Animal and plant cell DNA is so complicated that all the cellular machines that process, regulate, and manipulate it are constantly in need of cellular fuel. In fact, each animal and plant cell uses so much fuel that specialized fuel-production facilities called mitochondria are required.

Where did the first living cell come from? According to The Independent, Charles Darwin "was flummoxed by the ultimate mystery of mysteries: what led to the origin of life itself?"¹

The evolutionary age assignment for mankind just doubled, according to new research. Teeth were discovered in an Israeli cave in a context of unprecedented age for human remains. This evidence refutes long-held ideas about human evolution, including the "out of Africa" story and the whole presumed timing of human development.

In 2009, Brown University biology professor Ken Miller wrote in the journal New Scientist that "the most profound unsolved problem in biology is the origin of life itself."¹

Philosopher and secular humanist Christopher diCarlo claims that if humans trace their lineages far enough back in time, they will all have an African origin. He has been spreading his "We Are All African!"¹ message on a cross-Canadian tour. However, the science behind diCarlo's version of history leaves plenty of room for skepticism.
