ancient: they date back at least 700 million years, to the time when there was a
common ancestor of roundworms and human beings.

ancient language - processing mechanisms are, she adds: «Evolutionarily, this could go far beyond primates to a
common ancestor for all mammals.
By analyzing its evolutionary history, the researchers found that CVDE most likely evolved from an
ancient enzyme that was present in the
common ancestor of green algae and plants.

common to mushroom bodies in all of the investigated species, suggesting its inheritance from an
ancient ancestor, possibly 600 million years in the past.
Although the bacteria shared
common features (most live inside animals and many cause disease), the pattern of species carrying and lacking the gene suggested that the gene had been shuffled horizontally in the family tree, between distantly related species, not passed down from an

ancient specimen, which has been radiocarbon dated to 35,000 years ago, reveals that the Taimyr wolf represents the most recent
common ancestor of modern wolves and dogs.
Important links in the fossil record also remain unaccounted for, such as the
ancient last
common ancestors connecting entire phyla.
By examining fossils of early hominins, researchers have found that humans and chimpanzees may have split from their last

In the first model (Fig. 3B), the population including our
ancient horses and their descendants first separated from
common ancestors of domesticated horses and Przewalski's horses, and later admixed with the population ancestral to domesticated horses after it diverged from the Przewalski's horse population.
Our analyses indicated that the
ancient horses from Taymyr split from the
common ancestors of domesticated and Przewalski's horses at least 127 — 159 kya (credible interval = 89 — 211 kya; SI Appendix, Table S20).
We first calibrated the whole - exome phylogeny using the time to the most recent

But
ancient - DNA sequencing is beginning to shed some light on the issue.11 For example, by comparing a human HAR sequence with the HAR sequence of an archaic hominin, researchers can estimate if the HAR mutated before, after, or during the time period of our
common ancestor.12 This approach has revealed that the rate at which HAR mutations emerged was slightly higher before we split from Neanderthals and Denisovans.3, 13 As a result, most HAR mutations are millions of years old and shared with these extinct hominins (but not with chimpanzees).
