<h3>Answer;</h3>

amount of decayed daughter elements

<h3>Explanation;</h3>

Absolute age is the age of a rock in years. Absolute age is found by measuring the amount of certain radioactive elements in the rock.
During the formation of rock, small amounts of radioactive elements is normally included. As the time passes, the parent radioactive elements undergo decay at a regular rate into non-radioactive daughter elements.
By measuring the rate at which a parent element decays and then the ratio of parent element to daughter element in the rock the age of rock in years can be found.

Convergent evolution is the concept of two or more species evolving similar traits despite being completely unrelated to one another, including the absence of a common ancestor.

The Platyrrhines, more commonly known as "New World Monkeys", share many characteristics with the Prosimians. Some of these include:

Teeth layout
Diet
Eyesight
Sleeping habits

and more.

The Platyrrhines and the Prosimians are both nocturnal animals. Despite all other members of their family being active during the day, the Playrrhines have evolved nocturnal habits similar to that of the Prosimians. Aside from that, they feed on insects more so than fruit, which is reflected by the layout of their teeth, and have eyesight well adapted to dark conditions. All of these are traits they share with the Prosimians.

Despite being in different ecosystems and regions, and sharing no recent common ancestors, both of these species have evolved strikingly similar traits. This can be used to corroborate the theory of convergent evolution, which explains how two species can evolve very similar traits despite being unrelated.
