Perhaps we should take this opportunity to review some of the basic science behind the study of C plants as they relate to human evolution. With its four valence electrons, Carbon (C) is quite suited to act as the backbone in the molecules that are the foundation of life as we know it (proteins, the nucleic acids of DNA, lipids, etc.).Carbon exists naturally in three forms (or isotopes).(Only a handful of nuclides with atomic numbers less than 83 emit an -particle.) The product of -decay is easy to predict if we assume that both mass and charge are conserved in nuclear reactions.Alpha decay of the The sum of the mass numbers of the products (234 4) is equal to the mass number of the parent nuclide (238), and the sum of the charges on the products (90 2) is equal to the charge on the parent nuclide.As research on early hominin diets progresses, using stable isotope analysis as well as dental microwear analysis, we are finding that perhaps our early ancestors consumed more C plants than earlier thought.So, this begs the question, what exactly did they eat?
Typically the number of neutral neutrons in the nucleus is equal to the number of protons.
Oliver Paine’s project will help us begin to answer these and many more questions.

However, this ratio does give us information on where these animals derived their food.
As we have now learned, these C plants grow in dissimilar environments.
These types of plants are usually restricted to desert environments.
