Molecular taxonomy is a method of classifying organisms based on the analysis of genetic material, providing a more accurate and detailed understanding of evolutionary relationships than traditional morphological taxonomy. It utilizes techniques such as DNA sequencing to identify genetic differences and similarities among species, thereby refining the phylogenetic tree of life.

Molecular Taxonomy

Classifying organisms

Genetic material is the molecular basis of inheritance, encoding the information necessary for the development, function, and reproduction of living organisms. It primarily consists of DNA and RNA, which carry genetic instructions in the form of sequences of nucleotides.

Traditional morphological taxonomy

DNA sequencing is a laboratory technique used to determine the exact sequence of nucleotides within a DNA molecule, providing critical information for fields such as genetics, medicine, and biology. Advances in sequencing technologies have drastically reduced costs and increased speed, enabling large-scale projects like the Human Genome Project and personalized medicine applications.

Genetic differences

Genetic similarities

A species is a group of organisms that can interbreed and produce fertile offspring, sharing common characteristics and genetic makeup. The concept of species is fundamental in biology, aiding in the classification and understanding of biodiversity and evolutionary relationships.
