Overview
This news brief from November 2009 focuses on how changes in atmospheric chemistry may have factored into the evolution of life on Earth, specifically, life's quadrillion-fold growth spurt from microscopic bacteria to organisms the size of the blue whale.
- [History of life: Grades 9-12] Living things have had a major influence on the composition of the atmosphere and on the surface of the planet. (ESS2.E)
- [History of life: Grades 9-12] Rates of evolution vary.
- [History of life: Grades 13-16] Biological evolution accounts for diversity over long periods of time.
- [History of life: Grades 13-16] Geological change and biological evolution are linked.
- [Evidence of evolution: Grades 9-12] The fossil record documents the biodiversity of the past.
- [Evidence of evolution: Grades 13-16] The patterns of life's diversity through time provide evidence of evolution.
- [Evidence of evolution: Grades 13-16] The fossil record provides evidence for evolution.
- [Mechanisms of evolution: Grades 9-12] Environmental changes may provide opportunities that can influence natural selection. (LS4.B, LS4.C)
- [Nature of science: Grades 9-12] Scientists test their ideas using multiple lines of evidence. (P6, NOS2)
- [Nature of science: Grades 9-12] Scientists use multiple research methods (experiments, observational research, comparative research, and modeling) to collect data. (P2, P3, P4, NOS1)
- [Nature of science: Grades 9-12] Scientists can test ideas about events and processes long past, very distant, and not directly observable.
- [Nature of science: Grades 13-16] A hallmark of science is exposing ideas to testing.
- [Studying evolution: Grades 9-12] Scientists use fossils (including sequences of fossils showing gradual change over time) to learn about past life.
- [Studying evolution: Grades 13-16] Our knowledge of the evolution of living things is always being refined as we gather more evidence.
- [Studying evolution: Grades 13-16] Our understanding of life through time is based upon multiple lines of evidence.
