Beyond the architecture of our body, it is the beauty of the soul that defines us, that unfading beauty, allows us to shine and shine ...The vision we have of that inner beauty is what others will see as well.

i learned that dire wolves are not wolves at all. They are a seperate lineage of canines that split from wolves six million years ago (x)

Anurognathus Poster

Anurognathus was an adorable wittle-bitty frog-faced pterosaur from the late Jurassic Period. Its big, cute eyes helped it see in low-light conditions and its robust wings made it an acrobatic predator.

If you don't take accountability for your behavior. I will cut you off in a heartbeat. I don't want friends who lead with a victim mentality constantly.

I've recently removed toxic energy from my life and it feels absolutely amazing. Taking accountability for your own toxic energy when another calls you out and further taking it as a lesson for growth is healthy as fuck. Accountability and awareness is immensely important in friendships 🤞🏼

The context:  Crabs and crab-like body plans have evolved independently (convergently) at least 5 times in earth's history.  This is called carcinisation.

Don't be a "maybe". It's either Hell Yes or Fucking No.

how to organisms know what to mimic? like butterflies can have the pattern of eyes on them to deter predators but how did they even get that in the first place? is it like a vague eye-like pattern showed up one day and those had better survival rates causing it to be prominent through natural selection?

they don’t! there’s no actual brains behind the operation per se, simple patterns gradually evolve into more complex ones over time, like you say, due to what we call selection pressure! 

so say that you have a field of plain yellow butterflies. 

ordinary, completely boring, nothing special about them. 

we’re going to expect that all of these yellow butterflies will have a roughly equal chance of being captured and devoured alive by birds, with some corrective leeway for avian mishaps and dumb luck!

and lets say this continues for 100 butterfly generations, spanning a century of realtime. in that span, a random mutation occurs that gives one of the butterflies patches of additional melanin on its wings, resulting in small spots!

a very slight difference, sure, but birds are sensitive to environmental changes and this is a new and strange thing in our meadow, so we’ll say that these spots give our special butterfly a 20% survival boost by startling birds when they come in for the kill. if our initial spotted butterfly makes it, its offspring, if they have this mutation, also have the increased survival boost! 

and if we fast-forward our meadow another 100 butterfly generations, the spotted insects will have outcompeted and replaced the original plain-winged butterflies due to being slightly better at not getting murdered by birds all the time.

but UH-oh! what’s this?

at this point, the birds are starting to catch wise to this trick! a bird that can see through the butterfly spot defense has a better chance of getting a meal, which is now putting pressure on the bird population to develop this behavior!

so what’s a poor butterfly to do?

ESCALATE, OF COURSE.

it’s this ongoing arms race between animal populations that drives natural selection, pushing prey species to develop more elaborate and effective defenses while also driving predators to develop counteroffensives! this permanent natural war continues until something upsets the system entirely, like if a meteor slammed down onto our example meadow and set the whole continent on fire.

but before that inevitably happens at some point in the far future, our plain yellow butterfly species will have developed into a whole array of species, each with their own signature alarming, obnoxious, or just plain weird set of patterns and defensive behaviors! including, yes, some terrifyingly lifelike eyespots.

and it’s all down to the magic of random chance! 

you might even call it... the butterfly effect.

I suffer for what I feel, for what I ignore and for what I invent.

One of the greatest joys of love is the feeling that the most wonderful person in the world has chosen you.

Release the stresses of the day. Become a more beautiful lovely being. Be a ball of love and light. Be careful with your heart. Take care of your body. You’re beautiful. Be kind to yourself. You’re gorgeous. You are the art you wish to admire with someone else at a museum. Nurturing yourself should be apart of your natural state. Be kind to others. Love unconditionally. Do what makes you happy. Smile more it looks good on you babe🤍

Remember the fact that someday you will die and all your achievement and failures will fade away.

Just quick a collection of exotic alien wildlife.

Tanuki are not related to raccoons? They aren't even mustelids?!?!

They are... vulpini.

(Nyctereutes or raccoon dogs include tanuki)

Welcome to the fox pile, tanuki!
