Evo in the news: More than morphology
This news brief, from August 2006, describes recent research on T. rex, with a special focus on how paleontologists move beyond the shape of the animal's bones to learn about aspects of its life that don't fossilize very well: its physiology, sensory abilities, and population dynamics.

- Life forms of the past were in some ways very different from living forms of today, but in other ways very similar.
- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
- The fossil record provides evidence for evolution.
- There are similarities and differences among fossils and living organisms.
- A hallmark of science is exposing ideas to testing.
- Scientists test their ideas using multiple lines of evidence.
- Scientists can test ideas about events and processes long past, very distant, and not directly observable.
- Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence.
- Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data.
- Our knowledge of the evolution of living things is always being refined as we gather more evidence.
- Scientists use fossils (including sequences of fossils showing gradual change over time) to learn about past life.
