There were serious scientific objections to the process of natural selection as the key mechanism of evolution, including Karl von Nageli's insistence that a trivial characteristic with no adaptive advantage could not be developed by selection. Darwin conceded that these could be linked to adaptive characteristics. His estimate that the age of the Earth allowed gradual evolution was disputed by William Thomson (later awarded the title Lord Kelvin), who calculated that it had cooled in less than 100 million years. Darwin accepted blending inheritance, but Fleeming Jenkin calculated that as it mixed traits, natural selection could not accumulate useful traits. Darwin tried to meet these objections in the 5th edition. Mivart supported directed evolution, and compiled scientific and religious objections to natural selection. In response, Darwin made considerable changes to the sixth edition. The problems of the age of the Earth and heredity were only resolved in the 20th century.
What was Darwin's concession to Karl von Nagel's objections?
A: Darwin conceded that these could be linked to adaptive characteristics

All of the executions which have taken place since the 1936 hanging of Bethea in Owensboro have been conducted within a wall or enclosure. For example, Fred Adams was legally hanged in Kennett, Missouri, on April 2, 1937, within a 10-foot (3 m) wooden stockade. Roscoe "Red" Jackson was hanged within a stockade in Galena, Missouri, on May 26, 1937. Two Kentucky hangings were conducted after Galena in which numerous persons were present within a wooden stockade, that of John "Peter" Montjoy in Covington, Kentucky on December 17, 1937, and that of Harold Van Venison in Covington on June 3, 1938. An estimated 400 witnesses were present for the hanging of Lee Simpson in Ryegate, Montana, on December 30, 1939.

The term "Late Middle Ages" refers to one of the three periods of the Middle Ages, along with the Early Middle Ages and the High Middle Ages. Leonardo Bruni was the first historian to use tripartite periodization in his History of the Florentine People (1442). Flavio Biondo used a similar framework in Decades of History from the Deterioration of the Roman Empire (14391453). Tripartite periodization became standard after the German historian Christoph Cellarius published Universal History Divided into an Ancient, Medieval, and New Period (1683).
What isn't the name for the division of the periods of history introduced by Bruni?
A:
unanswerable
