PPT-Evolution Is fundamentally, a genetic

process Written in the genetic code of species alive today Story of life on earth is the story of the molecule of lifeDNAand the various ways in which it manifests itself in the form of living species in order to survive. Basic Forces (what is needed for an evolvable system). Evolution – Basic Forces. Self-replication - reproduction. Heritability - a system by which characteristics can be passed from one generation to the next (here on Earth, DNA is that system). . Which one?. There are 3 great universal questions. 1) Where did I come from?. 2) Why am I here?. 3) Where am I going?. The answer to the last 2 questions are dependent upon the answer to the first question. . John Woodward and . Ruibin. . Bai. My interest…. We would not attempt to try to write computer programs without the constructs of. R. eusable. . functions (in GP terminology . ADFs. ),. Iteration. Highlights of what you need to remember:. LEQ: What experiments led to the development of the scientific explanation for the origin of life? . LEQ: How can we use endosymbiosis to support the theory of the origin of eukaryotic cells. . Which one?. There are 3 great universal questions. 1) Where did I come from?. 2) Why am I here?. 3) Where am I going?. The answer to the last 2 questions are dependent upon the answer to the first question. . The Smallest Unit of Evolution. A common misconception is that organisms evolve during their lifetimes. Natural selection acts on individuals, but only populations evolve. Consider, for example, a population of medium ground finches on Daphne Major Island. Chapter Overview Questions. How do scientists account for the development of life on earth?. What is biological evolution by natural selection, and how can it account for the current diversity of organisms on the earth?. 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.. Recent Evolution in Humans. Evolution is very much still happening today — and it's happening to us.. Right here, right now.. Our genes constantly change over time thanks to the power of selection.. 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 . Origins of Life on Earth. 4.7-4.8 Billion Year History. Evidence from chemical analysis and measurements of radioactive elements in primitive rocks and fossils. . Life developed over two main phases:. John Woodward and . Ruibin. . Bai. My interest…. We would not attempt to try to write computer programs without the constructs of.
