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 ...
large-scale evolutionary changes that take place over long periods of time. Species is a group of populations whose members have the potential to produce fertile offspring. the existence of biological barriers that impede two species from producing viable, fertile offspring. the offspring of crosses between different species. (sperm and egg ...
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 ...

A coat of plates is a form of segmented torso armour consisting of overlapping metal plates riveted inside a cloth or leather garment. The coat of plates is considered part of the era of transitional armour and was normally worn as part of a full knightly harness. The coat saw its introduction in Europe among the warring elite in the 1180s or ...
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.
- There are multiple possible explanations for those examples you cite. The fossils or their age could have been misidentified. It is also possible t...

- The identified age is counted as evidence for evolution. In the pictures showing the evolution of horses, there are dates shown. Why do you think t...
The AP ® Learning Objectives listed in the Curriculum Framework provide a transparent foundation for the AP ® Biology course, an inquiry-based laboratory experience, instructional activities, and AP ® exam questions. A learning objective merges required content with one or more of the seven science practices.
