When an animal dies, it stops taking in new carbon.

The carbon-14 it contains, though, continues to decay, while the amount of normal carbon-12 remains the same.

Modern humans evolved within the last 600,000 years, our own species within the last 200,000 years. Differences in populations in skin color reflect adaptation to different environments, rather than genetic differentiation among populations.

Our species appears to have evolved in Africa, and then migrated to Europe and Asia. Imagine that in 2017 our children are being taught such inaccurate information!

The Neanderthals appear to have walked in a more irregular, side-to-side fashion than do modern humans.

Neanderthals were the first human group to survive in northern latitudes during the cold (glacial) phases of the Pleistocene.

Scientists have measured the half-life of carbon-14 atoms to be approximately 5,700 years.

At the same time, the environment constantly produces new carbon-14, so that the percentage of carbon-14 in all living plants and animals remains fairly constant.

Cranial capacity equaled or surpassed that of modern humans, though their braincases were long, low, and wide and flattened behind.Other radioactive isotopes, such as potassium-40, uranium-235, uranium-238, thorium-232, and rubidium-87, have half-lives that extend from millions to billions of years.To date - relatively FEW skeletons of ancient “HOMOs” have been found.But we are not after Mc Graw-Hill Education specifically; rather we are after the Anthropologists who teach such nonsense.

Firstly – We ARE the only “Modern Humans”: Cro-Magnon and Neanderthal are NOT modern Humans.

They wore clothing, used fire, hunted small and medium-sized animals (like goats and small deer), and they scavenged from the kills of large carnivores.
