![]() Our results reduce the possibility of a strong functional origin for the variation in size and shape of the frontal sinuses in the primates analysed. We suggest that the more vertical orientation of the H. sapiens frontal bone, its reduced thickness, the reduction of the supraorbital tori and the increased influence of the frontal lobes appear to have modified the integration between the skull, brain and sinuses in the frontal region in our species compared to our nearest extant relatives. In H. sapiens, a significant correlation is observed between the asymmetry in the anterior extension of the frontal lobes of the brain and the shape and extension of the frontal sinuses. This suggests that the large space available in the bone structures of the non-human primates analysed allows the sinuses to develop under only slight constraint (if any) from surrounding structures. In P. troglodytes, P. paniscus and G. gorilla, the shape and size of frontal pneumatisation correlates positively with the overall size of the braincase. H. sapiens differs from the other taxa in having relatively smaller frontal sinuses that are more variable in shape and size. However, we also describe differences in frontal pneumatisation between those taxa. We suggest that, in contrast to an allometric relationship between endocranial and frontal sinus form in Pan and Gorilla, H. sapiens is autapomorphic in having highly variable, supero-inferiorly large frontal sinuses, whose size is unrestricted by variation in cranial form. Frontal sinus shape and size are potential phylogenetic markers in primate systematics. ![]() This has allowed the first large study of these variables, including analyses of large samples of P. paniscus, P. troglodytes, G. gorilla and of several geographically diverse populations of H. sapiens. A simple and repeatable method is described here to quantify variation in the shape, size and bilateral variation of the frontal sinuses. Frontal pneumatisation is not present in all primates, and among extant species, ethmoidally-derived frontal sinuses are present only in the genera Pan, Gorilla and Homo. We can now create the CSS that makes this happen. We've preliminarily put some text into our divs to better see how these flex boxes are behaving. Inside this flex box, one of the divs will be an about section, where we'll present information about ourselves, and the other one will contain the actual list of links. We're essentially creating a flex box container that will hold the elements of our page.Ī flex box is a convenient CSS layout model that makes it easy to create responsive behaviour, as it will automtically handle how space is distributed among it's children elements. We can go ahead and already assign class names to each one of them to indicate their function. Not much to see here yet, except for a couple of nested divs in the body tag. ![]() This is some text to be displayed, it's information about you. The only requirement here is basic knowledge of HTML and CSS, the explanations I'll provide! You can basically regard this post as a mini CSS lesson. ![]() Would there be interest if I wrote about how to make a little list like this + hosting it on github pages? /7nDIXc9gnC- Ahmad Moussa || Gorilla Sun April 28, 2023Īlternatively you can also check out the about page of this site to see the final product in action! Let's get started! Here's a video of what we'll make: While we're at it we'll also make it responsive, and get it up and running for free via Github pages. I don't know why it took me so long to try and make my own, but I finally did! And it was easier than expected!ĬSS isn't really that complicated you just need a handful of tricks to make this list happen and make it flashy. Ultimately, you're left with a very bland list of links. Although their analytics did show that I would get some clicks on occasion. ![]() To be frank, I never thought that it was worth the couple of bucks just to get a flashy list of links, so I never did. What always bothered me about it though, was that further styling options were locked behind a paywall. I've used it for a long time myself, since it seemed like the trendy thing to do: having a list of links in your Twitter and Instagram bios to refer folks to the other platforms that you're active on. Everyone and their mom is using Linktree nowadays. ![]()
