Lösung anzeigen
TESTE DEIN WISSEN
  • Mutations
  • Horizontal Gene Transfer & Recombination

-> Gene Variation


  • Natural Selection

TESTE DEIN WISSEN

Whats the idea of a monophyletic tree of organism?

Who came up with it when?

Lösung anzeigen
TESTE DEIN WISSEN

Ernst Haeckel (1866)


All Organism share one common ancestor.

Häckel did not have access to Gene sequencing so he had to use morphological features.

TESTE DEIN WISSEN

"Life is the harnessing of chemical energy in such a way that the energy- harnessing device makes a copy of itself."

  • Energy conversion
  • Information storage 
  • Replication

TESTE DEIN WISSEN

What the main difference between modern Woese trees and the original one?

Lösung anzeigen
TESTE DEIN WISSEN

Nowdays we can use Metagenomes, which means that we no longer have to cultivate each species.


The abundance of species is way bigger and more complex.

TESTE DEIN WISSEN
  • Physical Compartementasation
    • barrier between different levels of entropy
  • source of energy
    • prevention of TE
  • Abiotic Polymerization of Monomeric Units
  • Catalyzers
    • promoting abiotic synthesis
  • Disposal of waster by-products

What are some problems of the Miller-Urey experiment?

Lösung anzeigen
TESTE DEIN WISSEN
  • the experiment failed to show the emergence of life i. e. a long-lasting, stable source of disequilibrium 
  • There is evidence that primarily atmosphere was unproductive: CO2, N2 and H2O and only traces of H2
  • Chirality

TESTE DEIN WISSEN

Name supporting arguments for the RNA world.

Lösung anzeigen
TESTE DEIN WISSEN
  • RNA is essential (cofactor, molecules)
    • must have evolved early
  • RNA can be catalytic active
    • may be able to self-replicate
  • Earliest viruses may have evolved from RNA genome cell-like structures


  • Proteins than replaced RNA as catalysts and DNA replaced RNA as genome and template
