Transitional armour describes the armour used in Europe around the 13th and 14th centuries, as body armour moved from simple mail hauberks to full plate armour. The couter was added to the hauberk to better protect the elbows, and splinted armour and the coat of plates provided increased protection for other areas. Armourers in general began ...

Evidence of evolution. All modern birds are descended from a group of dinosaurs called theropods. Theropods first appear in the fossil record during the late Triassic to early Jurassic period, roughly 200 million years ago. In contrast, fossils of taxa similar to modern birds can be found in the fossil record by the end of the Cretaceous period ...

Evidence for large-scale evolution ( macroevolution) comes from anatomy and embryology, molecular biology, biogeography, and fossils. Similar anatomy found in different species may be homologous (shared due to ancestry) or analogous (shared due to similar selective pressures). Molecular similarities provide evidence for the shared ancestry of life.
