extinction is a natural process. why are scientists so worried about extinction rates?
u have to creating 2 multiple choice questions, (based on those information). You create 2 multiple choice questions , with a brief description at least 5-9 sentences for each question on why you think they are a corect answer and why you think it is good questions.
-Microevolution: evolution occurring within populations â Adaptive and neutral changes in allele frequencies. -Macroevolution: evolution above the species level â Origination, diversification, and extinction.
-The Motors of Macroevolution: Speciation and Extinction
Speciation and extinction rates produce changing levels of diversity.
Interplay between speciation and extinction determines diversity
D1 (diversity) + originations â extinctions = D2 (new diversity)
