The Genetic Book of the Dead
Richard Dawkins discusses his new book, which explores the concept of the genome as a palimpsest, reflecting the history of life on Earth. He describes how genes act as a record of ancestral environments, where future scientists may eventually read this genetic history to understand evolutionary changes. The book also contrasts genotypes, the genetic makeup, with phenotypes, the observable traits manifesting from those genes. Dawkins illustrates this with the idea that reading a genome could reveal ancient sea-dwelling ancestors of modern mammals, showcasing the rich tapestry of evolutionary history embedded in DNA.
