Weekly Article - Humans Or Heat?

Although it has been known for many years that humans are a significant influence in the decline and extinction of large mammals historically, it has only ever been considered one of the factors to take into account though.

Is this right though?

Well a recent (ish) study claims that the pressure applied large mammals declines because of climate are not overly significant. They suggest that humans were the sole cause of their decline.

This creates two opposing theories however; one which claims climate change caused the extinction of large mammals after the last ice age, while another believes that it was due to human influences that these creatures were lost. The climate change theory tends to believe that the larger mammals were not capable of keeping cool in the higher temperatures post ice age so they overheated and died. This study which states humans are to blame, draws on date which shows losses were greater in Euroasia and other areas where the human populations began to develop at an increasing rate while they were less effected on other continents such as Africa.
