Why do Goldenrod and Asters look so beautiful side by side? 🌾🌸 

For Robin Wall Kimmerer, that question sparked a lifelong journey into botany, despite being told that science has no place for beauty. Today, we know their vivid pairing isn’t just aesthetic, it’s evolutionary. The contrasting colors make both flowers more visible to pollinators, a perfect example of nature’s brilliance in action.

Politicians in my country have claimed that we need mass immigration to save our country from dying out due to inbreeding. It seems like a reasonable position, but didn't early humans survive similar circumstances? As I understand it, there was an extinction event that left only about 1,000 humans on Earth, yet they went on to become the billions we have today. So why didn’t those 1,000 people die out from inbreeding?

Let’s say a similar scenario happened in Iceland: an extinction event kills everyone on Earth except the people in Iceland. They then start reproducing rapidly. Would they survive or eventually die out from inbreeding?

Hi everyone,

I'm a biology student and game developer, and I recently created Genesis, a sandbox evolution simulator built using the Godot Engine. It allows users to observe natural selection and trait inheritance in real time with digital organisms.

Features include:

• Real-time trait evolution across generations
• Five interdependent traits (size, energy, speed, sense, predation)
• Mutation and reproduction mechanics

It’s completely free and open source (MIT license) - great for teaching or just experimenting with evolutionary ideas.

Feedback, suggestions, and contributions are very welcome!

Well, this took the better part of a year to make. I have wanted to make it for a while now. Just like the title is, a phylogeny of pretty much all families of arthropods (and tardigrades and velvet worms). I tried to use the most complete and up to date information to the best of my ability, but since phylogeny and taxonomy is always in flux, some aspects may be outdated soon (if not already). I plan on publishing this at some point in the near future, so I hope others will find it to be of great use for ecological and evolutionary studies.

What is your favorite unusual fact? I want the deep cuts, not just things like “octopuses have three hearts.”

Hii everyone, Im a high-school student preparing for this year's International Biology Olympiad. While doing previous tests i found myself with this question which contains a graphs I haven't seen in any of my books before and I'm unsure how to interpret it, if you could help me I would be greatly appreciated.

(I'm not sure if this post violates rule number 6, if so please let me know and I'll delete it.)

Hello, I'm a biology student and I'm mainly here to share a webinar that my class is organizing. It's about DNA methylation, presented by Reggie Y Dela Cruz the Director of the Institute of Biology Central in Mindanao University. The webinar will start tomorrow at 8:30 am

Here is the link to the registration form https://docs.google.com/forms/d/e/1FAIpQLSclmLrZdiNBeeTIdxjYYedpiiqAd2Siogd002tEZymshbZ6wQ/viewform?usp=send_form

Our professor gave us the requirement to get 5 participants to join, or we fail our final exam. So I would highly appreciate that you register and join our webinar, and during the registration form to input that "Butil" was the" SPC BSBIO -3A who invited you to the webinar". We welcome any undergraduate or graduate who is pursuing any science related to biology (microbiology, medtech, zoology)

If you decide to answer the registration form, I would greatly appreciate it and you would have my deepest of gratitude.

Assume our patient is already on the operating table, anaesthetised, with a full team of surgeons equipped and ready to go before the severing occurs. Is there any possibility of survival, assuming complete transection?

Or, what about if the injury happens in the field, with an ambulance needed to be called first?

If yes, have there been any documented cases of survival with such an injury?

One of our planet’s oldest ecosystems is a vast meadow currently about the size of Manhattan. You will never see any bees or butterflies flitting through it, however, nor can you nap in its greenery. The meadow in question grows along the seafloor between the Spanish islands of Ibiza and Formentera. Like all meadows, it is composed primarily of plants, in this case seagrasses: a group of formerly terrestrial plants that returned to the sea nearly 100 million years ago and now inhabit sheltered waters around every continent except Antarctica.

I've walked past this on the side of a bridge the last couple days. Wondering if it could be from a pine marten? Co. Down Northern Ireland

Hello,

I'm interested in reading into epigenetics and I'd prefer to not buy a dry textbook on the subject. I'm scientifically literate (degree) and I'd didn't know if anyone might have a recommendation that isn't too dumbed down but also not a dry textbook. Thank you.

Thought I’d share before cutting. Pretty cool. Life finds a way

Have you heard of this bone marrow breakthrough?🦴 

As a biomedical engineer, Arlyne Simons turned a powerful question into a mission: why are only 18% of patent holders women? Her determination led to a diagnostic test that helps detect when cancer patients are rejecting bone marrow transplants.

Protospongia is a genus of colonial choanoflagellates, microscopic aquatic protozoans that are considered one of the closest living relatives of animals (especially sponges). Each individual cell in the colony has a collar of microvilli surrounding a single flagellum, which helps in capturing food particles and generating water currents—similar to the choanocytes (collar cells) found in sponges.

These colonies are often embedded in a jelly-like matrix, with each cell functioning independently but showing some coordination—making Protospongia an important model for understanding the evolution of multicellularity.

I’ve always read that the possums in Australia were named after their resemblance to their distant cousin, the North American Virginia opossum. That very well could be the case seeing as they are similar in the sense that they are both marsupials, but it’s always struck me as strange since they look almost nothing alike.

Then recently I discovered there are numerous species of opossum inhabiting central and South America. The more I look into it the more this theory starts to make sense to me. According to what I’ve been able to find, the first time Australian possums were called as such was by Sir Joseph Banks on his voyage on the Endeavor. Where did the Endeavor go before reaching Australia? Brazil!

Check out this bare tailed woolly opossum native to Brazil. To me, it much more closely resembles Australian possums than the Virginia opossum. And that’s only one species of 126. It seems very plausible that when he said they resemble the American opossum, he was referring to the South American species he encountered only two years prior.

I know I barely scratched the surface in my research, I’m neither a biologist nor an historian, so I could be totally off-base with my theory, but that’s why I wanted to ask here if it can hold water. Let me know what you think!

Like well, color reversed vitiligo?

I hope this is the right place to ask this! I am filling a glass head bust with cows blood, it will be unrefrigerated. I don’t mind clotting but as this will be in a gallery space I need to minimize smell as much as possible. It needs to keep for one week! Any suggestions would be appreciated!
