Tree of life or Universal Tree of Life is a metaphor, model and research tool used to explore the evolution of life and describe the relationships between organisms, both living and extinct, as described in a famous passage in Charles Darwin’s On the Origin of Species (1859).
The affinities of all the beings of the same class have some-
times been represented by a great tree. I believe this simile
largely speaks the truth. — Charles DarwinTree diagrams originated in the medieval era to represent genealogical relationships. Phylogenetic tree diagrams in the evolutionary sense date back to at least the early 19th century. The term phylogeny for the evolutionary relationships of species through time was coined by Ernst Haeckel, who went further than Darwin in proposing phylogenic histories of life. In contemporary usage, tree of life refers to the compilation of comprehensive phylogenetic databases rooted at the last universal common ancestor of life on Earth. — Wikipedia

Science
Phylogenetics is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms.– Wikipedia

- AI opens new era in cognitive studies of wild...on August 1, 2026 at 8:00 pm
Scientists created an AI system that uses facial recognition and real-time touchscreen testing to automate cognitive studies of capuchin monkeys in the wild. The American Journal of Primatology published a proof-of-concept for the novel method—dubbed CapuchinAI—developed by researchers at Emory University and Georgia Institute of Technology.

Two organisms inhabiting a common environment can sometimes mutually influence each other, either benefiting or, in some cases, damaging one another. This mutually beneficial or ambivalent biological relationship is known as symbiosis.

Scientists have discovered a remarkably well-preserved 100-million-year-old beetle fossil that provides a rare glimpse into the evolution of the intricate sensory and communication systems used by fireflies and their relatives today. Fireflies belong to the order Coleoptera, which includes all beetles.
- Female birds have shorter lifespans than male...on July 30, 2026 at 10:30 pm
Birds have a lot to do in their short lives: defend territories, build nests, raise chicks and feed themselves. But the toll of these activities may be greater for female birds than for male birds. A new study by UCLA ornithologists has found that female birds have lower survival rates than males. The research is the first to study female bird survival in a large dataset and shows that the phenomenon is more widespread than previously recognized. In mammals, females generally have higher […]

UC Berkeley researchers have identified regions of DNA that humans inherited from two unknown ancestors as a result of long-ago interbreeding among modern humans and at least four other archaic human relatives.
