The amino acids for beta hemoglobin found in five species were compared to the amino acids found in human (homo sapiens) beta hemoglobin. the number of sequence differences was recorded. based on the molecular data, which species may be more closely related to humans? a) gorilla gorilla (gorilla) 1 b) hylobates lar (gibbon) 3 c) lemur catta (lemur) 30 d) macaca mulatta (rhesus monkey) 8

The correct answer should be option A.

It is because there is only one difference in the sequence of protein synthesized in the Gorilla gorilla and Homo sapiens.

As they have the least difference in the nucleotide or amino acid sequences of the protein they would the most closely related as compared to others.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
