Human behaviour is both part of nature and nurture. The genes that define each of us are the way nature expresses itself. Nurture offers us other things that nature failed to give. One of these things is culture. According to the book “Anthropology: The Human Challenge”‚ culture is “a society’s shared and socially transmitted ideas‚ values and perceptions‚ which are used to make sense of experience and generate behaviour and are reflected in that behaviour.” To simplify‚ culture is the customs‚ arts

evolve over time to adapt to their environment. He believed that living things experience changes in their genetics which lead to a change in their characteristics. With this in mind Darwin came to conclusion: Natural Selection. Natural selection is an event that cause evolution and happens naturally and will cause organism to adapt to their environment as best they can and they pass their genetic characteristics to the next generation. With the knowledge that a desired trait of an organism can be passed

Describe Natural selection takes the raw material of variations with a population and moulds it over a long period of time into a population that can compete most effectively with other species. This selection will favor the fittest individuals in a species to fit a particular biological niche. Any given environment will have a large number of niches‚ for example small variations in the temperature‚ humidity and exposure to sunlight will affect the ability of certain plants to grow and compete

These ecosystems are involved with human lifecycle as they furnish us with water‚ food and energy.

It includes the concepts of species diversity‚ habitat diversity and genetic diversity. Species diversity: Both the range and number of organisms found in a single place or habitat – how many species and how many of each Genetic diversity: Range of genetic material present
