He wants to protect himself
Answer:
The answer is below
Explanation:
The significance of having three branches of government is tremendous and can't be overemphasized. Some of the significance includes:
1. It makes the government effective and efficient.
2. Having three branches of government protects the rights of the citizens
3. It prevents arbitrary use of power by the government
Are there advantages if the responsibility to govern is shouldered only by one branch?
No there are no advantages. If any branch of government turned has all the power of the executive, judiciary, and legislative there will eventually be an arbitrary use of power in the long run, and this will affect the citizens and that society at large. This has been proven in human history in the past in the case of the dictator and absolute monarchy.
Earliest human migrations and expansions of archaic and modern humans across continents began 2 million years ago with the migration out of Africa of Homo erectus. This was followed by the migrations of other pre-modern humans including H. heidelbergensis, the likely ancestor of both modern humans and Neanderthals. Finally, Homo sapiens ventured out of Africa around 100,000 years ago, spread across Asia around 60,000 years ago and arrived on new continents and islands since then.
Knowledge of early human migrations, a major topic of archeology, has been achieved by the study of human fossils, occasionally by stone-age artifacts and more recently has been assisted by archaeogenetics. Cultural and ethnic migrations are estimated by combining archaeogenetics and comparative linguistics.
