Origins of Life

Lecture Notes: #content

Summarize hypotheses of early life

Miller & Urey - chemical and electric atmosphere (constructed a lab apparatus, but probably not totally accurate)

Hydrothermal origins - areas of volcanic activity and chemically rich water --> archaebacteria

Meteorite hypothesis - seeds of life from outer space (evidence of organic molecules in meteorites and from analysis of other planets)

Liposome hypotheses - lipid particles formed membranes which separated nucleic acids and proteins from environment

The 3 Domain/6 Kingdom systems

Origins of Life -Spontaneous generation & Biogenesis - <summarize Redi, Spallanzani and Pasteur's basic experiments (SOL1) that showed that life can not appear spontaneously>

Extension Activity: “In the Beginning…” - read the Economist article and submit answers

  1. Two important papers were published in 1953. What were the titles and authors of these articles?

  2. Describe the experiment and results that simulated Darwin’s “warm little pond.”

  3. What three questions do we still have about the origin of life?

  4. Summarize each of the “above, below, or beyond” of Dr. Bernstein and Dr. Thaddeus.

  5. The third to last paragraph ends with the question “How, then, did life survive the constant rain of asteroids?” Summarize Dr. Cockell’s findings.
