On the Indian subcontinentthe Mughal Empire ruled most of India in the early 18th century. During this period, the Empire was marked by a highly centralized administration connecting the different regions. All the significant monuments of the Mughals, their most visible legacy, date to this period which was characterised by the expansion of Persian cultural influence in the Indian subcontinent, with brilliant literary, artistic, and architectural results.
Complex Brains for a Complex World Endocasts of Homo erectus left and Homo sapiens right illustrate rapid increase in brain size. As early humans faced new environmental challenges and evolved bigger bodies, they evolved larger and more complex brains.
Large, complex brains can process and store a lot of information.
That was a big advantage to early humans in their social interactions and encounters with unfamiliar habitats. The modern human brain is the largest and most complex of any living primate. Brain size increases slowly From 6—2 million years ago During this time period, early humans began to walk upright and make simple tools.
Brain size increased, but only slightly. Brain and body size increase From 2 million—, years ago During this time period early humans spread around the globe, encountering many new environments on different continents.
These challenges, along with an increase in body size, led to an increase in brain size. Brain size increases rapidly From ,—, years ago Human brain size evolved most rapidly during a time of dramatic climate change. Larger, more complex brains enabled early humans of this time period to interact with each other and with their surroundings in new and different ways.
As the environment became more unpredictable, bigger brains helped our ancestors survive. Why the sudden increase in brain size?
Graphs showing changes in climate and changes in braincase volume. Notice how much the fluctuations increased betweenandyears ago. To construct this graph, scientists studied fossils of tiny organisms found in ocean sediment cores. The bottom graph shows how brain size increased over the past 3 million years—especially betweenandyears ago.
A large brain capable of processing new information was a big advantage during times of dramatic climate change. To construct this graph, scientists measured the brain cavities of more than early human skulls.
Evidence of ancient brains Endocasts are replicas of the insides of early and modern human braincases. They represent the size and shape of the brains that once occupied the braincases. How are endocasts made?Origins blends ingredients from nature with advanced science to create high performance and natural skincare, bath & body and makeup products.

One of the most hotly debated issues in paleoanthropology (the study of human origins) focuses on the origins of modern humans, Homo sapiens. 9,10,3,6,13,15,14 Roughly , years ago, the Old World was occupied by a morphologically diverse group of hominids. In Africa and the Middle East there was Homo sapiens; in Asia, Homo erectus; and in Europe, Homo neanderthalensis.
