History of Phylogenetic Tree
Ancient beliefs of a ladder-like evolution from lower to higher life forms gave rise to the concept of a “tree of life”. A “paleontological chart” outlining the geological relationships between plants and animals can be found in Edward Hitchcock’s book Elementary Geology as one of the earliest examples of “branching” phylogenetic trees (first edition: 1840).
In his book ‘The Origin of Species’, Charles Darwin created one of the first pictures and played a significant role in popularising the idea of an evolutionary “tree.” The concept that speciation occurs through the adaptive and semi-random splitting of lineages is successfully communicated by tree diagrams, which are still used by evolutionary biologists to represent evolution more than a century after they were first used.

Phylogenetic Tree | Construction and Overview
A phylogenetic tree is a visual diagram that represents the history of the evolutionary descent of different species or genes from a common ancestor. The relationships are developed over time between different biological species based on the similarities and differences in their physical or genetic traits.
A phylogenetic tree is also known as an “Evolutionary tree” or “Dendrogram”. In this article, we will read about phylogenetic tree examples and construction in detail.
