Summary of Nicholas Wade's Before the Dawn

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

#1 The human genome, which is the repository of hereditary information that is in constant flux, can be interrogated at many different time levels. It can supply answers that reach back more than 50,000 years to the genetic Adam, a man whose Y chromosome is carried by all men now alive.

#2 The book describes the aspects of human evolution that have been illuminated by genetic discoveries. It explains how humans evolved from apes, and it details the events that occurred after humans left Africa.

#3 The date that people first sewed their own clothes was found in 1999 by geneticists. They had collected head and body lice from 12 countries around the world, and analyzed the variations in a small segment of each louse’s genetic material. They then arranged the lice in a family tree.

#4 The branch point at which the body louse first evolved from the head louse was around 72,000 years ago. Assuming that the body louse evolved almost immediately after its new niche was available to it, people first addressed their nakedness only a few thousand years ago.

#1

The human genome, which is the repository of hereditary information that is in constant flux, can be interrogated at many different time levels. It can supply answers that reach back more than 50,000 years to the genetic Adam, a man whose Y chromosome is carried by all men now alive.

The book describes the aspects of human evolution that have been illuminated by genetic discoveries. It explains how humans evolved from apes, and it details the events that occurred after humans left Africa.

The date that people first sewed their own clothes was found in 1999 by geneticists. They had collected head and body lice from 12 countries around the world, and analyzed the variations in a small segment of each louse’s genetic material. They then arranged the lice in a family tree.

#4

The branch point at which the body louse first evolved from the head louse was around 72,000 years ago. Assuming that the body louse evolved almost immediately after its new niche was available to it, people first addressed their nakedness only a few thousand years ago.

#5

The human genome is a new source of data that enriches all the disciplines concerned with the human past. It furnishes two types of information: genes and genealogies.

#6

The human genome records a vast span of the human past, and enriches the findings of traditional disciplines. It has added new insights into the following themes: there is a clear continuity between the ape world and the human world, and human society has been the most significant force in shaping human evolution.

#7

The first behaviorally modern humans were able to leave Africa and displace the archaic humans like the Neanderthals who had left Africa many thousands of years earlier. The first modern humans to leave Africa probably crossed over the Red Sea at its southern end and into Arabia.

#8

The human genome contains excellent records of the recent past, which can be used to reconstruct the genealogy of human languages. The genome evolves so fast that it retains the secret family history of individuals such as Thomas Jefferson.

#9

The book of Genesis did its best to explain human origins, but modern discoveries have filled in the gaps. The biological framework of human origins is beginning to emerge as the record of past evolutionary change streams forth from the human genome.

Insights from Chapter 2

#1

The group that left Africa 50,000 years ago was able to succeed where all previous emigrants had failed because they were able to develop a critical component of human society: social intelligence.

#2

The chimp-human divergence is estimated to
