Answer: a. Adaptive radiation of Euprimates.
Explanation:
Adaptive radiation is the swift diversification, from a single common ancestor, of a group of species consisting of members that exhibit a diverse array of adaptations and inhabit different ecological niches.
Climate is an important factor that determines where a species can inhabit or not. Daily and seasonal variations in temperature, annual cycles of precipitation, and larger change in climate shape adaptations of plants and animals may be considered in determining their survival. Changes in global and regional climates seemingly had profound effects on the evolutionary history and adaptive radiation of Euprimates.
A rapid temperature increase about 55 mya created tropical conditions globally that caused the adaptive radiation of Euprimates. Warm climates during the Eocene that resulted in plant diversity, created new environmental niches favorable for primates leading to the record of first major primate group: anthropoids, adapiforms, tarsiers, and omomyiforms.
If the ulnar nerve is damaged, it could result to the following:
-
a condition known as “claw hand”
- the inability to adduct or abduct the fingers "ape hand"
- a diminished ability to oppose the thumb toward the little finger
In simple terms, damage to the ulnar nerve results in the inability to flex the wrist.
Organisms are classified into three Domains and into one of six Kingdoms of life. These Kingdoms are Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia.
