まとめ
古代のゲノムは東南アジア (SEA) の歴史が複雑であることを示しています ホアビンの狩猟採集家と東アジアの農家が SEA を形作りました
科学分野:
- 考古遺伝学
- 東南アジアの史前史
- 人口遺伝学
背景:
- 農民による狩猟採集者の移動に関する理論が議論されている.
- 現存する仮説には,自国の農業開発や農家の拡大の"二層"モデルが含まれています.
- これらの議論を解決することは 東南アジアの遺伝的多様性を理解する鍵です
研究 の 目的:
- 東南アジアの複雑な人口の歴史を調査する
- 東南アジアの遺伝的多様性の起源に関する競合する仮説を検証する.
- 古代の移住と混合の出来事に関する高解像度の遺伝的視点を提供すること.
主な方法:
- 26人の古代人 (25人 東南アジア,1人 日本) の全ゲノム解析
- 古代のDNAを分析して 集団の構造や混入や 移住パターンを推測する
- 古代のゲノムデータと現代の集団を比較して祖先を追跡する.
主要な成果:
- 地元農業の発展も"二層"の農民拡大仮説も,東南アジアの人口の歴史を完全に説明できません.
- 古代のゲノムはホアビンの狩猟採集者と東アジアの農民から現在の東南アジアの人口への貢献を示しています
- 島東南アジアとベトナムを含む特定の地域に影響を与えた.
結論:
- 東南アジアの人類の歴史は かつて考えられていたより複雑です
- この地域の遺伝的景観を形作るには 食糧採集と農業の両方が重要な役割を果たしました
- 古代ゲノミクスは東南アジアで長年にわたる史前論争の解決に 重要な洞察力を提供しています

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Bystander Effect

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

The Sense of Self: Reflected Self-Appraisal and Social Comparison
56.1K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
