The Tree of Life is a metaphorical representation of the interconnectedness of all living organisms on Earth. It illustrates how different species share common ancestors and evolve over time through the process of evolution. This concept is often depicted as a branching tree, where each branch represents a different species, and the trunk symbolizes the shared origins of life. In scientific terms, the Tree of Life is supported by various fields, including genetics, paleontology, and molecular biology. Researchers use DNA analysis to trace the relationships between species, helping to map out the evolutionary pathways that have led to the diversity of life we see today.
