Scientists have extracted certain ancient tools in China which may suggest presence of primitive humans in that region as far back as 2.12 million years. This extract is older by at least 270,000 years than the preceding oldest evidence, consisting of stone tools and bones found in Dmanisi, Georgia. A team consisting of Chinese and British researchers carried out this study. The location of the findings, which consisted of stone artifacts, was at Shangchen in North China. However, the knowledge regarding the human species that made these tools is still unknown.

The discovered stone artifacts contain various kinds of tools made for various purposes, with all showing signs of use. Quartz and quartzite were used to make most of the tools which were from the nearby Quinlang Mountains foothills. Even though it was known that human beings left Africa many times, there was no previous evidence of humans occupying places in Eurasia, before evidence was discovered in Georgia. Researchers said that with this discovery, it was important to consider the time when ancient humans had left Africa, as well as when first humans showed their presence in Asia. The discovery additionally showed that the early human survived in various climatic conditions in northern part of China. Scientists suggested that dispersal of early humans to the higher latitudes showed the continuous evolution of adapting to colder weather conditions.

Meanwhile, whale bones have been discovered at ancient Roman ruins, which points to their hunting by humans at least 2000 years back. Genetic fingerprinting evidences find presence of right and grey whales in Mediterranean Sea. The discovery suggests that Romans would have had easy access to grey and right whales; however, it is still unknown whether there was presence of a Roman whaling industry. Before this discovery, Basques were thought to be involved in whale pursuits for economic gains, as early as in the 11th century. The whale bones meanwhile may provide their ecology including their historic range as well as where they used to calve.
