This course is designed to scientifically study the kinds and diversity of organisms (populations, species and higher taxa) and the relationship among organisms with their common ancestors.  It includes determination of organisms by means of morphological, biochemical and molecular comparisons and resemblances. The ultimate objective of this course is to understand the biological causes of the difference or shared characteristics and study of variation within taxa. Students in this course will also understand the role of this course in relation to other fields.
