Mitochondria may even have given rise to sex, which is necessary to maintain the function of genes in large genomes. This high mutation rate lies behind our aging and certain congenital diseases such as cancer. Mitochondria contain genes in their DNA that differ from the genes in the cell nucleus and that mutate much faster than those in the nucleus. The acquisition of mitochondria changed everything, greatly expanding the cell’s genome and volume. When this happened, mitochondria formed from the cell that was captured inside the host cell and continued to live in the new organism. The rare event was an endosymbiosis between two single-cell prokaryotes, forming a eukaryote, a complex cell. ![]() London Life Ascending: The Ten Great Inventions of Evolution, 2009) is known as a writer of popular science, but this is a rigorous work that requires close reading and the ability-and willingness-to tackle and comprehend complex technical processes, such as chemiosmotic coupling and the ATP synthase. An evolutionary biochemist argues that while single-cell life emerged early in Earth’s 4-billion-year history, complex life arose only some 2 billion years ago as the result of a rare, even freakish, event. ![]()
