Unit 10 lesson 7: the muslim world and africa unit test. 10) which mathematical innovation did the early muslim caliphates achieve a) astrolabe improvements b)urge to investigations to determine bias c)hindu-arabic numerals d)use of arches

The mathematical innovation achieved by the early caliphate is Hindu-Arabic numerals. This implies the correct answer is C.

Hindu Numerals are 10 symbols (1 2 3 4 5 7 9 0). This set of 10 symbols makes up the decimal number system.

These 10 sets of symbols emanated from India during the 17th century. They were also introduced to Europe through the writings of al-Khwarizmi and al-Kindi, who are both prominent Muslim mathematicians in the 12th century.

Also, one of the mathematical innovations achieved by the early Muslims caliphate is algebra. Algebra was developed by Al-Khwarizmi, who was one of the prominent Muslim mathematicians.

Al-Khwarizmi introduced the study of algebra and wrote many books on mathematics. He composed a book during the 1800s and was later interpreted into Latin. The book became a mathematics textbook that was put to use across Europe.

Al-Khwārizmī, also known as Muḥammad ibn Mūsā al-Khwārizmī was born 780. He was a great mathematician and astronomer. He contributed greatly to mathematics, particularly the development of algebraic and algorithm.

Al-Khwārizmī is widely regarded as the father of computer science and one of the prominent mathematicians of the Bayt al-Hikma.

Therefore, the mathematical innovation achieved by the early caliphate is Hindu-Arabic numerals. This implies the correct answer

early human migrations are the earliest migrations and expansions of archaic and modern humans across continents and are believed to have begun approximately 2 million years ago with the out of africa migration of homo erectus. this initial migration was followed by other archaic humans including h. heidelbergensis, which lived around 500,000 years ago and was the likely ancestor of both denisovans and neanderthals. early hominids were said to have "crossed land bridges that were eventually covered in water" .

within africa, homo sapiens dispersed around the time of its speciation, roughly 300,000 years ago.the "recent african origin" paradigm suggests that the anatomically modern humans outside of africa descend from a population of homo sapiens migrating from east africa roughly 70,000 years ago and spreading along the southern coast of asia and to oceania before 50,000 years ago. modern humans spread across europe about 40,000 years ago.

the migrating modern human populations are known to have interbred with local varieties of archaic humans, so that contemporary human populations are descended in small part (below 10% contribution) from regional varieties of archaic humans.

after the last glacial maximum, north eurasian populations migrated to the americas about 20,000 years ago. northern eurasia was peopled after 12,000 years ago, in the beginning holocene. arctic canada and greenland were reached by the paleo-eskimo expansion around 4,000 years ago. finally, polynesia was peopled after 2,000 years ago, by the austronesian expansion.
