Humans are anatomically similar to and related to great apes, but they differ in having a more developed brain and, as a result, the ability to articulate speech and abstract reasoning. Furthermore, humans have a notable erectness of body carriage, which frees the hands for use as manipulative members. However, some of these characteristics are not entirely unique to humans. The cognitive and anatomical gap between humans and the great apes (orangutans, gorillas, chimps, and bonobos) is much smaller than previously thought, as they have been shown to possess a variety of advanced cognitive abilities previously thought to be restricted to humans.
Humans were once thought to be the only recent representatives of the family Hominidae, but new research shows that chimps and bonobos are more closely related to humans than gorillas and orangutans, and that the last common ancestor between the chimp and human lines lived between seven and six million years ago.
Definition
Homo Sapiens is the scientific name for humans. Humans are classified as Mammalia and the order Primates.
There are numerous hypotheses about humans and their existence. Aristotle, Plato and Socrates, ancient Greek philosophers, theorised the nature of human existence using fossils and other scientific evidence.
In terms of genetics, morphology, and physiology, humans share many similarities with other mammals such as chimps and bonobos, according to the fossils discovered. There are significant disagreements regarding the origins of human evolution. Chimpanzees and humans have a common ancestor in human evolution.
Human body
The human body is composed of everything that constitutes, well, you. Our genetic information determines and regulates the physical form and function of the human body; however, external environments and behaviours can alter the way our bodies look and function, according to Human Growth and Developments.The human body is made up of all the living and nonliving components that make up the human organism’s overall structure, including every living cell, tissue, and organ.
Human anatomy is composed of five basic parts: the head, neck, torso, arms and legs. Under the skin, however, there are countless biological and chemical interactions that keep the human body machine running.
Many different articles cover human anatomy and physiology. See human blood; cardiovascular system; digestive system, human; endocrine system, human; renal system; skin; human muscle system; nervous system; reproductive system, human; respiration, human; sensory reception, human; skeletal system, human for more information on specific tissues, organs, and systems. See ageing; growth; prenatal development; human development for a description of how the body develops from conception to old age.
Human body systems
1.) Circulatory system: the circulatory system is a network of blood, blood vessels, and lymph that runs throughout the body. It is the body’s distribution system for oxygen, hormones, and essential nutrients to organs, which is powered by the heart.
2.) Respiratory system: every tissue in the body requires oxygen. The respiratory system, which consists of air passages, pulmonary vessels, the lungs, and breathing muscles, delivers oxygenated blood to body tissues while also removing waste gases.
3.) Digestive system: Through a chemical breakdown process, your digestive system allows your body to convert food into usable nutrients. This happens via a system of tube-like organs such as the oesophagus, stomach, liver, pancreas, and intestines.
4.) Muscular system: The muscular system is made up of all the muscles in the body that move the skeleton, maintain posture through consistent contraction, and generate heat through cell metabolism. Muscles in humans are classified into three types.
5) Skeletal system – Bones and cartilages make up the skeletal system. The skeleton is divided into two sections: axial and appendicular. The bones of the trunk and head make up the axial skeleton. The bones of the limbs, as well as the pectoral and pelvic girdles, make up the appendicular skeleton.
6) Cardiovascular system – The circulatory system and the heart of blood arteries make up the cardiovascular system. There are four chambers in the heart: two ventricles and two atria. The top chambers of the left atria and right atria are where blood enters the heart, and the left and right ventricles are where it escapes. Backflow of blood is prevented by heart valves.
7) Nervous system – By directing the operation of the organs in our various body systems, the nervous system regulates how we interact and respond to our surroundings. The brain, spinal cord, and sensory organs make up the nervous system. Neurons connect them and act as transmitters of neural signals throughout the body.
What is the difference between being human and human being?
At first glance, the terms human being and being human appear to be synonymous; however, there is a distinction between the two terms in terms of their meanings. If you look closely at these two words, you’ll notice that the position of the word “being” makes all the difference in the meaning. In ‘human being,’ ‘being’ is used as a noun to indicate a living thing, whereas in ‘being human,’ ‘being’ is used as a verb, transforming ‘being human’ into a verbal phrase that means displaying human qualities. The primary distinction between human being and being human is that ‘human being’ generally refers to being a member of the Homo sapiens race, whereas ‘being human’ refers to exhibiting characteristics that are unique to humans.
Conclusion
Homo Sapiens is the scientific name for humans. Introduction Humans are anatomically similar to and related to great apes, but they differ in having a more developed brain and, as a result, the ability to articulate speech and abstract reasoning. The cognitive and anatomical gap between humans and the great apes (orangutans, gorillas, chimps, and bonobos) is much smaller than previously thought, as they have been shown to possess a variety of advanced cognitive abilities previously thought to be restricted to humans.
