It is impossible to give an evolutionary sequence to the human fossils because there is a coverage gap involving the dating methods which evolutionists believe are the most reliable radiocarbon and potassium argon. This gap is from about 40,000 (years ago) to about 200,000 ya on the evolutionist's time scale. It covers roughly the period known as the Middle Stone Age (MSA). This coverage gap lies beyond what is considered the effective range for radiocarbon and prior to what is considered the effective range for potassium argon. This problem period may be even larger because: (1) some dating authorities believe that the effective range for K-Ar doesn't begin until about 400,000 ya, and (2) many of the older fossils are found at sites that lack the volcanic rocks necessary for K-Ar dating and hence cannot be dated by this method at all.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
