Sagot :

Based on the similarity in protein sequence, the most closely related species are unknown species and species IV.

Which species are related by way of common descent?

From the data provided:

  • Unknown species: ACT GCA CCC
  • Species I: ACA GCA CCG
  • Species II: ACT GGT GGA
  • Species III: ACA GCA GGG
  • Species IV: ACT GCA CCG

Based on the similarity in protein sequence, the most closely related species are unknown species amd species IV.

Therefore, the most closely related species are unknown species and species IV.
