The gene for the human hormone insulin can be inserted into bacteria, and the resulting bacteria can use the gene to produce functional insulin. A robin can fly, but a penguin cannot.

- The video game “Spore” invites players to design creatures and guidethem through “five stages of evolution.” Search the Internet forinformation about “Spore”; describe how evolution in this game issimilar to, and different from, the evolution of life on Earth.WRITE ABOUT A THEME: Organization You have seenmany examples of how form fits function at all levels of thebiological hierarchy. However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.Based on genes from mitochordrial DNA the most accepted tree of life includes three domains. Eukaryotes and archaea are most closely related to each other than either are to bacteria. MRNA rRNA TRNA 0000
