This Biology 376 Glossary was begun in Fall 1995 by the Biology 212 class at Lafayette College, and continued to be developed each semester by the instructor and students each year. Hypotheses regarding how speciation begins differ in the role of geographic isolation and the origin of reproductive isolation (preventing populations from breeding with one another). noun. a particular item, … (Yep, that includes IB Biology SL/HL exams, too.) the act of specifying. Aspects of human biology are diverse and may interest anyone who wants to learn more about how the body works or wants a career in scientific research or healthcare. Defining speciation.
Due to genetic isolation, the differences in gene pool among species become so great that they cannot reproduce through interbreeding. noun, plural: speciations.
Speciation is a lineage-splitting event that produces two or more separate species. IB Biology SL and HL Core.
