This short slide set explains how some antibiotics target the bacterial ribosome and don't attack the ribosomes in our own cells through a quirk of evolutionary history. Save the slide set to your computer to view the explanation and notes that go along with each slide.

Use this resource to relate evolutionary concepts to the topics of organelle structure or transcription/translation (or get more suggestions for incorporating evolution throughout your biology syllabus). Incorporate these slides immediately after youíve discussed the ribosome--either as a cellular structure or its role in protein synthesis.
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- Through billions of years of evolution, life forms have continued to diversify in a branching pattern, from single-celled ancestors to the diversity of life on Earth today.
- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
- The early evolutionary process of eukaryotes included the merging of prokaryote cells.
- An organismís features reflect its evolutionary history.
