hello!!:-)

hi! my name is annabelle & I’m just starting my studyblr. I’m a freshman in high school & I’m just trying to be more efficient with my time. I’ve been inspired by a lot of blogs on here but tbh i don’t really know how to tag blogs in a post. soo… if anyone wants to help me out that’d be great:) 

also i don’t have a desk so i mainly use my bed as my workspace. so if i do 100 days of productivity you’ll see my bedspread:)

i tagged the classes i’m in so if you see this post under those tags you should follow me to see my notes:-)

The Hakka are one of the major subgroups of the Han Chinese, the majority ethnicity. When someone says “I am ethnically Chinese,” that usually means Han, and Han is the language and culture promoted and spread by the modern government. Hakkas are Han, but they are a subgroup and in many ways a distinct ethnicity. They differ from other Han groups in language, culture, dress, food and history, and they make up about 3% of the population.

The modern name 客家, hak-kâ, is often translated as "Guest people.” There is some debate about whether that is the correct etymology. For one thing, “guest” might be an incorrect translation of an earlier term. For another, “guest people” only started to be used routinely to refer to the Hakka, and only the Hakka, in the 1800s. In historical Qing Dynasty sources, 客 (“guest”) often referred to the Yue (Cantonese). The label, whether it is accurate or not, has contributed to he Hakka being viewed as outsiders despite their Han status through today.

Construction crews at Oregon State University uncovered a massive femur and other bone fragments belonging to a mammoth Monday.

The bones were found during construction in the end-zone of the Valley Football Center at Reser Stadium in Corvallis.

The mammoth bones are estimated to be about 10,000 years old – crews also found bone fragments belonging to a camel and bison in the same area.

“There are quite a few bones, and dozens of pieces,” said Loren Davis, an associate professor of anthropology at OSU. “Some of the bones are not in very good shape, but some are actually quite well preserved.”

Phylogenetic analyses suggests fairy tales are much older than thought
(Phys.org)—A pair of researchers has conducted a phylogenetic analysis on common fairy tales and has found that many of them appear to be much older than has been thought. In their paper published in Royal Society Open Science, Sara Graça da Silva, a social scientist/folklorist with New University of Lisbon and Jamshid Tehrani, an anthropologist with Durham University describe the linguistic study they carried out and why they believe at least one fairy tale had its origins in the Bronze Age.

Abstract 

Ancient population expansions and dispersals often leave enduring signatures in the cultural traditions of their descendants, as well as in their genes and languages. The international folktale record has long been regarded as a rich context in which to explore these legacies. To date, investigations in this area have been complicated by a lack of historical data and the impact of more recent waves of diffusion. In this study, we introduce new methods for tackling these problems by applying comparative phylogenetic methods and autologistic modelling to analyse the relationships between folktales, population histories and geographical distances in Indo-European-speaking societies. We find strong correlations between the distributions of a number of folktales and phylogenetic, but not spatial, associations among populations that are consistent with vertical processes of cultural inheritance. Moreover, we show that these oral traditions probably originated long before the emergence of the literary record, and find evidence that one tale (‘The Smith and the Devil’) can be traced back to the Bronze Age. On a broader level, the kinds of stories told in ancestral societies can provide important insights into their culture, furnishing new perspectives on linguistic, genetic and archaeological reconstructions of human prehistory.

Mutations Accumulated During Early Migrations Out of Africa

“LAUSANNE, SWITZERLAND—Modern humans are thought to have left southern Africa in small groups some 100,000 years ago. Bands of people then traveled on to Asia, and eventually crossed the Bering Strait to colonize the Americas. But the process of natural selection is more powerful in larger populations. Laurent Excoffier of the Swiss Institute of Bioinformatics (SIB) and the University of Bern, and an international team of scientists, employed next-generation sequencing (NGS) technology to examine the genomes of individuals from the Democratic Republic of Congo, Namibia, Algeria, Pakistan, Cambodia, Siberia, and Mexico, and found that the farther away from southern Africa an individual lives, the higher the number of slightly deleterious mutations an individual is likely to have. 

“We find that mildly deleterious mutations have evolved as if they were neutral during the out-of-Africa expansion, which lasted probably for more than a thousand generations. Contrastingly, very harmful mutations are found at similar frequencies in all individuals of the world, as if there was a maximum threshold any individual can stand,” SIB member Stephan Peischl said in a press release.“ ”
