Introduction
Molecular phylogeny is a pivotal field within evolutionary biology that seeks to unravel the intricate web of relationships between different species. Unlike traditional taxonomy that relied on morphological characteristics, molecular phylogeny uses genetic and molecular data to construct evolutionary trees, providing a more accurate and nuanced depiction of evolutionary history. The field s significance lies in its ability to shed light on the common ancestry, divergence times, and evolutionary paths of organisms, ultimately unveiling the grand narrative of life on Earth.
History
The journey of molecular phylogeny is intertwined with the history of evolutionary thought. While pioneers like Charles Darwin laid the conceptual groundwork for the concept of common ancestry, it wasn t until the mid-20th century that technological advancements paved the way for molecular investigations. The discovery of the DNA double helix structure by Watson and Crick in 1953 marked a watershed moment, unlocking the molecular code of life and paving the way for molecular phylogeny.
