Synopsis

Are inherited changes the engine of evolution? This book argues they are, and explains how genetic variations shape life's course.

It frames evolution around five key features—transform, diversify, adapt, progress, and continue—then shows how variations must be inherited to impact future generations. The text delves into the biology of genes, germ plasm, and how chromosomes carry information that shapes the development and traits of organisms. It also discusses how environmental factors can induce lasting changes in genetic material, sometimes through complex chromosome changes.

• Defines what counts as a genetic variation and why inheritance matters for evolution
• Describes germ plasm, genes, and the role of the nucleus in heredity
• Explores how chromosome breaks, inversions, deletions, and translocations relate to mutations
• Links environmental conditions to inherited changes across generations

Ideal for readers of scientific inquiry into evolution and heredity, curious about how genetic variation connects to the history of life.
