First report of wound treatment by a wild animal using a pain-relieving plant
Even though there is evidence of certain self-medication behaviors in animals, so far it has never been known that animals treat their wounds with healing plants.

When two animals look the same, eat the same, behave the same way, and live in similar environments, one might expect that they belong to the same species.

A multi-institutional, international team of evolutionary biologists, genetics specialists and phylogenomicists has found evidence that bird species began diversifying long before the dinosaurs went extinct.
How did insect wings originate? This is a question that represents an unsolved mystery of insect evolution. Despite many years of research, it is still not entirely clear from which body structure insect wings actually evolved ...

A group of organisms is said to have common descent if they have a common ancestor. In modern biology, it is generally accepted that all living organisms on Earth are descended from a common ancestor or ancestral gene pool.
A theory of universal common descent via an evolutionary process was proposed by Charles Darwin in his book On the Origin of Species (1859), and later in The Descent of Man (1871). This theory is now generally accepted by biologists, and the last universal common ancestor (LUCA or LUA), that is, the most recent common ancestor of all currently living organisms, is believed to have appeared about 3.9 billion years ago. The theory of a common ancestor between all organisms is one of the principles of evolution, although for single cell organisms and viruses, single phylogeny is disputed (see: origin of life).
In his book The Ancestor's Tale, Richard Dawkins uses the word concestor as a substitute for "common ancestor." This new word is very gradually entering scientific parlance.
