) were archaic humans who emerged at least 200,000 years ago and died out perhaps between 35,000 and 24,000 years ago.
They manufactured and used tools (including blades, awls, and sharpening instruments), developed a spoken language, and developed a rich culture that involved hearth construction, traditional medicine, and the burial of their dead.
After World War II, geologists developed the paleomagnetic dating technique to measure the movements of the magnetic north pole over geologic time. Robert Dubois introduced this new absolute dating technique to archaeology as archaeomagnetic dating.
Magnetism occurs whenever electrically charged particles are in motion.
Particular attention is paid to the fossil evidence for this history and to the principal models of evolution that have gained the most credence in the scientific community.
the article evolution for a full explanation of evolutionary theory, including its main proponents both before and after Darwin, its arousal of both resistance and acceptance in society, and the scientific tools used to investigate the theory and prove its validity.
The Earth's magnetic north pole can change in orientation (from north to south and south to north), and has many times over the millions of years that this planet has existed.
The term that refers to changes in the Earth's magnetic field in the past is paleomagnetism.
The Earth's molten core has electric currents flowing through it.
