Why do people fall under order primates?
Primates (including humans) are different to all other animals because they are the only mammals that have the following combination of features: relatively large, complex brain. forward-facing eyes with overlapping fields of view that allow depth perception.
What are the similarities and differences of primates?
Living Primates Because primates are related, they are genetically similar. Human DNA is, on average, 96% identical to the DNA of our most distant primate relatives, and nearly 99% identical to our closest relatives, chimpanzees and bonobos.
Do our similarities with chimpanzees mean we came from them?
Human and chimp DNA is so similar because the two species are so closely related. Humans, chimps and bonobos descended from a single ancestor species that lived six or seven million years ago. As humans and chimps gradually evolved from a common ancestor, their DNA, passed from generation to generation, changed too.

What is the difference between a dry and semi dry snorkel?
Semi-dry and dry snorkels have been a source of intrigue for many beginners and aspiring divers. Semi-dry snorkels are designed to keep water out by using a splash guard at the top of the tube. On the other hand, a dry snorkel is characterized by a specialized valve mechanism on top of the tube.
Can you breathe with a snorkel underwater?
Breathing underwater along the surface of the water is possible with a snorkel. The snorkel is a tube that attaches to your mouth and loops around past your face, pointing upwards to the surface. The snorkel sticks out of the water and provides you access to fresh air.
Do I need a dry snorkel?
Dry Valve at Top of Tube Poorly designed ones don’t work well, and often get stuck in a closed position even when not underwater, making it so you can’t breathe, and forcing you to have to pull the snorkel out of your mouth. Generally for people who only snorkel on the surface we recommend a good dry snorkel.
