How Did Life Begin?: Evolutionary History

4.6 billion years ago Earth was a hot mess... literally. With an atmosphere thick with water vapor and ash from volcanic eruptions, and dust, rock, and ice flying every which way, how did life manage to develop?!

Microevolution can be used to predict longer term evolution, new study shows

Microevolution can be used to predict longer term evolution, new study shows #evolution #microevolution #macroevolution #study #climate #evolvability #change #selection #science

A new paper published in Science, Evolvability predicts macroevolution under fluctuating selection, shows that evolvability, which is the ability of populations to evolve and adapt over just a few generations, can help us understand how evolution works on deeper time scales. While our relatively stable past environment has limited selective pressures, current climate change has caused more rapid…

Hey y'all! My brother (not the one I live with) and I have birthdays fairly close together, and he'd like to get together and do some kind of joint celebration, but I have no idea what to do. He's an anti-vaxxer but is willing to wear a mask around me, but his kids won't so effectively whatever we do has to be outside Do you have suggestions of things we could do that are A. outside B. suitable for small children (youngest is old enough to run around and talk but not really reading yet) and C. no flashing lights?

I’d argue that we have excellent evidence that Diplodocus didn’t cause Gonorrhea (knowing what does cause gonorrhea, general understanding of infectious diseases, general understanding of animals).

Direct experimental evidence is not actually the only way to build scientific knowledge!

INTERVIEW 016

with. hazel callahan

includes. nerd!tutor!hazel, inexperienced!hazel, fem!reader, fingering (r receiving), oral (r receiving), tit fixations, corruption undertones, semipublic sex

→ kinktober masterlist

She’s been staring at your tits. 

Ever since you walked into the study room and shrugged your cardigan off, skin then overheated with the walk you’d completed across campus, Hazel Callahan has only looked at her notes, or your cleavage. There were maybe two times where she was able to peel her eyes away from your exposed skin to look you in the eye, but almost instantly they gravitate back downwards, as if looking at your tits was more comforting than your eyes. 

Throughout the session, as you copied down a combination of what she was telling you and her notes (an array of question marks beside words that were entirely too difficult to spell in one go), your smirk grew more and more. You figured if Hazel was going to be shameless about her staring (or perhaps oblivious), you’d be shameless about your intentions, too. 

Elbows pressing into the scarred wooden table, biceps attempting to meet each other, separated by your tits that end up squished together. She notices, of course she does, stuttering over her words and clearing her throat an alarming amount of times.

“And then just make sure you know that microevolution is whenever changes produces only after many generations, like with the ––” 

You interrupt her, “don’t you mean macroevolution?”, and her eyes finally snap back up to yours. Her eyebrows raised, her lips parted. 

“What?” She raises a slender finger and presses her glasses up her nose. You lean a little closer, smile a little bigger. 

“You said microevolution. But you described macroevolution.” Hazel sits for a second, eyes lifting as she looks at the ceiling in thought, and just when they lower, assumingely to find your tits again, you speak once more. 

“Maybe we should take a break? You seem a little out of it, don’t you think so, Haze?” It’s a nickname you’d never called her before, and you lay it on extremely thick for the first time, dragging the syllables out and layering them with heavy sultriness. 

The intended effect is achieved; Hazel with wide blue eyes and red cheeks. 

“Uh, yeah, s-sure.” 

The proposed ‘break’ turns into you teaching Hazel something for once. 

Her head is just visible enough in the space between the table and your lap, her eyes shining with wonder beneath her glasses, even in the shadows she sits in, the tips of her fingers just breaching your leaking entrance. 

“Like this?” She asks, all shy and timid and it’s so cute that you’re grinning instantly. 

You nod. “Yeah. Keep going.” 

She does as told, sliding her fingers into your wet heat knuckle by knuckle, her pace agonizingly slow as if she’s afraid of hurting you. You attempt to hint to her that you’re not breakable whenever she has two fingers in you to the last knuckle, and they sit still, clearly unknowing on what to do next. 

You start to grind, holding onto the arm rest of the chair you sit in, spreading your legs even further as you push and push your hips into Hazel’s hand. She stares at you all the while, starstruck, mouth agape. Adorably, you notice her glasses starting to fog up, too. 

It takes her a moment, but she starts to move her fingers until you’re meeting in the middle with your combined movements, her thrusts and your steady push and pull. 

It’s coordinated and planned for a moment, you giving Hazel simple instructions that’s easy for her to follow. 

(“To the left a little. Yes! Right there, Haze. God, don’t stop. Keep going, just like that.”)

And then, in the moment where your eyes are closed, pinched together in bliss, there’s the feeling of a tongue, wet and warm, on your clit. It’s brief, just barely more than a jerk, almost as if it’s accidental, but when you unfasten your eyes you’re met with Hazel’s mouth just an inch from your cunt, his eyes staring up at you to gauge your reaction, you realize she's done it on purpose.

“Again.” 

She repeats it, this time swirling her tongue around your clit just before gliding it down the area beneath it. She’s clearly inexperienced, licking around your cunt in a non-uniform fashion and her glasses nudging against your skin each time, but her fingers are still probing that spot within you and the stimulation of her muscle against you is enough to have you losing it. 

You’re close, back arching, hips pushed further into Hazel’s mouth. Your hand finds her short hair, nails digging into the fragile strands at her scalp, perhaps a little too harshly. But it’s not like she cares about your intensity, because she slides a hand up your chest and pulls the neckline of your tee down, audibly groaning whenever she’s met with your bare tits. 

When you cum, it’s from the impressive combined stimulation of Hazel’s mouth and fingers on her dominant hand abusing your cunt, and the fingers of her non-dominant hand pinching your erect nipples.

16 Days Till Med School Entries

Today I was at the library with a really good friend of mine 🤗 we laughed too hard!

It's always so nice to have friends around especially while studying! It makes it easier since the struggle is shared lmao by this being said...*cough* @claykitty-studyblog *cough* still waiting for u to come with me 😏

I did:

Microevolution ✅️

Macroevolution ✅️

So the Preliminary SVP Schedule got released

For those unfamiliar, SVP = Society of Vertebrate Paleontology

usually when paleontologists say "SVP" they mean specifically the conference that SVP hosts each year, one of the biggest events for the "spends their lives studying old bones" people each year

each day has six sessions - three in the morning, three in the afternoon - and they're packed with talks. like, if you want to see talks in two different concurrent sessions, you gotta run around like a maniac

anyways

Wednesday Morning has Sauropods & Ornithischians, Early Mammals & Carnivorans, and then Fishes & Amphibians as three different sessions (all of these are groups of three going forward)

Wednesday afternoon has Dinosaur Soft Tissues, Ungulates, and Marine Reptiles

Thursday Morning has Romer Prize (fancy student talks), Birds, and Preparators' Session

Thursday afternoon has Theropod Flight Origins, Mammal Paleoecology, and Sauropsids

Friday morning has Euarchontoglires & Xenarthra, Archosaurs, and Methods & Paleohistology

Friday afternoon has Actinopterygians, Crocodylomorphs & Turtles, and Paleoecology & Paleoclimatology

Saturday morning has Theropods I, Afrotheria & Mammal Macroevolution, and Synapsids

and Saturday afternoon has Theropods II, Marine Mammals & Bats, and Squamates

The fact that Theropods get four separate focused sessions while Ornithischians and Sauropods are smushed into one is... well, I'm laughing my head off at Theropod bias right now

would you like theropods? Or more theropods? How about some THEROPODS

[hapalopus]

Macroevolution.net is not a reliable source - the site was created to push an "alternative theory of evolution." It's basically a creationist website with extra steps

A better source on hybrid animals is Messybeast:

Is this real, or an AI generated image? At this point, I cannot tell, and your taxonomy research always seems so thorough.

Having trouble finding the original source of those photos, but lion x leopard hybrids do exist. Here's a site that has more info on feline hybrids which includes one of these photos as an example. They don't occur in the wild due to the species being natural competitors and are the result of people breeding female African lions and male leopards in captivity.

Awesome new video on conservation and the Jurassic Park/World movies!

Completely unrelated, but I'm actually a current UChicago PhD student studying paleontology (+ macroevolution and a litany of other stuff), and I'm wondering which evolution/paleo-centric classes you took.

I managed to squeeze into Dinosaur Science during my last semester of 4th year. I dunno if Paul Sereno would remember me, but if you see him, tell him I say hi!

[script-a-world]

Submitted via Google Form:

I have a world in which evolution changes rapidly because there's a magical component to it because there's a ancient population of shapeshifters whose DNA is in just about everyone's ancestries. Problem is, I'm having trouble trying to define rules as to what makes sense and how quickly/slow certain changes can be? I'm talking mostly on the microevolution scale but sometimes it definitely results in some macroevolution. People are not chameleons, no. I mean like, I hear that skin colour is macroevolution, but in my world it's microevolution and it changes when people move around. It doesn't take 10000 years it takes maybe 50 years.

Tex: 10,000 years to 50 years seems to be the ratio you already want to work with, and it seems as good of a pick as any when it comes to worldbuilding in a fantasy world. What aspects are important in your worldbuilding, and is this something you require for the development of a plot, or something to answer questions that you’re using worldbuilding to address?

Addy: If skin color (or other things) can change within a person's lifetime, that doesn't seem like actual evolution. Seems more like epigenetics to me, albeit particularly slow-acting.

Evolution is a gradual process where random changes in the genome either fit or do not fit their environment. If the genome change fits, it's likely that the bearer of that gene will live long enough to have children. Random genes pop up all the time, it's just that many of them aren't helpful. That's why evolution takes time - you only have a chance to change at each new generation.

If you've got shapeshifters and people with hyperadaptability, there seem to be two approaches to me.

One, epigenetics. People have these genes, but they aren't always expressed. Think of how animals have summer and winter coats, and animals kept indoors have thinner winter coats. Birds change their plumage depending on the season. Goats in colder weather will grow finer coats than goats in warmer weather (which is why the most expensive cashmere comes from very cold mountainous regions). So your people have all these genes, it's just a matter of whether or not those genes are activated at the moment. This could work extremely quickly, on a matter of weeks or months.

Second option is a magic handwaving. Maybe each region of the world has its own magical frequency (like how the background noise of songbirds, insects, etc is different depending on what species are native), and people's bodies slowly "tune into" that natural regional frequency. So their bodies express effects more suited to that frequency as they tune in, and any children born are born with their parents' tuning.

If you wanted to have generational changes but not changes-in-a-living-person, the adaptation/tuning phase could be limited to gestation or early childhood.

But straight genetics... genetics don't change over the lifetime of an individual, so that's a limiting factor. You can work around it with other things, but genetics just aren't suited for that.

if I was the macroevolution dot net guy i think i'd believe hummingbirds are some sort of kingfisher / sweat bee hybrid.

[creature-wizard]

The thing is, questions like "what if there was something to these ancient stories?" and "what if the gods of ancient religions were actually extraterrestrials?" were never bad questions to ask in and of themselves.

What was bad was trying to push stuff like Atlantis and ancient aliens as scientifically valid while doing zero scientific research and deliberately ignoring actual scientific research.

What was bad was claiming that all of it supported this cosmic spiritual reality that everyone needs to accept and believe in so they can ascend to the fifth density.

It's literally no different than the stuff young earth creationists pull. They insist that it's scientifically valid to state that the world is only 6000 years old, that "macroevolution" never happens, that Noah's flood was very real, that tyrannosaurs ate plants before the Fall, and so much other demonstrably wrong stuff. And then they claim that all of their (pseudo)science is proof that their religion is objectively correct, and you need to convert if you want to go to Heaven.

If you can understand why young earth creationists are in the wrong, you can understand why New Agers are in the wrong.
