Evolution Evolution is change over time. The Theory of Evolution states that all organisms share a single common ancestor and have evolved over time. It also states that this has occurred largely due to changes in environmental conditions that have led to a necessity for organisms to change and adapt or go extinct. Darwin?s Theory of Natural Selection In 1831, Charles Darwin set sail on the HMS Beagle as the ship?s naturalist. His job was to collect biological and geological specimens. After traveling from England across the Atlantic and collecting specimens along the eastern and western coasts of South America, the ship landed in the Galapagos Islands.

Life is made of: The properties of Life: Order Evolutionary adaptation Response to the environment Reproduction Growth & Development Energy processing Regulation EVOLUTION: THE PROCESS OF CHANGE THAT HAS TRANSFORMED LIFE ON EARTH Fossils Prove Evolution Darwin?s Origin of Species (1859) ?Decent with Modification? Descent with modification refers to the passing on of traits from parent organisms to their offspring. This passing on of traits is known as heredity, and the basic unit of heredity is the gene.

CHAPTF,F.24 THE ORIGIN OF SPECIES OUTLII\E L What Is a SPecies? A. The biological species concept emphasizes reproductive isolation B. prezygotic and postzygotic barriers isolate the gene pools of biological species C. The biological species concept does not work in all situations D. Other species concepts emphasize features and processes that identiff and unite species members II. Modes of SPeciation A. Geographical isolation can lead to the origin of species: allopatric speciation B. A new species can originate in the geographical midst of the parent species: sympatric sPeciation c. Genetic change in populations can account for speciation D. The punctuated equilibrium model has stimulated research on the tempo of speciation The Origin of Evolutionary NoveltY

Chapter 22: Descent with Modification: Darwinian View of Life?Lecture Outline Overview: Darwin Introduces a Revolutionary Theory On November 24, 1859, Charles Darwin published On the Origin of Species by Means of Natural Selection. Darwin?s book drew a cohesive picture of life by connecting what had once seemed a bewildering array of unrelated facts. Darwin made two major points in The Origin of Species: Today?s organisms descended from ancestral species that were different from modern species. Natural selection provided a mechanism for this evolutionary change. The basic idea of natural selection is that a population can change over time if individuals that possess certain heritable traits leave more offspring than other individuals.

Selam Kubrom AP World Chapter 1 African Genesis In 1856, Germans discovered bones of a creature with a human body but with the face of an ape (Neanderthals) 3 years later, Charles Darwin in On the Origin of Species that ?the time frame for all biological life was far longer than most persons had supposed.? Natural Selection: The biological process by which variations that enhance a populations ability to survive in a particular environment become dominant in a species over very long periods and lead to evolution of a new species. Africa was thought of the origin of all humans because of the large populations of apes even though there was no evidence.
