The math behind evo devo - by NanoRooms

how interacting genes program the body plan

maternal influence genes determine head from tail (polarity)

gap genes determine body parts - head, thorax, abdomen

pair rule genes determine parasegments - switched on or off based on interactions between upper layers of genes

segment polarity genes determine each segment polarity

homeotic selector genes (Hox genes) - determine body parts like wings, legs, antennae - controlled by upper layers (gap, pair rule, segment polarity) (part of a larger group of genes - homeobox genes)

The Body Plan Concept and Its Centrality in Evo-Devo

by Katherine E. Willmore

> Why no new phyla have emerged in the time since the Cambrian explosion is one of biology’s great mysteries. Five major extinction events have occurred since the explosion, offering vacated niches for new body plans to evolve. Still, no new phyla have been observed. For evolutionary developmental biologists, two main questions emerge from this phenomenon: (1) what developmental processes underlie this apparent phylum-level stasis and (2) what developmental processes underlie the evolution of novel features at the class, family, and species levels. The answers to these questions are generally sought under the concepts of constraint and evolvability respectively.

occlupanids

HORG: Holotypic Occlupanid Research Group was founded in 1994 by John Daniel

the initial intention for founding HORG was a tongue-in-cheek attempt to poke fun at the politics of classification, a parody by a taxonomy-lover for taxonomy-lovers [here]

and it has a subreddit and discord, too

You know those little things that keep bread bags closed?  Well, the internet would like to tell you about them.  If you’re not doing anything too important right now, I think you should visit HORG (that’s the Holotypic Occlupanid Research Group) and explore a beautiful, obsessive, hilarious taxonomy of occlupanids.

customer review of bag of bones:

I have been buying bags of human bones for over 22 years now and have always enjoyed that first moment when I rip open the bag and inhale the somber, musky smell of decay and sadness. Unfortunately for me and my neighbors: not so this time. The smell that erupted from the bag was unholy and not unlike curdled dairy or aged cheese... also: when the sun rises, these bones float over my bed as I lay in fear, trembling, and they speak to me by rapidly vibrating the molecules of my own skin. Other than these two issues, I have enjoyed the BONES1 bag of bones very much.

the human cadaver

The human cadaver has to be classified as a distinct educational tool as it is neither the student's "first patient" nor a mere biological model. It is a non-vital, morbid and mortal, variable, and three-dimensional individual with a low health hazard and high quality of haptic experience, restricted availability and relatively moderate costs per student. It cannot be harmed by the student and its use is ethically sound.

The Necrobiome: Microbial Life After Death

halloween edition: microbes after hours - by Dr. Jennifer DeBruyn.

cadaver is a very ephemeral system - a hot spot, quite literally, because of the raised temperature from all the bacterial activity. While a tree trunk can lay in the forest for years, animal cadavers attract a lot of life (and keep "living" themselves, in a way) - not just the bacteria, but fungi, insects and scavengers. Those in turn bring their own bacteria to the party, and we see waves in the party crowd lol.

and so the corpse keeps on living. Have you heard about clandestine graves, by the way?

@yeoldedeadlights submitted: Not the nicest video, but a very busy sexton beetle doing his job in north east Scotland!

RIP to the rodent, but look at all the bugs that get to utilize it now! Nature is beautiful even when it’s gross. For anyone curious, sexton beetles are burying beetles - they bury the bodies of dead small animals, strip the fur or feathers, and line the underground chamber they’ve dug with them. Then they lay their eggs in the soil nearby and when larvae hatch they have a nice tasty meat meal. The parents will care for their babies to some extent, although they’ve also been observed culling their young if there isn’t enough food to go around. Anyhoo, cool find! Thanks for sharing!
