Widgets Human evolution from an ancestral primate species is not a vague hypothesis, but a historical fact.

Archaeological geology as a science had to precede the proposal of evolution, as an understanding of the immense age of the earth is necessary to understand evolution.

Most carbon atoms have six protons and six neutrons in their nuclei and are called carbon 12. But a tiny percentage of carbon is made of carbon 14, or radiocarbon, which has six protons and eight neutrons and is not stable: half of any sample of it decays into other atoms after 5,700 years.

Carbon 14 is continually being created in the Earth's atmosphere by the interaction of nitrogen and gamma rays from outer space.

One known example where this assumption was used is very misleading.

Ice cores showed the age of a military plane buried in the artic as thousands of years old.

Trees undergo spurts in growth in the spring and summer months while becoming somewhat dormant in the fall and winter months.

I have integrated this web page on human evolution into an electronic text, " Nature's Holism - Holism.

Evolution & Ecology " (see its HOME PAGE .) The result is that some areas, such as the glossary are shared.

Some types of relative dating techniques include climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.

Seriation uses the assumption that once a tool was developed, its use would become more widespread.
