Instead, Greene uses the 35-year-old evolutionary Tree of Life (TOL) classification system, which explains the diversity of life by matching and mapping relationships on a branching diagram or "tree." ...

How do scientists diagram evolutionary relationships? Scientists represent evolutionary relationships with tree diagrams (also called cladograms) because new life forms appear the way new branches ...

Play NOVA's Evolution Lab to explore the tree of life and become an expert in phylogenetics—the study of the evolutionary relationships among species. Opens in a new window.

The tree of life might seem like a stable design, appropriate for indelible ink. Plenty of people think so. An Internet search for “phylogenetic tattoos” turns up some showy skin art.

“A New Tree of Life” (2016); (B) a simplified version showing other major divisions. Incidentally, not reproducing doesn’t mean you’re not involved in the evolutionary process. Non-reproductive ...

“On the Origin of Species,” published twenty-two years later, includes only one diagram: an evolutionary tree. The tree of life became for biology what the periodic table was for chemistry ...

Birds are the most diverse land vertebrate on the planet, and now scientists have constructed a complete evolutionary tree of the 11,000 or so known species. This data came from hundreds of ...

Scientists in Darwin’s time and through most of the 20th century could only work out the branches of the evolutionary tree of life by looking at the structure and appearance of animals and plants.

They created a complete evolutionary tree of bird species by combining data on 9,239 species published in nearly 300 studies between 1990 and 2024 and additional curated data on another 1,000 species.
