PPT-Chapter 12: Processes of Evolution

Part 2 Condition 5 No Natural Selection Balanced polymorphism occurs when natural selection favors heterozygous individuals in a population Heterozygotes are selected for by the environment.

Section 1: The Theory of Evolution by Natural Selection. Darwin Proposed a Mechanism for Evolution. In 1859, the English naturalist Charles Darwin published convincing evidence that species evolve, and he proposed a reasonable mechanism explaining how evolution occurs.. 1. Topics covered. Evolution processes. Legacy systems. Software maintenance. 2. Software change. Software change is inevitable. New requirements emerge when the software is used;. The business environment changes;. Lecture 1. 1. Chapter 9 Software evolution. Topics covered. Evolution processes. Change processes for software systems . Program evolution dynamics. Understanding software evolution. Software maintenance. History of Evolution. The evolution of life is linked to the physical and chemical evolution of the earth.. Life on earth evolved in two phases over the past 4.7 -4.8 billion years. Chemical evolution (1 billion years) of the organic molecules and systems of chemical reactions needed to form the first proto-cells.. Early scientists proposed ideas about evolution. . Evolution is the biological change process by which descendants come to differ from their ancestors.. A species is a group of organisms that can reproduce and have fertile offspring.. Module 14 . The . Biodiversity of Earth. After reading this module you should be able to. understand . how we estimate the number of species living on Earth.. quantify . biodiversity.. describe . patterns of relatedness among species using a . Chapter 17: Processes of Evolution. Early Beliefs. 19. th. century: discovered species shared many traits, but lived in different parts of the world. Problematic – species only looked similar on the outside, but inside were very different .
