Summary of Carl Sagan's The Dragons of Eden

By IRB Media

Please note: This is a companion version & not the original book.

#1 The universe is very old, and human beings are very young. Events in our personal lives are measured in years or less, while our lifetimes are measured in decades. The chronology corresponds to the best evidence available. But some of it is rather shaky.

#2 The first cosmic year is measured in seconds, and it is clear that what happens on and near Earth at the beginning of the second cosmic year will depend on the scientific wisdom and human sensitivity of mankind.

Insights from Chapter 2

#1

The largest taxonomic divisions distinguish between plants and animals, or between those organisms with poorly developed nuclei in their cells and those with very clearly demarcated and elaborately architectured nuclei. All organisms on the planet Earth have chromosomes, which contain the genetic material passed on from generation to generation.

#2

The genetic code is written in a language of four letters, and the information content of a DNA molecule is four times the number of nucleotide pairs. The book of life is very rich, and the genetic instructions of all the other taxa on Earth are written in the same language.
