Uke 45 - Celler og ulikhet

Alt liv vi kjenner er organisk, og jordas biosfære er en kontinuerlig metabolsk omsetning som styres av gener, jfr. Postulatfri Universalhypotese…


Fra lenke 1 nedenfor:

"It is generally assumed that the complex map of metabolism is a result of natural selection working at the molecular level. 

However, natural selection can only work on entities that have three basic features: 


Fra Lenke 2:

"Membranes are very important, since they 

The latter allows the cellular system to become selfish, which is an essential condition allowing natural selection during evolution"

Cellen er grunnenheten for alt liv

Cellen har tre kjennetegn:

Informasjonen i cellekjernen  (DNA) kan dessuten gjenskape cellen.


Alle komplekse systemer/fenomener er bygget av deler som samtidig er helhet; cellen er en helhet som inngår i et organ. Organet er en helhet som inngår i en organisme. Organismene inngår i biosfæren som er livet på jorda. 


(James Lovelock (1919-2022) og Lynn Margulis (1938-2011) kalte dette for Gaia…‽)


Metabolsk omsetning av molekyler og energi drives av ulikheter (elektrokjemiske gradienter)

Livet drives av forskjeller; når forskjellene utjevnes, inntrer døden. Livet balanserer hele tiden på kanten i termodynamisk ulikevekt, mens homeostase sørger for balanse, jfr. lenke 4…


Likestilling betyr stillstand og død, omforent likeverd betyr framgang og fred…
