Question

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 –
Adaptive and neutral changes in allele frequencies.
-Macroevolution: evolution above the species level –
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 – extinctions = D2 (new diversity)

Explanation / Answer

1. Within the adaptive zone in macroevolution each group of the animal occupies a narrow adaptive field called

a. Unstable zone

b. Sub zone

c. Stable zone

Ans. Sub zone

A genera, a family or an order is formed of group of animals that have a characteristic similarity in their way of life. They share a common adaptive zone. Within the zone each group of the animal occupies a narrow adaptive field called sub zone. Thus a major adaptive zone has many sub zones.

2. The term macroevolution was coined

a. Goldschmidt

b. Cabrera

c. Simpson

Ans. Goldschmidt

Macroevolution is brought about by large, sudden, rapid mutations. He termed these mutations as macromutations or systemic mutations.
