Cladistics: This is a method of classifying living organisms based on the most recent common ancestors. It's like organizing a family reunion based on who shares which grandparents.
Homologous Structures:These are structures in different species that have similar form or function due to shared ancestry. Like how you and your cousin might both have grandma’s nose!
Convergent Evolution:This occurs when unrelated organisms independently evolve similar traits as they adapt to similar environments. It's like two unrelated people both becoming chefs because they live in food-loving cities.
