Molecular Biology
A phylogenetic tree is a diagram that represents the evolutionary relationships among various biological species or entities based on similarities and differences in their physical or genetic characteristics. These trees illustrate how species diverged from common ancestors over time, helping to visualize evolutionary pathways and the concept of descent with modification. Understanding these trees is essential for analyzing molecular clocks, which estimate the timing of evolutionary events, as well as for applying molecular phylogenetics in fields such as conservation biology and disease research.
