I call it a dancing tree of life

It is a classic shot of one of the main entrances to Ta Prohm Temple, but sometimes cliché becomes iconic.

The Ta Prohm is somehow most known for its tall trees and solid root system entangled in the buildings structure.

But it is also one of the more challenging temples to explore, because the structure itself, the park around it and the entrance gates. The area is so filled with interesting details and unexpected turns and ideas. This is one of the temples worth spending some time studying.

Ta Prohm (Khmer: ប្រាសាទតាព្រហ្ម, "Ancestor Brahma") is the modern name of the structure. Originally it was called Rajavihara (Khmer: រាជវិហារ, "royal monastery"). It was built during the reign of Jayavarman VII, the great ruler who is known for Bayon, the final version of Angkor Thom city and other massive social public works like hospitals and safe guesthouses all over the realm.

It was a monastery and university, build to honour the kings mother, with the gates honouring his brother and his guru. At the peak of its operation, 12 500 people lived within Ta Phrom temple complex and appx 80 000 lived in villages around it, supporting the institution.

Photo shows an old temple gate in the middle of several trees, of which one is extremely tall, white and rises as an "umbrella" over the main gate. In front of the temple gate there is a low stone bridge leading into to the fundament of the temple. The stone is coloured in shades of brown, beige and reddish. It is a sunny day and the sky in the background is blue with some light white clouds.

Nature’s resilience on full display—this incredible tree along the trail to Fern Canyon in Redwood National Park twists and thrives, defying gravity in the misty forest. A true testament to the wild beauty of the redwoods. 🌿🌲✨

Pleased to share that this photo won a blue ribbon in the 2024 Kentucky State Fair.

Scientists figure out why there are so many colorful #birds in the #tropics and how these colors spread over time phys.org/news/2024-07-scientis

Transitions between colour mechanisms affect speciation dynamics and range distributions of birds nature.com/articles/s41559-024

"They found that iridescent, colorful feathers originated 415 times across the #bird #TreeOfLife, and in most cases, arose outside of the tropics– and that the ancestor of all modern birds likely had iridescent feathers, too"

"Branches and Vines Quilt," Ernestine Zaumseil, c. 1875.

Not much is known of Zaumseil, except that she was a quilter working in the latter part of the 19th century. Too bad, as this is an exquisite work.

The center tree is very much derived from a traditional "tree of life" quilting pattern, but she added a riot of branches and leaves around it. It is known that Zaumseil used actual plants from around her home as templates for the applique here, so while fanciful, as quilts are, it's also quite realistic in its morphology of the plants.

Quilts are endlessly fascinating; the patterns, with names like Double Wedding Ring and Drunkard's Path, are amusing, but the sheer artistry that goes into some of them is staggering. This could pass for a piece of modern fabric art, and it gives me pause to look at this and realize it's 150 years old.

Plus, quilts were PRACTICAL art. They were meant to be used. I get a certain joy from the idea of something as beautiful as this being a source of physical comfort to someone on a cold night...

From the Metropolitan Museum of Art, New York.

A large quilt sewn with applique. In the center is a tree of sorts, echoeing a tree-of-life motif sometimes used in quilting. Around it are many different vines and branches of different plants, some with fruit or berries, all in full leaf, against a white background.

Happy to share the latest manuscript from our lab, in which we propose that eukaryotes evolved from a genomic chimera of Asgard archaea and giant viruses.

biorxiv.org/content/10.1101/20

This is a controversial topic, but we believe we have strong evidence to suggest a critical viral role in eukaryogenesis.

bioRxiv · Chimeric Origin of Eukaryotes from Asgard Archaea and Ancestral Giant VirusesThe details surrounding the evolution of complex cells remain some of the most enduring mysteries in biology. Recent evidence has demonstrated that Asgard archaea are the closest cellular relatives of eukaryotes, but several eukaryotic enzymes involved in key cellular processes lack phylogenetic affinity with archaea. In particular, phylogenies of eukaryotic DNA and RNA polymerases often support a 3-domain topology that is not consistent with an archaeal origin. Here we present comprehensive phylogenetic analysis of eukaryotic family B DNA polymerases and multimeric RNA polymerases and show that these core subunits of these enzymes are derived from the ancestors of modern giant viruses (phylum Nucleocytoviricota). Specifically, we show that the eukaryotic delta polymerase (Polδ), a key processive polymerase required for genome replication in all eukaryotes, clusters within an ancient viral clade, strongly supporting a viral origin. By contrast, the other eukaryotic processive polymerase (Polε), clusters within an Asgard archaeal clade. Together, these observations provide a strong and direct link between early eukaryotes, Asgard archaea, and giant viruses. Lastly, we provide a comprehensive phylogenetic analysis of eukaryotic multimeric RNA polymerases to confirm that RNA polymerase II, which is responsible for mRNA transcription in eukaryotes, is also derived from the ancestors of modern giant viruses. In total, our results support a model of eukaryogenesis in which complex cells emerged from a genomic chimera of Asgard archaea and an ancient viral lineage. ### Competing Interest Statement The authors have declared no competing interest.

#introduction
Hello everyone!
I’m an associate prof at Virginia Tech studying viral diversity. Lately my group has been focusing on giant viruses, but we are also interested in other protist viruses, and the role of viral endogenization in host genome evolution.

Recently we have been examining the strange and complex genes encoded in giant virus genomes!
