APES AND MAN HAVE COMMON ANCESTORS, WHO LIVED AROUND 7 TO 8 MILLION YEARS AGO. THE PATH OF EVOLUTION WAS BIFEERCATED IN THE FOLLOWING WAY: ONE PATH LED THE PREHISTORIC MEN TO BECOME HOMO SAPIENS AND THE OTHER TO THE APES LIVING TODAY. THE COMMON ANSESTORS, HOWEVER, HAS BECOME EXTINCT.

EVOLUTION OF MAN

Did you know that every part of your human body is made of tiny, microscopic cells? Did you know your body is organized into distinct systems that have different functions? Learn more about this and much more.

Human body, the physical substance of the human organism, composed of living cells and extracellular materials and organized into tissues, organs, and systems. Humans are, of course, animals—more particularly, members of the order Primates in the Subphylum Vertebrata of the phylum Chordata. Like all chordates, the human animal has a bilaterally symmetrical body that is characterized at some point during its development by a dorsal supporting rod (the notochord), gill slits in the region of the pharynx, and a hollow dorsal nerve cord. Of these features, the first two are present only during the embryonic stage in the human; the notochord is replaced by the vertebral column, and the pharyngeal gill slits are lost completely. The dorsal nerve cord is the spinal cord in humans; it remains throughout life.

The circulatory system is a body-wide network of blood, blood vessels, and lymph. Powered by the heart, it is the body’s distribution system to organs with oxygen, hormones and essential nutrients that helps it function properly. 

Every tissue within the body requires oxygen to function. The respiratory system, which includes air passages, pulmonary vessels, the lungs, and breathing muscles, provides oxygenated blood to the body tissues and removes waste gases. 

The digestive system enables your body to convert food into usable nutrients through a chemical breakdown process. This occurs through a system of tube-like of organs, including the esophagus, stomach, liver, pancreas, and intestines. 

The skeletal system gives the body its basic framework, providing structure, protection, and movement. The 206 bones in the body also produce blood cells, store important minerals, and release hormones necessary to life.
