Concept explainers
The human brain is a remarkable outcome that has developed due to evolution. This brain permits a human to carry out day-to-day activities such as read, write, play and appreciate music, read books and so on. This brain makes humans quantitatively different from other living organisms. But, recent research has questioned this inference.

Explanation of Solution
Clothing and imaginatively constructed shelters are examples of the human capacity to transmit their culture. None of the animals developed clothing except humans. Culture obviously, changes over time. Changes in culture can occur more rapidly. Smartphones are examples of advancement in culture, millions of people own them. Today’s population is genetically identical to the generation of our grandparents, when they were young, despite, cultural changes have occurred over 50 years. Occasionally, cultural changes can result in biological evolution. Both of them are dependent on each other. For example, lactose intolerance. Most of human worldwide are lactose intolerant.
A language is a difficult form of communication that involves speech, postures, facial expressions and so on. For communication “universal grammar” is used worldwide as it is “hard weird” into the human brain. Every human infant attempts to acquire this language. Definite attributes of the language depend on the environment of the baby. A baby in China will learn only Chinese, and one in Thailand will learn Thai. This learning procedure is the same in every case. Conversely, chimpanzees drive towards the acquisition of grammatical language. Humans communicate using words.
Human, as well as animals, think. Many examples are available to support that the animals think. Thinking of animals varies between species. Different experiments were conducted to analyze the thinking ability of the animals. However, the definition of “consciousness” is contested, Theodosius Dobzhansky, an evolutionary biologist, said “all species are unique, but humans are inquest”
Unique status in humans is not because of having attributes that are not present in other species, instead, the attributes that have developed originally developed in us. Therefore, language, culture, and consciousness in humans are surprising products of our amazing brain and they are unique.
