
The discovery of the cell is a landmark achievement in the field of biology that has had a lasting impact on our understanding of life.
In 1665, Robert Hooke made the first known observation of cells while examining a thin slice of cork under a microscope.
His discovery of these small, compartmentalized structures, which he referred to as “cells,” marked the beginning of modern cell biology.
The significance of Hooke’s discovery cannot be overstated, as it provided the first glimpse into the fundamental unit of life and laid the foundation for our understanding of the structure and function of cells.
