A post-genomic view of behavioral development and adaptation to the environment

A post-genomic view of behavioral development and adaptation to the environment
Peter LaFreniere and Kevin Mac Donald; 2013

Abstract

Recent advances in molecular genetics are reviewed that have major implications for the biobehavioral sciences and for understanding how organisms adapt to their environments at both phylogenetic and ontogenic levels. From a post-genomics perspective, the environment is as crucial as the DNA sequence for constructing the phenotype, and as a source of information in trying to predict phenotypes. The review is organized with respect to five basic processes by which phenotypes adapt to both recurrent and novel environmental challenges, with an emphasis on the data for humans: 1) developmental plasticity, 2) epigenetic mechanisms, 3) genotypeenvironment correlations, 4) gene x environment interactions, and 5) domain-general psychological mechanisms.

(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.' "

"I have always fiercly defended the position that we should base our view of the world on the state of our knowledge, on fact, and not on what we would like it to be."

(James Watson)

"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."

(Daniel C. Dennett)

"Hehle nimmer mit der Wahrheit! Bringt sie Leid, nicht bringt sie Reue; ..."

(Theodor Storm)

"Und sollt er auch straucheln überall ..."

(Friedrich Schiller)

"we don't actually go to art for information. The information content is not the primary thing. It's the experience."

(Roger Scruton)

"You have to be somebody before you can share yourself."

(Jaron Lanier)

"because when you start getting bored without constant external stimulation, that's when stuff starts coming up from the inside[.]"

(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."

(Ray Bradbury)

"when a man talks from his heart, in his moment of truth, he speaks poetry."

(Ray Bradbury)

"The PE is therefore a signal that states: 'This is good stuff, by your standards - maybe the best you are capable of, under current circumstances. Don't ignore it, don't forget it, and try to understand it'."

(Bruce Charlton)

"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.
