Human uses of energy over 10‚000 years are explained in Changing Environments (Morris et al‚ 2003a). Until 10‚000 years ago humans lived as hunter gatherers in small groups‚ this changed in the current interglacial stage or Holocene with the introduction of agriculture. Figure 2.19 page 82 of (Morris et al‚ 2003b) indicates that during the early agriculturalist period humans had begun to domesticate animals that could be used for carrying and pulling. Energy use increased from 0.24 W (calculations

Memory makes us who we are. According to How Human Memory Works‚ most people talk about their memory like a thing they have‚ but memory doesn’t exist like your body does. It’s more like a concept that refers to the process of remembering. Many scientists and researchers compare the human memory as a filing cabinet with memory folders or a supercomputer in the past‚ but now people say that the average human memory is a much more complex system; memory is said to be a brain-wide process‚ not just in

With the rapid growth of technology‚ there has been a debate on how we are using technology in our life. Many people think that we are now abusing modern devices to support for our own life; while others reckon that using technology brings us just good things and make our life easier.

This stated that all animals‚ human included‚ were evolved through natural selection from single-celled organisms to the multi-cellular ones that are extant today. This laid the foundations for the study of genetics‚ which was advanced by Watson and Crick who discovered the way DNA‚ the chemical code in each cell nuclei‚ could replicate itself. In June 2000‚ the first draft sequence of the human genome was published‚ representing a breakthrough for the Human Genome Project. The religious explanation

Overall‚ I agree with the message of the Human Being‚ Human Nature reading. I believe that at our core‚ we want to do good.

We are far more complex than any
