Summarize the following:
Human brains are large relative to the size of our heads, so our skulls generally look bulbous next to the face. Alternatively, animal skulls tend to be more curved, since they house a smaller brain. Animal skulls will have larger faces in comparison to the skull. If you find a skull you're not sure about, call the police. Most animals do not have a chin. When you're examining a skull, look closely to see if it has a chin extending from the front of the skull at the bottom. If it does, it's likely human. If not, it's likely an animal. Humans have the orbits (eye sockets) to the front, above the nose. On the other hand, animals' orbits are to the side and behind the nose. You should be able to distinguish this feature on a skull by examining how the eye sockets are situated in the skull. Also, check for how far the nose and face extend outward. In animals, the nasal area extends much farther out than in humans. Look for the hole at the base of the skull. This hole is called the foreman magnum, and it's how the spinal column connects to the brain. Because humans stand upright, the hole is more centrally located underneath the skull. In other mammals, the hole is further back, since they typically hold their bodies more parallel to the ground. Think about how humans walk versus how a dog or even a gorilla walks for instance. The human head extends straight upward from the shoulder, while a dog or gorilla head comes up at an angle. If you think about where the connection point would be, you'll be able to establish where the hole should be on each animal. The canines are the pointy, fang-like teeth. Since humans are omnivores, the canines will be present like other meat-eaters. However, human canines tend to be smaller than those of most predators/carnivores, which have long, cone-shaped canines. Herbivores, animals that eat only vegetation, will have very small canines or none at all. Also, with the exception of horses, humans have larger incisors than other mammals. The incisors are the straight-edged teeth at the very front of the mouth.

summary: Look for a relatively large, bulbous skull in humans. Check for a chin to identify a human skull. Look for eyes above the nose in humans. See if the skull would sit above or in front of the spinal column. Check for small canines in the mouth for humans.

You can find "Photos" in the Apps section of the menu. Make sure you're using the desktop version of the website. It is not possible to upload videos from the Facebook mobile website. If you're on a mobile device and want to upload a video to Facebook, you'll need to use the mobile app. This will open the video uploader. A file browser will open and you can find the video file you want to upload from your computer. Facebook accepts virtually all common video formats, including mp4, mov, mkv, avi, and wmv. Length is limited to 120 minutes and file size is limited to 4 GB. You can add this information using the fields below the file. These fields are optional, but can help other users find and understand your video. Click the drop-down menu next to the "Post" button to select who can view the video. If you only want the video to be viewable by you, select "Only Me." It will still be posted to your timeline, but only you will be able to see it. After uploading, your video will be viewable by the audience you selected. All videos that you upload to Facebook are posted to the News Feed. There is no way to upload a video without "posting" it, even if the audience is just set to yourself. Long videos will take a while to upload and even longer to process. Make sure you have a strong connection before uploading large video files. You can find all of your uploaded videos by opening the "Photos" app from the menu on the left. Click the "Albums" tab and then select the "Videos" album to see all of your uploaded videos.
summary: Click the "Photos" option in the menu on the left. Click the "Add Video" button. Browse for the video file by clicking "Choose File." Add a title, description, and location. Select your audience. Click "Post" and wait for your video to upload. Find your video in the Photos section of Facebook.
