What did Georges Cuvier discover?

Prior to Cuvier's work on extinction, scientists disagreed on whether fossils are the remains of still extant organisms or are from species types that no longer exist. Cuvier catalogued the divergent features of different types of elephants to show the variation between the Asian and African members of the species. He then demonstrated that both elephant species differed from discovered fossils to determine that the woolly mammoth had once existed as a separate and distinct organism.

What is the ship that Vasco Nunez de Balboa sailed on?

The Spanish expedition Balboa joined in 1501 gathered treasure, but the two ships were sunk in 1503 due to the damage previously caused by teredo worms. The ships were too damaged and could not survive the storm, so they sunk, and part of the treasure they had gathered was lost. During a later expedition, Balboa sailed on a boat called the Rolling Wind, but the year of that expedition is uncertain.

Who invented matches?

In 1829, Samuel Jones began making matches that were tipped with white phosphorus and sulfur. These matches were able to light after being struck on any surface. However, they produced a poisonous vapor that required a warning label on the box. A safer version of Samuel Jones' match was created in 1845 by J.E. Lundstrum, who used non-poisonous red phosphorus instead of white. Finally, the book-style matches still in use today were invented in 1892 by Joshua Pusey, whose patent was purchased and put into production by the Diamond Match Company.

Who built the pyramids?

In the past, widespread belief was that the Egyptians used slave labor to build the pyramids. Later archaeological evidence suggests that the pyramids were constructed by a special class of people who were housed, fed and organized into rotating teams. Evidence also suggests that fewer people were needed to build the pyramids than originally thought. By wetting down the sand in front of the stones, workers could manipulate heavy loads much more easily.

What was the debate between Patriots and Loyalists?

The Patriots' desire for freedom had a number of sources. The ideals of the Enlightenment, for example, which valued the individual and called-for governments based on rights and the consent of the governed, fueled the drive for revolution. Also, many merchants believed that they could thrive without British trade constraints. Loyalists also had complex motivations. Many wealthy Loyalists had established trade networks within the colonial system. Others, such as the Native Americans, believed that a free American government would trample on their rights. Still others favored an orderly tr..

What types of things did Native Americans use buffalo for?

When a buffalo was killed, Native Americans cooked and ate the best meat fresh, including the rump, ribs, tongue and other organs.

Buffalo bones were carved into clubs, knives and arrowheads, and horns were carved into s..
