Here you need to put if you have any questions about the material you are learning. If you have none i would consider putting that you have none.
When light traveling in a vacuum enters a new transparent medium, such as air, water, or glass, the speed is reduced in proportion to the refractive index of the new material. As the slider is translated to the right, the refractive index increases and the speed of light subsequently decreases.

During 66 mya in the Paleocene scientists believe the first primates may have evolved.
<h3>
Evolution of Primates</h3>
- Most likely, a small, nocturnal, insectivorous animal that gave rise to the first primates. The closest extant cousins of primates are tree shrews and colugos, also referred to as flying lemurs.
- The tree shrew is cited as a living example of what the ancestors of primates, or the earliest primates, would have looked like.
- The most ancient ape discovered by reliable fossil evidence is Dryomomys. Only isolated teeth and jaw fragments from Purgatorius, the earliest known primate, which dates back 65 million years, are known.
- In the primate suborder Strepsirhini, the Eocene primates split into two groups at an early stage: the omomyids and the adapids, collectively known as the prosimians.
