evolutionary folks: it occurred to me today to wonder how closely related rodents and lagomorphs are, and that's taken me down a serious

rabbit hole
but not one I can get anywhere in with my level of knowledge.

how accepted is Glires as a clade, and what's a good current source for what we know about the tree?

Hi!
Let's have this .

I'm a biology student based in Northern Germany, interested in and , especially

Currently, I'm working on my bachelor's thesis about the biodiversity of rove beetles () in a Hamburg nature reserve.

My posts will be in English and German and you'll hopefully find a lot of pictures here.

Besides , I'm also interested in , / and

I'm not new on Mastodon itself, but I missed related content, so be the change, I guess.

Living organisms are assumed to produce same- .

But this is not the case for Messor ibericus, an that lays individuals from two distinct .

In this life cycle, females must clone males of another species because they require their sperm to produce the worker caste.

As a result, males from the same mother exhibit distinct genomes and morphologies, as they belong to species that diverged over 5 million years ago.

The evolutionary history of this system appears as sexual parasitism that evolved into a natural case of cross-species cloning, resulting in the maintenance of a male-only lineage cloned through distinct species’ ova.

Defying classification, fantastical artworks reframe the racism of Carl Linnaeus

In the 18th century, the Swedish biologist Carl Linnaeus set out to classify life, creating a system of taxonomy that still endures. But, as Firelei Báez explains, his work included hierarchies of humans based on race that were ‘sheer nonsense’, embedding racist ideas into science that echo to this day.

Linnaeus: Örtaboken (Herb book), early manuscript by L., 1725. "Earliest manuscript by L." The image shows Örtaboken (“The Herb Book”), the earliest known manuscript by Carl Linnaeus, created in 1725 when he was still a young student. The page, yellowed with age, is filled with neat, handwritten text in dark ink, written in Swedish and Latin. Botanical names and descriptions are carefully arranged, often accompanied by delicate ink or pencil sketches of plants, leaves, or flowers in the margins. https://commons.wikimedia.org/wiki/Category:Carl_von_Linn%C3%A9#/media/File:Linnaeus_-_%C3%96rtaboken,_early_manuscript,_1725.jpg

🐝🌻 More than 4,000 species of wild were already thriving in when European honeybees arrived in 1622. From tiny metallic green sweat bees to bumblebees that vibrate pollen loose through buzz pollination, these native species are often more effective pollinators than their famous cousins.

Many wild bees specialize in just one or a few species, creating partnerships that have developed over millions of years where each partner's survival depends on the other.
