Can we doubt that individuals having any advantage, however slight, over others, would have the best chance of surviving and of procreating their kind?' In the Origin of Species (1859) Darwin challenged many of the most deeply held beliefs of the Western world. His insistence on the immense length of the past and on the abundance of lifeforms, present and extinct, dislodged man from his central position in creation and called into question the role of the Creator. He showed that new species are achieved by natural selection, and that absence of plan is an inherent part of the evolutionary process. Darwin's prodigious reading, experimentation, and observations on his travels fed into his great work, which draws on material from the Galapagos Islands to rural Staffordshire, from English back gardens to colonial encounters.

The present book is intended, as far as possible, to give an exact insight into the theory of Relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics.

CK12 Foundation's Basic Algebra, Volume 1 FlexBook covers the following six chapters: Expressions, Equations, and Functions  covers the relationships among expressions, equations, and functions when variables are present. Also explored is how these ideas can be shown on graphs. Properties of Real Numbers  covers various forms that rational numbers can assume, including fractions, integers, and square roots. Also considered are different operations for manipulating rational numbers. Linear Equations  introduces students to methods of solving simple equations involving variables. Also covered are ratios, scale, and the percent equation. Graphing Linear Equations and Functions  provides students with a more indepth understanding of equations by introducing coordinate plane graphing concepts such as intercepts and slope. Writing Linear Equations  focuses on writing various forms of equations based upon realworld data and already existing lines. Students will also learn about predicting data using a fitted line. Linear Inequalities and Absolute Value; An Introduction to Probability  covers operations of inequalities, including addition, subtraction, multiplication and division. These principles are then applied to absolute value and probability.
