A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

So perfect that the poor things are doomed to have their blood harvested
We are their vampires.
The beauty of evolution. If it works, it works. Whatever they have been doing for so long is working.
Furthermore it's beautiful that the evolutionary pressure hasn't changed. That there hasn't been a benefit from any of the genetic mutations. That the evolutionary pressure still applies to this day to ensure conformance with the perfect archetype.
Also a true hero for our species, they deserve statues.
Just because your general body shape did not change does not mean you did not evolve.
Point: facts
Counterpoint: memes
😁🫠
This may seem like it's just meant to be funny, but evolution without changes in genes is literally the origin of the word "meme".
Memetic evolution (as opposed to genetic evolution) happens through passing information from generation to generation, so having the counterpoint just be "memes" is unbelievably accurate!
Nerd.
I enjoy the information. I still have to call you out.
I'm proud to have been called a nerd

Yup, things like temperature, humidity, and atmospheric makeup can change quite a bit depending on geological periods.
There’s a bit of an evolutionary necessity to adapt on those timescales.
And now they will miss out on becoming crab, those poor fools.
You fool!
Crawls sideways
We was crab all along!
They have evolved, just the body hasn't changed.
I've seen the evolution of the one to the right. It now has a USB connection on the tail.
So did they grow as a person then?
At least they don't pay taxes.
Did you talk to one?
The perfect boyfriend doesn't exi-
Apart this Horseshoe crabs are not crabs it's a own species, nearest related to spiders and scorpions. They are raised since 1970 on sea farms as blood donors, which are taken a little out before freeing the animal again. Their blood (blue) is unique, because it contains a compound that detects the slightest bacterial contamination in medications and vaccines.
It's important in medicine and Pharma industry, which also as collateral effect had avoided the extiction of this animal, which before was in a real risk.
That's a lot of blood
They do have one flaw and that's their blood being so valuable to humans.
Although perhaps that means humans will ensure their survival. So maybe even that is an evolutionary advantage
There’s been some buzz lately about a synthetic replacement for horseshoe crab blood. Once again outlasting a threat to their species while changing absolutely nothing.
I feel like I've heard of this, but it's bonkers. What is their blood used for again?
I couldn't wait for the answer
In the 1960s, scientists discovered that the sky blue blood inside horseshoe crabs would clot when it detected bacterial toxins. Vaccines, drugs and medical devices have to be sterile before they're put inside people. A better toxin-detection system meant less contamination risk for patients

Once again bonkers.
Thank you
After the perfection only can exist decay, without errors, evolution can't exist.
Looks like one of those battlebots.
I wouldn't be surprised if they find these guys on Mars soon
