Analogy of the Big Bang theory to biological evolution.
Many insights can be gained from the comparison:
1. Evolution begins with a primordial soup; the Big Bang begins with a particle soup.
2. Evolution has missing links; the Big Bang has missing mass.
3. Evolution has no explanation for the origin of life; the Big Bang has no explanation for the origin of matter.
4. In evolution, life started abruptly; in the Big Bang, the universe came into being abruptly.
5. Evolution has asymmetry in proteins; the Big Bang has asymmetry in antimatter.
6. Evolution has an uncomfortably early appearance of the first life; the Big Bang has an uncomfortably early appearance of stars and galaxies.
7. Evolution has a Cambrian explosion; the Big Bang has a structure explosion.
8. Evolution has punctuated equilibria; the Big Bang has quantized redshifts.
9. Evolution has out-of-order fossils; the Big Bang has out-of-order stars, and clusters “older” than the universe.
