Practice Speciation and extinction with authentic MYP MYP Biology exam questions for both SL and HL students. This question bank mirrors Paper 1, 2, 3 structure, covering key topics like cell biology, genetics, and ecology. Get instant solutions, detailed explanations, and build exam confidence with questions in the style of MYP examiners.
Which process is defined specifically as the event where one original species splits into two or more distinct species?
What is the primary mechanism that ensures the gene pools of two distinct species remain separate even if they occupy the same territory?
True or False: The incomplete nature of the fossil record is considered a significant piece of evidence that weakens the validity of evolutionary theory.
Which mechanism acts as a post-zygotic barrier in sympatric speciation by preventing the mixing of gene pools even if mating between two different groups occurs?
Which factor provides the raw genetic variation necessary for populations to diverge over many generations during the process of speciation?
For speciation to occur, a lack of __________ is necessary to prevent alleles from mixing between separating populations.
As isolated populations accumulate different genetic mutations and experience unique selection pressures over time, what is the ultimate result?
In a ring species, what prevents the two terminal populations from successfully interbreeding if they come into contact?
What mechanism allows adjacent populations in a ring species to remain genetically similar enough to interbreed?
In a ring species, the presence of a __________ of traits across adjacent populations demonstrates that reproductive isolation can develop incrementally across a landscape.
