Human evolution is still happening - possibly faster than ever

Evolution is a gradual change in the DNA of a species over many centuries, occurring by natural selection when traits created by genetic mutations promote survival or reproduction in an organism.

By looking at global DNA studies, it is evident that human evolution hasn’t stopped, but is happening at a faster rate than before.

• Human beings adapt to their environments genetically, over a period of time. 
• Developing countries having populations with no access to proper health care continue to survive and thrive. 
• In countries where infectious disease outbreaks have occurred in the past, survivors develop a natural resistance to the disease and pass it on to their offspring. 
• People living in higher altitudes develop a mutated gene that increases blood oxygen content, resulting in better survival in the next generation.
