"Evolutionary history" refers to the record of how different species have changed and adapted over a long period of time, showing how they are related to one another through common ancestors. It tells us the story of how life on Earth has developed and diversified over millions of years.
Full definition
Knowing that cats have a much shorter
evolutionary history of living with humans than dogs makes these findings even more astounding!

in evolutionary history as well as human history.

long evolutionary history, it would have been the only food that was available just about everywhere on the planet, year - round.
As scientists went deeper
into evolutionary history and closer to the base of the tree of life, the harder it became to know how closely related organisms are.
This space is devoted to exploring food plants in all their beautiful detail as plants — as living organisms with their
own evolutionary history and ecological interactions.
I'm writing to get some input from you on your incredibly valuable new paper on polar
bear evolutionary history and genetics.
Human
evolutionary history suggests, according to many authors, that all humans, regardless of sex or gender, survive and thrive if they are loved and cared for.
But further studies of
viral evolutionary history may help scientists figure out whether there are species to which we should pay more attention as sources of new infections.
The whites of the eyes help others discern the direction of an individual's gaze, which is important for social interaction, but no one knows when
in evolutionary history this feature appeared.
«We demonstrate this approach works, and that it sheds new light
on evolutionary history for the most species - rich group of marine vertebrates,» Alfaro said.
They promise new details
about evolutionary history, such as genome duplications and invasions by rogue DNA, and make it easier to find specific DNA involved in traits important for an organism's survival or for agricultural improvements.
And the marbled lungfish — a living piece of
evolutionary history with the largest genome of any animal — is also rated as of least concern, despite being commonly eaten by humans.
«The finding that in immature chimpanzees, like humans, object - oriented play is biased towards males may reflect a shared
evolutionary history for this trait dating back to our last common ancestor,» write the researchers from Cambridge, Zurich and Kyoto, who studied communities of wild chimpanzees and bonobos in Uganda and Congo for several months, cataloguing not just all tool use, but all object manipulation.
Often called the «Cambrian explosion,» fossils from this time provide glimpses into
evolutionary history as the world's ecosystems were rapidly diversifying.
By extensive phylogenetic analysis, we show here that SARM is closely related to bacterial proteins with TIR domains, suggesting that this family has a different
evolutionary history from other animal TIR - containing adaptors, possibly emerging via a lateral gene transfer from bacteria to animals.
«The fact is, hypotheses about whether sponges or comb jellies came first suggest entirely
different evolutionary histories for key animal organ systems like the nervous and the digestive systems.
«The combination of high climate - change velocity and multidimensional human fragmentation will present terrestrial ecosystems with an environment that is unprecedented in
recent evolutionary history.»
Confirmation of this latter hypothesis would have far - reaching implications for our understanding of
evolutionary history because comb jellies and their relatives are relatively complex animals — unlike sponges and placozoans, ctenophores possess muscles and a nervous system.
Rapid morphological change has occurred many times in
mammalian evolutionary history [44], with and without human intervention, including domestic dogs [45] and silver foxes (tamed from wild Russian red foxes (Vulpes vulpes)[46 — 48].
Furthermore, the endangered red and eastern wolves are not unique lineages with
distinct evolutionary histories, but relatively recent hybrids of gray wolves and coyotes, the scientists report online this week in Science Advances.
But once the researchers began looking for traces of similar yeasts in other lichens, they found related lineages in 52 genera of lichens worldwide and molecular evidence that indicates a long, shared
evolutionary history between the symbiotic partners.
Together, the amber feathers encompass the
entire evolutionary history of feathers in four different stages, from simple filaments to flight - capable plumes.
They placed the data from the 322 animal genomes into a «tree» to determine when in an animal's
evolutionary history did the CMAH gene became inactive or «turned off.»
Non-human taxa were chosen to match classical definitions of cursorial and non-cursorial
evolutionary history based on morphological adaptations to endurance running (Jenkins, 1971).

known evolutionary history between lice and primates, this makes an ideal system to study bacterial genome evolution» said Boyd.
In the Aug. 25 issue of the Proceedings of the National Academy of Sciences, the Yale scientists reported vast differences between organisms in terms of these fossils, reflecting the
divergent evolutionary histories of flies, worms, and humans.
By reconstructing enzymes as they might have looked billions of years ago, the research «helps to explain the
natural evolutionary history of life on this planet,» says Yousif Shamoo, a biochemist at Rice University in Houston who wasn't part of the study.
