Overview

This short slide set relates the role of RNA in the processes of transcription and translation to RNA's evolutionary history and the remnants of the RNA world. Save the slide set to your computer to view the explanation and notes that go along with each slide.

  • [History of life: Grades 13-16] Life forms of the past were in some ways very different from living forms of today, but in other ways very similar.
  • [Evidence of evolution: Grades 13-16] An organism's features reflect its evolutionary history.
  • [Evidence of evolution: Grades 13-16] Similarities among existing organisms (including morphological, developmental, and molecular similarities) reflect common ancestry and provide evidence for evolution.
  • [Mechanisms of evolution: Grades 13-16] Evolution results from mutations.
  • [Mechanisms of evolution: Grades 13-16] Natural selection and genetic drift act on the variation that exists in a population.
  • [Mechanisms of evolution: Grades 13-16] Over time, the proportion of individuals with advantageous traits may increase (and the proportion with disadvantageous traits may decrease) due to their chances of surviving and reproducing.
  • [Mechanisms of evolution: Grades 13-16] Natural selection is capable of acting at multiple hierarchical levels: on genes, on cells, on individuals, on populations, on species, and on larger clades.
