bet365 best casino games Recent，The official website of York University in the UK，The international scientific research team composed of research institutions such as York University and Copenhagen University in Denmark first extracted a complete ancient human genome from outside the human body，This breakthrough will provide richer information for ancient genes and prehistoric social research。

It is reported，The scientific research team extracts a complete ancient human genome from a "ancient gum" unearthed from Danish 5700 years ago。Research Discovery，This "ancient gum" is a glue material obtained after heating the birch bark，In ancient times, it is usually used as glue，To stick the stone tools to the wooden handle。Its use also includes toothache、Clean teeth、Inhibit hunger, etc.，or just use it as a gum to chew。

The first author of thesis、Researcher Theis Z. T. Jensen, a researcher at the University of Copenhagen, Bet365 app download said，This "gum" comes from Syltholm, the largest stone instrumentation site in Denmark。Archaeological results indicate，People who lived on the site in the Neolithic era began to develop a large number of natural resources，This is also the first time when farming and domesticated animals have been introduced into southern Europe。He also introduced，Hilsom archeological site is very special，Almost everything is sealed in the soil，This makes the organic residue preserved very well。

Studies show，This sticky "gum" has been chewed by a girl，DNA traces of bet365 Play online games plants and animals were also found in "gum"，Mainly hazelnuts and wild ducks，It means that this girl may eat hazelnuts and wild duck meat before chewing "gum"。Girls have a closer kinship with the hunting collectors from the western European continent，and far from the hunter collectors in central Nordic。This girl may have dark skin、Dark hair and blue eyes，Its physical characteristics are similar to today's Europeans, but they are not the same。

Researchers also said，The rise of ancient genetic research has completely changed our understanding of prehistoric history。bet365 live casino games but but，One of the important prerequisite for starting this research is to get a suitable sample first。
