EVOLUTION

THE ORIGIN OF LIFE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Biochemical Evidence for Evolution relates to ____
A
Similarities in function of tissues and organs amongst species
B
Similarities in the sequence of genes and proteins amongst species
C
Similarities on behavioral strategies amongst species.
D
Is something that has not been studied by evolutionary experts
Explanation: 

Detailed explanation-1: -The more similar their DNA is, the more similar their proteins will be and the more closely related the organisms are likely to be. Thus, scientists use biochemical evidence (the amino acid sequence of proteins) to establish how organisms have evolved.

Detailed explanation-2: -Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.

Detailed explanation-3: -Explanation: Biochemical similarity is an evidence of evolution of varied forms of life from a very distant common ancestor.

Detailed explanation-4: -That two species and their common ancestor have similar DNA is strong evidence supporting evolution. Protein amino acid sequences can also be used to compare similarities between species. Proteins are made from amino acids and the sequence of these amino acids is controlled by genes.
