What Did a T-Rex Taste Like, Summary

Summary of “What Did T-Rex Taste Like”

Folder 1: This folder teaches students that although life is very diverse, they are also connected. The different variety of plants, animals, organisms all come from a millions of years old process called, evolution. In the diagram that is presented, it is divided in to three sections labeled, bacteria, eukaryota, and archaea.

All these organisms are related and can be traced back in time through lineages to a common ancestor. An example that is shown is the lineage of the couple James and Frances. As their family keeps reproducing, family resemblances or (phenotype) are passed on to the next generation. The closer the generations are, the more resemblances they share. For example, Max being the latest generation may share similar phenotypes to his parents, but those similarities decrease once you compare Max to his grandparents or great-grandparents. Although this is just one family, this illustrates the idea all life streaming from one common ancestor.

Bacteria: “are single-celled organisms that have been around for more than 3.5 billion years. Bacteria can be found almost everywhere, from the base of your eyelashes to the deep layers of the Earth.”

Eukaryota: “include the organisms that people are most familiar with — animals, plants, fungi, and protists. They have a cell structure that includes a nucleus and other organelles. They can be single-celled or multi-celled.

Archaea: “very unusual microscopic, single-celled organisms. They are able to survive in extreme environments, including deep-sea vents with temperatures well over 100 degrees Celsius, and highly alkaline, salty, or acidic waters.”

Folder 2: This folder shows how we trace back our lineages to our common ancestor. In the example given, caimans a type of bird, may not seem to be related to crocodiles, a non-flying reptile. The lineages of both those animals are observed to find connections. What every lineage has, is its own distinct history, a...
