The use of the term for the Iranian language family was introduced in 1836 by Christian Lassen. Robert Needham Cust used the term Irano-Aryan in 1878, and Orientalists such as George Abraham Grierson and Max Müller contrasted Irano-Aryan (Iranian) and Indo-Aryan (Indic). Some recent scholarship, primarily in German, has revived this convention.

Ah, so.. Christian Lassen

The latest study using magnetic resonance imaging (MRI) to humans and dogs together proved that dogs have same response to voices and use the same parts of the brain as humans to do so. This gives dogs the ability to recognize emotional human sounds, making them friendly social pets to humans.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Because dogs respond to voices the same way humans do, they are able to recognize what in human sounds, making them social?
Ah, so.. emotion

The development of a three-field rotation system for planting crops[AA] increased the usage of land from one half in use each year under the old two-field system to two-thirds under the new system, with a consequent increase in production. The development of the heavy plough allowed heavier soils to be farmed more efficiently, aided by the spread of the horse collar, which led to the use of draught horses in place of oxen. Horses are faster than oxen and require less pasture, factors that aided the implementation of the three-field system.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What invention led to an increase in efficiency in the farming of heavy soils?
Ah, so..
the heavy plough
