Which explanations most likely the reason for the evolution of the larger brains and human?

The reason is that of the significance of the brain in human existence. In biology, the traits that provide an advantage in the environment are preserved and improved upon.   Therefore, as humans continue to use their brains to influence their environment, as the society rewards those with higher intelligence (associated with bigger brains),the bigger brains will be favored by natural selection.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
