Map of the World by Natural Skin Color
i’m really dumbfounded that i never realized skin colour is literally just caused by being closer to or farther from the equator and the resulting sun exposure and skin darkening
actually, its an adaptation. natural selection. people with darker skin are selected for in areas near the equator, where the melanin that causes the darker color protects them from radiation and protects them from skin cancer and other health defects, and because they are healthier they can pass on that trait more. people near the poles have lighter skin because it allows them absorb more of the limited sunlight to convert to vitamin d.
THIS IS THE THING SOME PEOPLE HATE OTHER PEOPLE OVER.
Evolution of melanin levels based on geographical location.
Reblogging for the last comment.
second to last comment was dope, and very true.
but for real, is the reason behind skin color really not common knowledge? I mean….
there seems to be some assumption going on that darker skin is the adaptation.
in fact, darker skin is the ‘original flavor’. but evolution likes to get rid of traits that aren’t needed, especially if they cost energy, and maintaining a melanin shield is expensive. we also need sunlight to synthesize vitamin D, and melanin blocks that. so in latitudes that get less sunlight, folks evolved to produce less melanin.
vitamin D deficiency is actually a problem for dark-skinned people living in areas with long, dark winters, btw. take your vitamins!
light-colored eyes are also an adaptation to less sunlight. if real life was like science fiction, blue-eyed people could see in the dark. but reality’s not that cool.
Just last week, a 7th grader with a curvy build came home upset about this. She had worn an outfit with a skirt and leggings, and in the morning, a teacher had said to her, “Cute outfit.” But then her homeroom teacher pulled her aside at the end of the day and said, “You know, another girl could get away with that outfit, but you should not be wearing that. I’m going to dress code you.” Juliet Bond and the child’s mom were discussing the incident, not certain if the message to the child was ‘you’re too sexy’ or ‘you’re too fat.’
The kids also report that the teachers have been discussing ‘appropriate body types for leggings and yoga pants and inappropriate body types for yoga pants and leggings.’
Bond says, “This is concerning because it is both slut shaming and fat shaming. If a girl is heavy or developed, the message is that she cannot wear certain clothes.” Neither is acceptable. We should not be sexualizing kids, nor should we be making them feel that they can wear leggings as long as they remain stick thin. Bond asks, “Why are the girls being pulled out of class to have assemblies on whether they are wearing the right clothes, while the boys remain in class, learning and studying?”
I don’t have a problem with a school having a dress code; in fact, I attended a school that didn’t allow jeans or shorts or shirts without collars, but I do have a problem when the dress code is discriminately based on gender and body type. There is a big difference between telling all students to dress respectfully and telling curvy girls to dress in a way that doesn’t distract boys.

Small Pets Are Not Toys
- Never buy an animal on impulse. You are toying with life.
- Store bought cages are very, very rarely large enough for your pet
- Never give a small pet to a child as a gift.
- Never leave a small child alone with a small pet.
- Fish do not belong in fish bowls.
- rabbits do not belong in cages.
- store bought bird cages are too small for any bird larger than a finch.
- chinchillas and rabbits live from 8 to 14 years.
- Some reptiles will only eat live feed. Are you prepared for that?
- Small rodents and rabbits can die of heart attacks when scared. Do you have a quiet home for your new pet?
- adopt when possible.
Honestly, even finches need quite large cages. They’re very active birds and need lots of room to fly in order to stay physically and mentally healthy. They need flight cages.
Oh yeah, other than my breeding pairs in breeding cages (half the height of flight cages) for the sake of their babies not breaking their neck, everyone goes into flight cages, ESPECIALLY the young birds who need to work their muscles and develop strong organs! And when the finches are out of the breeding season its into a large flight cage (and, one day, an aviary that I dream of) for lots of exercise and room to explore. Its essential for their health on all levels!
Commonly known as the “Hairy Yellow Hermit Crab” or the “Large Hairy Hermit Crab” Aniculus maximus is a species of ‘left-handed hermit crab’ (Diogenidae) that is widely distributed throughout the Indo-Pacific. True to its common name Aniculus maximus’ legs are covered with hair-like setae, which may aid in collecting food. Like other hermit crabs Aniculus maximus is an opportunistic omnivore feeding on a wide variety of organisms and organic matter.
Anonymous asked: Shut the fuck up about vaccinations. Not everyone has to have them, not everyone believes in them. Uneducated fuck.
You know, my homie and secret best friend Neil deGrasse Tyson said it best….
This isn’t an issue of belief or should even be up for discussion. It’s not a debate- like gravity or that the Earth revolves around the Sun isn’t up for debate. It’s a fact, whether or not you like it. Sorry bro.
And any ‘educated fuck’ knows that vaccines are necessary and everyone who can have them should have them.
Have a lovely day, sugar.
Actually there’s a lot of research and knowledge supporting the fact that vaccines are NOT necessary. It is simply another thing that today’s health system is super big on, just like hospital births and c-sections. And a lot of people actually have long term and short term complications from getting vaccines. Ahem.
Dang guys, you thought I didn’t check my activity log every now and then? Because I knew shit like this would pop up. And, I just finished my block exam and am feeling fiesty.
Actually you’re wrong. That ‘research’ is either completely fabricated OR grossly misinterprets the data OR uses shitty research techniques to get the data they want- all which are grossly unethical, in case you’re curious. I’ve got slides from a recent lecture on vaccines (aka why I am so fired up about this nonsense). You can check out the citations on each slide if you don’t believe me… something unsurprisingly missing from literally every anti-vaccine comment I’ve gotten and website that I have visited. Show me your sources, honey, and if you do, I will blow them out of the water because not a single one stands up to current scientific research standards.
There are however tomes and tomes of research for the safety end efficacy of vaccines. Don’t believe me? Look at a simple google scholar search.
So! Here we go!
Holy shit, it’s almost like vaccines SAVE SOCIETY MONEY. In fact, they give money back to society, along with the other programs indicated by red arrows. Which would be really weird for something that is just a healthcare fad like c-sections and hospital births.
And most people have no complications for getting vaccines, and if they do, most of them are short term. In fact, it is devilishly hard to prove an adverse effect was because of a vaccine. Why? Because it’s how we’re wired. We falsely see connections and causes where there are none (called a type 1 error; you are rejecting a true null hypothesis). People are more likely to attribute an adverse health event to a shot- even if that shot is the placebo and the numbers are just the background rate for whatever health event in the population.
And here is a graph showing the sample sizes necessary to prove that an adverse event is caused or related to a vaccine.
You know what, it was a really good lecture and I’m going to share more more relevant slides in case any one else feels like contradicting me.
These slides show the public health impact of vaccines. Note the differences between the historical peak and post-vaccine era deaths columns. Because saving literally thousands of lives is totally a conspiracy you should beware of.
And this is why herd immunity is so important! See how high it has to be for measles? Guess what we’re seeing outbreaks of thanks to anti-vaxxers? Don’t forget that one of the deadly complications of measles is SSPE.
Look how Hepatitis A infections in older adults when down after kids started getting immunized. Shocking! Could vaccines be… good for …. everyone????
Anti-vaxxers are a danger to the world and we need to stop them tbh
