Regardless of the careers that they ultimately select, to succeed in today's scientifically and technologically sophisticated world, all students need a sound education in science. Many of today's fast-growing and high-paying jobs require a familiarity with the core concepts, applications, and implications of science. To make informed decisions about public policies, people need to know how scientific evidence supports those policies and whether that evidence was gathered using well-established scientific practice and principles. Learning about evolution is an excellent way to help students understand the nature, processes, and limits of science in addition to concepts about this fundamentally important contribution to scientific knowledge.
The laws of motion explain that matter stays in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed upon it. Thus, patterns produced by material causes reflect an intersection of forces which start or stop the motion of matter. An intervening warm spell that melted a glacier carrying rocks and boulders caused them to come to rest in an unsorted pattern as glacial till. Similarly, when the Mississippi River hits the Gulf of Mexico it drops a load that forms a fan-shaped delta.
