Question

question 8 (mandatory) (2 points)
the disappearance of dinosaurs is an example of ______________.
sympatric speciation
hybrid inviability
macroevolution
adaptive release

Explanation:

• Sympatric speciation refers to the formation of new species within a single population without geographical isolation. Dinosaurs' disappearance is not about speciation in this sense.
• Hybrid inviability is a post - zygotic reproductive barrier where hybrid offspring are not viable. This is not related to the disappearance of dinosaurs.
• Macroevolution involves large - scale evolutionary changes over long periods, such as the extinction of entire groups (like dinosaurs).
• Adaptive release is about a species expanding its ecological niche. Dinosaurs' disappearance is not an example of this.

Answer:

C. Macroevolution
