My Science - Blog / Mein Naturwissenschaftsblog

Hopefully some interesting bits of information extracted from science and non-fiction literature. (For historical reasons there are some poems scattered throughout this blog.) Sachthemen und Sachtexte. (Historisch finden sich auf diesem Blog auch einige Gedichte und Aphorismen.) [Just collecting some exciting bits of information here.] [Eine Sammlung von interessanten Texten, Fragen und Antworten will das hier sein. Nicht mehr, aber auch nicht weniger.]

Paternal provisioning versus mate seeking in human populations

Paternal provisioning versus mate seeking in human populations
Edward M Miller; August 1994
Personal and Individual Differences

Abstract

Paternal investment theory suggests that, in cold climates males were selected for provisioning, rather than for mating success. In warm climates, where female gathering made male provisioning unessential, selection was for mating success. Male hunted meat was essential for female winter survival. Genes that encouraged mating success were selected for in cold climates. Negroids (blacks) evolved in cold climates, while Caucasians (whites) and Mongoloids (Asians) evolved in colder climates. Mating is assisted by a strong sex drive, aggression, dominance, sociability, extraversion, impulsiveness, sensation seeking, and high testosterone. Provisioning is assisted by anxiety, altruism, empathy, behavioral restraint, gratification delay, and a long life span. Explanations are offered for racial differences in many personality characteristics, hormone levels, monamine oxidase levels, testosterone levels, lactase dehydrogenase metabolic paths, life spans, prostate cancer rates, hypertension, genital (penis and testes) size, vocal frequencies, liver size, muscle structure, mesomorphy, bone density, sports performance, crime rates, rape, child abuse, earnings, age at first sexual activity. AIDs, illegitimacy, divorce, marriage, and polygyny rates. Eye color correlations are discussed. Negro family structure in the Caribbean and the U.S. may reflect selection in Africa during hunter-gather times. Comparison is made with differential K theory and father absence theories.

(Linda S. Gottfredson)

"If our professions do not allow us to devote more than two hours a day to a subject, do not abandon the work on the pretext that we need four or six. As Payot wisely noted, 'A little each day is enough, as long as a little is produced each day.' "

"So zu lesen und zu studiren, daß es sich immer ansezt, kan ich rathen, obgleich die Welt nicht an mir den Nutzen dieses Rathes sieht, ich gebe ihn nicht weil ich ihn durch häufige Erfahrung nützlich befunden habe, sondern, weil ich jezt sehe und deutlich, daß ich ihn hätte befolgen sollen."

(Georg Cristoph Lichtenberg)

"no matter who your are, your joie de vivre mostly derives from paying attention to someone or something that interests you."

(Winifred Gallagher)

"Almost anything can be interesting once. Only a few things ever become endlessly fascinating, and nothing is endlessly fascinating for everyone."

(Paul Silvia)

"Every organism, whether a bacterium or a member of Homo sapiens, has a set of things in the world that matter to it and which it (therefore) needs to discriminate and anticipate as best it can."

(John Cleese)

"The key, Paul [Silvia] explained, is that novelty for the beginner comes in one form, and novelty for the expert in another. For the beginner, novelty is anything that hasn't been encountered before. For the expert, novelty is nuance."

(Angela Duckworth)

"So I discovered early on if you want anything you went for it and you got it. And most people don't ever go anywhere or want anything, so they never get anything."

(Ray Bradbury)

"But thinking is to be a corrective in our life, it's not supposed to be the center of our lives. Living is supposed to be the center of our lives."

"the physical universe has structure, and one’s perceptions of this structure, one’s partiality to some of its characteristics and aversion to others, are precisely the elements that make up one’s taste."

(Chen Ning Yang)

Genialität als ein Etwas, das uns in die Lage versetzt, Wert zu detektieren, und das uns danach streben lässt, Wert hervorzubringen.

In seinen lebendigsten Stunden findet der Mensch Erfüllung.

Aufgabe der Philosophie: Den Charakter dieser Welt einzufangen; in deutlichen und klaren Worten. Unter Miteinbezug innerer Erfahrung.

Dem Philosophierenden geht es darum, fundamentale Einsichten in den Charakter dieser Welt zu gewinnen.

Einen Menschen sehen, in voller Stärke, ganz und gar in seinem Element ...

Der Reiz mancher Gedanken erschöpft sich nicht. An manchen Gedanken können wir wieder und wieder und wieder Anteil nehmen.

Das tun, was in der eigenen Macht liegt. Der Rest ist Schicksal.

Menschen, die auch im Schmerz noch singen. Denen der Mut nie abhanden kommt.

Freiheit: Die Bestrebung, das "Ich muss" zu entfernen, und, als Ersatz, das "Ich will" zu kultivieren.

Es gibt Richtungsentscheidungen, im Leben, die zu einem Mehr an wertvollem Leben hinführen, oder von solchem Leben entschieden wegführen.

Die Welt ist in einer Weise beschaffen, dass wir in ihr zutiefst positive Erfahrungen sammeln können.

Life comes in distinct flavors.

Every scientific field has its distinct population of ideas and statements.
