Species Comparative Biochemistry Structures Closely Related Explain Evidence

Comparative biochemistry provides evidence for evolution by comparing molecular sequences; molecules like cytochrome c remain relatively unchanged, while minor differences in other molecules can indicate evolutionary links and the point of divergence from a common ancestor.

La biochimica comparata fornisce prove dell'evoluzione confrontando sequenze molecolari; molecole come il citocromo c rimangono relativamente invariate, mentre piccole differenze in altre molecole possono indicare relazioni evolutive e il punto di divergenza da un antenato comune.

Front Explain how comparative biochemistry provides evidence for evolution.
Back Comparative biochemistry evidence:
  • Cytochrome c and rRNA studied
  • They remain almost unchanged amont species throughout time
  • Slight changes that occur can help identify evolutionary links
  • Species with most similar structures - more closely related than those w different structures
  • To check how closely related - compare molecular sequences of a particular molecule (order of DNA bases or amino acid sequence) - can estimate the point at which the species last shared common ancestor
