Key Concepts Covered
➡️ Speciation – The process by which populations diverge genetically, eventually becoming separate species
➡️ Reproductive Isolation – Barriers that prevent gene flow between populations, leading to speciation
➡️ Polyploidy – An increase in chromosome number often resulting in new plant species
➡️ Adaptive Radiation – The rapid evolution of diverse species from a common ancestor, typically in response to new ecological niches
➡️ Geographic Barriers – Physical obstacles like mountains or rivers that contribute to population divergence and speciation
