Lessons in sustainability, evolution and human adaptation -- courtesy of the Holocene      (via sciencedaily.com)     Original source 

The El Gigante rockshelter in western Honduras is among only a handful of archaeological sites in the Americas that contain well-preserved botanical remains spanning the last 11,000 years. Considered one of the most important archaeological sites discovered in Central America in the last 40 years, El Gigante was recently nominated as a UNESCO World Heritage site.

'We're all Asgardians': New clues about the origin of complex life      (via sciencedaily.com)     Original source 

According to a new study, eukaryotes -- complex life forms with nuclei in their cells, including all the world's plants, animals, insects and fungi -- trace their roots to a common Asgard archaean ancestor. That means eukaryotes are, in the parlance of evolutionary biologists, a 'well-nested clade' within Asgard archaea, similar to how birds are one of several groups within a larger group called dinosaurs, sharing a common ancestor.

Cave excavation pushes back the clock on early human migration to Laos      (via sciencedaily.com)     Original source 

Fifteen years of archaeological work in the Tam Pa Ling cave in northeastern Laos has yielded a reliable chronology of early human occupation of the site. The team's excavations through the layers of sediments and bones that gradually washed into the cave and were left untouched for tens of thousands of years reveals that humans lived in the area for at least 70,000 years -- and likely even longer.

Face of Anglo-Saxon teen VIP revealed with new evidence about her life      (via sciencedaily.com)     Original source 

The face of a 16-year-old woman buried near Cambridge (UK) in the 7th century with an incredibly rare gold and garnet cross (the 'Trumpington Cross') has been reconstructed following analysis of her skull. The striking image is going on public display for the first time on 21st June, with new scientific evidence showing that she moved to England from Central Europe as a young girl, leading to an intriguing change in her diet.

Completing genome of rusty patched bumble bee may offer new approach to saving endangered bee      (via sciencedaily.com)     Original source 

A detailed, high-resolution map of the rusty patched bumble bee's genome has been released, offering new approaches for bringing the native pollinator back from the danger of extinction. Putting together the rusty patched bumble bee genome is part of the Beenome 100 project, a first-of-its-kind effort to create a library of high-quality, highly detailed genome maps of 100 or more diverse bee species found in the United States.

Study shows ancient Alaskans were freshwater fishers      (via sciencedaily.com)     Original source 

A scientific team has discovered the earliest-known evidence of freshwater fishing by ancient people in the Americas. The research offers a glimpse at how early humans used a changing landscape and could offer insight for modern people facing similar changes.

Fossil study sheds light on famous spirals found in nature      (via sciencedaily.com)     Original source 

A 3D model of a 407-million-year-old plant fossil has overturned thinking on the evolution of leaves. The research has also led to fresh insights about spectacular patterns found in plants.

First hominin muscle reconstruction shows 3.2 million-year-old 'Lucy' could stand as erect as we can      (via sciencedaily.com)     Original source 

Digital modelling of legendary fossil's soft tissue suggests Australopithecus afarensis had powerful leg and pelvic muscles suited to tree dwelling, but knee muscles that allowed fully erect walking.

Hundreds of human skulls and mandibles recovered from the Crenshaw site in southwest Arkansas are the remains of ancestors of the Caddo Nation and not foreign enemies, according to a new study.

Scientists investigate the evolution of animal developmental mechanisms, show how some of Earth's earliest animals evolved      (via sciencedaily.com)     Original source 

Lacking bones, brains, and even a complete gut, the body plans of simple animals like sea anemones appear to have little in common with humans and their vertebrate kin. Nevertheless, new research shows that appearances can be deceiving, and that a common genetic toolkit can be deployed in different ways to drive embryological development to produce very different adult body plans. It is well established that sea anemones, corals, and their jellyfish relatives shared a common ancestor with humans that plied the Earth's ancient oceans over 600 million years ago. A new study from the Gibson Lab, published in Current Biology on June 13, 2023, illuminates the genetic basis for body plan development in the starlet sea anemone, Nematostella vectensis. This new knowledge paints a vivid picture of how some of the earliest animals on earth progressed from egg to embryo to adult.

Lingering effects of Neanderthal DNA found in modern humans      (via sciencedaily.com)     Original source 

Recent scientific discoveries have shown that Neanderthal genes comprise some 1 to 4% of the genome of present-day humans whose ancestors migrated out of Africa, but the question remained open on how much those genes are still actively influencing human traits -- until now.

Team finds reliable predictor of plant species persistence, coexistence      (via sciencedaily.com)     Original source 

Ecological scientists have long sought ways to measure and predict how specific plant communities will fare over time. Which species in a diverse population will persist and coexist? Which will decline? What factors might contribute to continuing biodiversity? Researchers report on a new method for determining whether pairs or groups of plant species are likely to coexist over time.

Life before air conditioning: Curly hair kept early humans cool      (via sciencedaily.com)     Original source 

Curly hair does more than simply look good -- it may explain how early humans stayed cool while conserving water, according to researchers who studied the role human hair textures play in regulating body temperature. The findings can shed light on an evolutionary adaptation that enabled the human brain to grow to modern-day sizes.

A genomic analysis of ancient human remains from Morocco in northwest Africa revealed that food production was introduced by Neolithic European and Levantine migrants and then adopted by local groups.
