Effect of Study Habits on Academic Performance of High School Students
a.VOCABULARY
Prehistory can refer to the period of human existence before the availability of those written records with which recorded history begins.
Fossils are the preserved remains or traces of animals (also known as zoolites), plants, and other organisms from the remote past. artifact or artefact is "something made or given shape by man, such as a tool or a work of art, esp an object of archaeological interest".
A nomad is a member of a community of people who move from one place to another, either with their livestock (pastoral nomads) or subsisting on hunting and gathering.
b. Kinds of evidence that archeologist and anthropologists look for to find out how people lived before written records were kept.
Paleontology provided some of the first evidence for evolution at the beginning of the 19th century, when it was noted that fossils occurred in a sequential order in layers of rock. Simpler organisms occurred in lower layers, while more modern-appearing ones were always found closer to the top. Because bottom layers of rock are older than top layers, the sequence of fossils is a chronology from oldest to youngest. Thousands of rock deposits have been identified that show corresponding successions of fossil organisms; as you move from newer to older rocks, life is less like modern living things. Species found in older layers are always simpler and species in newer layers more modern.
Comparative Anatomy Structures that share an embryological origin (through common descent) - even if they function in different ways - are known as homologies. Evolutionary theory predicts that species that evolved from other species should have homologous structures. This is because the original structures are modified and serve a different purpose.
Biogeography - geographic patterns of species distribution Evolutionary theory predicts that groups of organisms that are evolutionarily related will also be geographically connected, if not in the present then at least at
