Explanation:
Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected

The shortening and broadening of pelvis in hominins was the indicative of habitual bipedal locomotion.
Hominins are the tribe that belong from the sub-family Homininae. They are considered as the first modern humans. They are believed to be our recent ancestors. Homo sapiens species is evolved from this tribe. The various anatomical evolutions in them were: erect posture , larger brains, bipedal motion, broadened pelvis, usage of tools and also they were known for communication.
Pelvis is the area between the lower abdomen and the hip bone. It comprises of bladder and rectum. Some of the reproductive organs of the males and females are also located in their respective bodies.
