Phylogenetic Tree vs Cladogram
Phylogenetic trees and cladograms are frequently used interchangeably; however, they differ in some ways.
Feature | Phylogenetic Tree | Cladogram |
---|---|---|
Purpose | Shows evolutionary relationships and estimated time between divergences | Shows ancestral relationships and shared characteristics |
Time Scale | Often incorporates time scale on branches (represents evolutionary distance) | Does not depict time scale on branches |
Branch Length | Branch length may reflect time elapsed since divergence | Branch lengths are typically all the same length |
Ancestral Information | May depict ancestral characteristics at nodes | Does not depict ancestral characteristics |
Complexity | Can be more complex with detailed branching patterns | Generally simpler with fewer branches |
Information Source | Uses various data sources like DNA sequences, morphology, fossils | Primarily uses morphological data |
Evolutionary Certainty | Suggests relative evolutionary distances, but not necessarily exact timelines | Indicates shared ancestry but not the degree of evolutionary change |
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.
