Orangutans breed slower than any other primate and have approximately 3 offspring in their lifetime.....Female orangutans usually have one baby at a time and will only have one every 6 to 7 years.....Baby orangutans cry when they’re hungry, whimper when they’re hurt and smile at their mothers.

Orangutans brachiate (swing arm-over-arm through the forest) better than any other ape.....Orangutans are diurnal which means they are active during the day. .....Mosquitoes bother orangutans just like they do humans and they will use branches like fly swatters to swish them away......In their true habitat, male orangutans live alone and females live alone or with their infants.

Am I a primate?


YELLOW

There are some terms that describe the nature of a grouping in such trees. For instance, all birds and reptiles are believed to have descended from a single common ancestor, so this taxonomic grouping is called monophyletic.

CYAN
"Modern reptile" is a grouping that contains a common ancestor, but does not contain all descendants of that ancestor (birds are excluded). This is an example of a paraphyletic group.


RED

A grouping such as warm-blooded animals would include only mammals and birds and is called polyphyletic because the members of this grouping do not include the most recent common ancestor.
