Discuss the advantages and limitations of using biological evidence for environmental reconstruction of the climate in the Quaternary period. Introduction The Quaternary period refers to our current geological time period, it spans over two epochs, the Pleistocene and Holocene, during this geological period, the world has experience incredible climatic changes that have shaped the world we live in today. The Quaternary period has been characterised by numerous periods of glaciation, due to these periods of glaciation there were fluctuating changes in climate and sea levels which have resulted in the alteration of different environments worldwide. Throughout the centuries, the Quaternary period has experienced fluctuating climates almost see-sawing between sudden periods of global warming to full blown glaciation periods covering most of Northern Europe and North America. There are many causes theorised for these fluctuating changes in climates like an anthropogenic climate change which is human caused change that interacts with natural variations and many more. It can be argued the Quaternary period is one of the best studied areas of geologic record, due to its preservation in comparison to other periods, this allows for researchers to be able to study areas like climatic reconstruction. There are many methods to reconstruct Quaternary periods using biological evidence like Pollen Analysis, Diatom Analysis and Tree Ring Analysis, which will all be explored in this essay,Show MoreRelatedEssay on The Importance of Human Evolution 1794 Words   |  8 Pageshe aimed to explain this through his theory of natural selection, genetic variation and ‘survival of the fittest’ (Ruse 2009).Through this insight gave rise to all archaeologists to search in the eastern and western African region to find fossil evidence of these apes or species we have evolved from. Through individual’s hard work and dedication we can now fill in the gaps between the different species and how we have arrived at our modern day selves. Every story has to have a beginning, middle
