LF263-15 Evolution
Introductory description
Evolution and genetics are the two great unifying themes in biology. At one level evolution can be defined as the changes in gene frequencies in populations with time. An understanding of population genetics and evolutionary genetics is necessary to understand fundamental processes of evolutionary change, and importantly, is necessary to understand the genetic make-up of existing populations observed and studied in real time. This theoretical background is also necessary to understand the use of DNA sequence data and related information in deducing evolutionary relationships.
Module aims
An understanding of population genetics and evolutionary genetics is necessary to understand fundamental processes of evolutionary change and is necessary to understand the genetic make-up of existing populations observed and studied in real-time. This is natural core material for Biological Science students.
i) The enduring influence Darwinian thought has on modern evolutionary theory.
(ii) The 'Modern Synthesis' of Darwinism and genetics.
(iii) Mechanistic aspects of fundamental evolutionary and population genetic processes at a simple level.
(iv) The definition of, and distinction between, the different kinds of genetic polymorphism observed in populations, and how polymorphism is maintained.
(v) The consequences of molecular evolutionary theory, including the molecular clock concept, and the use of molecular evolutionary theory for phenetic comparisons and cladistic deductions.
(vi) Different mechanisms of speciation.
(vii) How macro-evolution can be studied through comparative developmental biology and paleontology.
(viii) How evolution is studied at the genome level in the wake of new technologies.
