To see the difference between <span>biped and a quadruped,</span> let's compare the skeletons of the man (biped) and the horse (quadruped):
*The man has the bigger pelvis: he has to bear the weight of the body.*The scapula is smaller.*The bones of the hind leg bigger.*The forearms more mobile.*The man has the spine that attaches under the skull.*And the tail that has completely regressed.
the man has adapted to standing and biped (he walks on 2 feet): his hind legs are reinforced.
Global winds rising near equator and cold air sinking near the poles

This is untrue. The mantle is far large than the crust and there are other large size differences.
Chromosome number varies from one organism to another. or example, humans have 46 chromosomes while bacteria have only one chromosome.
The problem associated with the chromosome number of various organisms faced by evolutionists is that with the decrease in the size of an organism, the number of chromosomes also decrease. Thus, it becomes difficult to find and study the chromosomes.
