Flashcards in Chapter 21 Deck (8):
Why do ecologists think that historical and evolutionary effects better explain the characteristics of mammal species in Australia than environmental effects?
When studying global patterns of diversity, why is it important to understand continental drift?
What is the relationship between the length of time the modern continents have been connected and the similarity among the species on each continent?
How does knowledge of historic climatic patterns affect our interpretation of present-day patterns of species diversity?
What does the observation of convergent traits among distantly related species tell us about evolution by natural selection?
Why does initial trait similarity between closely related species often favor the evolution of trait divergence?
In what way do the age and area of a region affect its species richness?
