Principles of Evolution

Principles of Evolution

Principles of Evolution. How Did Evolutionary Thought Evolve? Early biological thought did not include the concept of evolution. Exploration of new lands revealed a staggering diversity of life. Fossil discoveries showed that life had changed over Time.

Evolution Lecture 6 : Variation Among Individuals (Chapter 5). Variation. Genetic variation among individuals in populations is obvious (just look around this room!) But we often overlook variation in other organisms (even though it is often greater). Figure 5-1.

Chapter 7: Evolution at multiple loci

Chapter 7: Evolution at multiple loci

Chapter 7: Evolution at multiple loci. Evolution at two loci: Linkage equilibrium and linkage disequilibrium. Locus is location on a chromosome where a gene occurs. Single locus Hardy-Weinberg models are simple. However, many traits are controlled by combined influence of many genes.

Evolution as genetic change 16-2 (Types of Selection)

Evolution as genetic change 16-2 (Types of Selection). Natural selection on single-gene traits can lead to changes in allele frequencies and thus to evolution. Organisms of one color, for example, may produce fewer offspring than organisms of other colors.
