A falconer with a Harris's hawk (an avian dinosaur). Birds evolved from a group of theropod dinosaurs during the Jurassic period.Modern birds are cladistically and phylogenetically dinosaurs, [5] and humanity has thus coexisted with avian dinosaurs since the first humans appeared on Earth.
They first appeared in the fossil record around 66 million years ago, soon after the Cretaceous–Paleogene extinction event that eliminated about three-quarters of plant and animal species on Earth, including most dinosaurs. [25] [26] One of the last Plesiadapiformes is Carpolestes simpsoni, having grasping digits but not forward-facing eyes.
First blood-sucking insects (ceratopogonids), rudist bivalves, and cheilostome bryozoans. Archaeopteryx, a possible ancestor to the birds, appears in the fossil record, along with triconodontid and symmetrodont mammals. Diversity in stegosaurian and theropod dinosaurs. 131 Ma First pine trees. 140 Ma Orb-weaver spiders appear. 135 Ma Rise of ...
Cro-Magnons are well known for having painted or engraved geometric designs, hand stencils, plants, animals, and seemingly human/animal hybrid creatures on cave walls deep inside caves. Typically the same species are represented in caves which have such art, but the total number of species is quite numerous, and namely includes creatures such ...
The modern human Oase 2 skull (cast depicted), found in Peştera cu Oase, displays archaic traits due to possible hybridization with Neanderthals. [57] The early modern human Oase 1 mandible from Peștera cu Oase (Romania) of 34,000–36,000 14 C years BP presents a mosaic of modern, archaic, and possible Neanderthal features. [58]
The chimpanzee–human divergence likely took place during around 10 to 7 million years ago. [1] The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage.

A human–animal hybrid and animal–human hybrid is an organism that incorporates elements from both humans and non-human animals. Technically, in a human–animal hybrid , each cell has both human and non-human genetic material.
