☆ To Cure to Burnout, Embrace Seasonality - The New York Times
▼ + stars: | 2024-02-16 | by ( Cal Newport | ) www.nytimes.com time to read: +1 min

For most of human existence, the pace and intensity of productivity varied widely from season to season. Following the development of agriculture around 10,000 B.C.E., the relationship between work and the seasons became even more structured, with predictably busy planting and harvesting seasons interleaved with predictably quiet winters. This led to a conception of work as something that should occur at the fullest possible intensity, without variation, throughout the year. When knowledge work arose as a major economic sector in the 20th century — the term “knowledge work” itself was coined in 1959 — it borrowed this approach from manufacturing, which was the dominant economic force of the time. Office buildings became invisible factories, with members of this growing class of workers metaphorically clocking in for eight-hour shifts, week after week, month after month, attempting to transform their mental capacities into valuable output with the same regularity as an assembly-line worker churning out automobiles.

☆ 'Intellectually inferior' humans caused Neanderthals to go extinct, a new book claims

A new book “The Naked Neanderthal” says humans were the main cause thanks to their superior weapons. Compared to early humans, Neanderthals were muscular with a prominent brow and less pronounced chin. Since humans were the final species to occupy the cave, Slimak argues it's because they'd replaced those Neanderthals by wiping them out. Humans' superior weaponsScientists have found relatively few weapons belonging to Neanderthals , Slimak wrote. Yet genes can't tell us much about the nature of these interactions or how closely or amicably humans and Neanderthals lived.

Modern humans, or homo sapiens, weren’t previously known to have lived as far north as the region where the tools were made. “The Ranis cave site provides evidence for the first dispersal of Homo sapiens across the higher latitudes of Europe. It also shows that Homo sapiens, our species, crossed the Alps into the cold climes of northern and central Europe earlier than thought. Using the same technique, the team also managed to identify human remains among bones excavated during the 1930s.

☆ How head lice reveal secrets about human origins

CNN —Head lice have been constant, if unwanted, human companions for as long as our species has been around. Some 20 years ago, David Reed, a coauthor of the new study and a researcher and curator at the Florida Museum of Natural History, found that human head lice are composed of two ancient lineages, with origins predating Homo sapiens. Doing so allowed researchers to detect the hybrid lice and better capture the genetic diversity of head lice. Ascunce said she had hoped the information they gleaned might answer whether Neanderthal head lice are still around today, but the 15 genetic markers, known as “microsatellites,” that they studied in the lice nuclear DNA didn’t reveal that information. “New ongoing studies are being done using whole genome sequences from human lice, so stay tuned for more exciting research on that.”

"So what's puzzling is that an area where we've never found any Neanderthal remains, there's more Neanderthal DNA," study author Mathias Currat, a geneticist at the University of Geneva, told CNN.

CNN —A new analysis of ancient genomes is deepening scientists’ understanding of the Neanderthal DNA carried by human populations in Europe and Asia — genetic traces that may have medical relevance today. The researchers found that, over time, the distribution of Neanderthal DNA didn’t always look as it does now. This resulted in a lower proportion of Neanderthal DNA observed in European genomes during this period. “The thing was that they had less Neanderthal ancestry so they diluted the (Neanderthal ancestry) in European populations,” Currat said. For example, Neanderthal DNA may play a small role in swaying the course of Covid-19 infection, according to a September 2020 study.

This paper is that corroborative exercise," added study co-lead author Kathleen Springer, also a USGS research geologist in Denver. Scientists believe our species entered North America from Asia by trekking across a land bridge that once connected Siberia to Alaska. The researchers also used optically stimulated luminescence dating to determine the age of quartz grains within the footprint-bearing sediments. "And just like today, if anyone walks in a similar setting, their footprints are preserved if they are covered with another layer of sediment," Springer added.

In the past few months alone, researchers have linked Neanderthal DNA to a serious hand disease, the shape of people's noses and various other human traits. Research shows some African populations have almost no Neanderthal DNA, while those from European or Asian backgrounds have 1% to 2%. For example, Neanderthal DNA has been linked to auto-immune diseases like Graves’ disease and rheumatoid arthritis. The list goes on: Research has linked Neanderthal genetic variants to skin and hair color, behavioral traits, skull shape and Type 2 diabetes. Researchers found the skulls of domesticated dogs in Homo sapiens sites much further back in time than anyone had found before.

The rarity of wood preservation at early archaeological sites - it is perishable over time - means scientists have little understanding of how early humans used it. "Wood can be shaped into a variety of forms making it an excellent construction material that is strong and durable," Barham added. The Kalambo Falls logs were determined to be from about 476,000 years ago. Wooden tools for foraging and hunting are known from about 400,000 years ago. "Use of wood in this way suggests the cognitive ability to these early humans was greater than we have believed based on stone tools alone."

CNN —Ancient humanity was almost wiped out about 900,000 years ago when the global population dwindled to around 1,280 reproducing individuals, according to a new study. What’s more, the population of early human ancestors stayed this small for about 117,000 years. The population bottleneck coincided with dramatic changes in climate during what’s known as the mid-Pleistocene transition, the research team suggested. While ancient DNA has revolutionized our understanding about past populations, the oldest DNA from a human species dates to around 400,000 years ago. “The proposed bottleneck needs to be tested against human and archaeological evidence,” they added.

REUTERS/David Mdzinarishvili REUTERS/File PhotoAug 10 (Reuters) - Long before our species Homo sapiens trekked out of Africa, earlier human species also spread to other parts of the world. The frigid interval - comparable in intensity to the more recent ice ages - appears to have rendered Europe inhospitable for the bands of early human hunter-gatherers, as extreme glaciation deprived them of food resources. Fossils and stone tools indicate that Homo erectus established a foothold in Eurasia and later southern Europe relatively early in its history. The human species who subsequently colonized Europe proved more resilient amid persistent glacial conditions. "The study provides insights into the initial vulnerability of early human species to environmental changes and how eventually they adapted to increasing glacial climatic stress," Timmermann said.
