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.

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.

CAMPBELL BIOLOGY, AP* 9th EDITION Chapter 26: Phylogeny and the Tree of Life Biologists trace phylogeny - evolutionary history of a species or group of species To construct phylogenies, biologists use systematics - a discipline focused on classifying organisms and determining their evolutionary relationships. 26.1 The scientific discipline of taxonomy is how organisms are named and classified Common names don?t necessarily reflect the organism they signify (ex: silverfish is a bug and jellyfish is a cnidarian). So, we use Latin scientific names. They come in binomial, or two-part, format. Part 1 - the genus (pl. genera) of the organism Part 2 - ?specific epithet?, which is unique for every species in the genus.

STUDY GUIDE: CH. 13 MEIOSIS AND SEXUAL LIFE CYCLE AN INTRODUCTION TO HEREDITY 1. Explain why organisms reproduce only their own kind and why offspring more closely resemble their parents than unrelated individuals of the same species. -We pass coded information in the form of DNA to our offspring -DNA can change in increments -Within species there may be significant variation -The more distantly related, the more different 2. Explain what makes heredity possible. -DNA is copied and then passed -Inheritance is an orderly, quantitative process -Most often, matched sets of genes are inherited from two parents 3. Distinguish asexual and sexual reproduction. -Asexual- one parent, offspring=clone, DNA passed was grouped by mitosis, faster, simpler, less energy,

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.
