Mitochondrial DNA (mtdna) recovered from a fossil hominin from sima de los huesos in northern spain shows connections to the mtdna of the Denisovans.
The Sima de los Huesos showed distinctive proof of DNA survival over an extended period of time. Based on the enzymatic amplification of a few short mitochondrial DNA (mtDNA) fragments from Middle Pleistocene cave bear bones. Given that the Sima de los Huesos fossils have Neanderthal-derived characteristics (such as in their dental, mandibular, midfacial, supraorbital, and occipital morphology), it is unexpected that the mtDNA from these fossils has a common origin with Denisovan rather than Neanderthal mtDNAs.

Keystone species are species
whose roles have a large effect on the types and abundance of other species in
an ecosystem. Keystone species are important in the ecosystem as they help to
determine the whole ecosystem and without them, the ecosystem would be different
or stop to be in existence. Almost all animals that have a significant impact
on the food webs are examples of keystone species.
