New DNA evidence suggests that Hippos survived the icy period in Europe

Hippos from Central Europe was considered to be almost 115 115,000 years ago when the moderate conditions in the region turned into a icy form with the last international era and the beginning of the last icy period.

A new study that appeared Existing organisms Hippo’s history timeline is re -written in Central Europe, using radio carbon dating on Fusil is a German -rich site from Germany, a German -rich site that works for the past natural orchy of the continent’s climate.

Researchers discovered that when the climate cooled 115,000 years ago, they were not found to be widely erased. The fossils were about 47 47,000 to 31,000 years old, suggesting that the great creature was kept longer than expected, which lives deep in the last ice age.

The hot summer of Central Europe soon took the icy days and nights during the last ice age, known as the Vichelin Glacation, which began about 115 115,000 years ago and continued for about 11,700 years ago.

Hipopus requires mild climate, which contains plenty of plants to survive, which is why they are often seen as a clear indicator of hot mutual periods. Based on this, scientists have long been convinced that the hippos disappeared from Central Europe at the beginning of the snow, when the cold conditions and the rare plants made the region inappropriate for them.

The assumption was further strengthened as to how the evidence was interpreted. The sites included in the upper Rhine Gribin were traditionally thought to occupy the shift leading to the early international era, from the last international era, the early winter. As a result, any hippo giwash discovered within these layers was automatically assigned to the eemian era.

However, the right time for Hippo’s end in Europe was uncertain, the main reason is that scientists lacked ancient DNA from these ice age giants. Without molecular evidence, they could not even decide that the European population genetically linked to the African hippos of their modern era, which did not solve the evolutionary questions.

To resolve this mystery, researchers analyzed 19 hippos fossils found in the upper Rhine Gribin and pulled out partial pelgenum from one of the samples. He then compared the ancient genetic data against modern hypo genocides to detect the evolutionary relations between the European population and today’s African hippos.

The results indicated that Ice Age Hippos has a deep connection to today’s African Common Hippos.

To determine the exact time of these animals, the team employed radio carbon dating and amino acid geographicalology. The calculation shows that instead of disappearing 115,000 years ago, as scientists once believed, the Hippo was still around 31,000 years ago, which was deep in the snow. From the same site to another ice age animal dating, such as wool mammoths and woolen rhinoceros, confirmed these results.

Hippos possibly survived because the snowy period was not permanently strict. Instead, from time to time, there were hot stages known as Intestadials, who created local refoes in Upper Rhine Gribin, with considerable irrelevant water and plants to help them. However, Genome revealed less diversity, which shows that these hippos are related to a large, isolated population rather than a large, integrated.

Researchers suggest that the survival of Hepos cannot represent the same population that maintains stubbornness throughout the ice age, but a series of short -term rehabilitation events in which the creatures move forward during the hot stages and when the situation becomes unhealthy.
