question:
From what era, once thought devoid of animal life, was evidence of grazer populations discovered?, Context: Some paleontologists suggest that animals appeared much earlier than the Cambrian explosion, possibly as early as 1 billion years ago. Trace fossils such as tracks and burrows found in the Tonian period indicate the presence of triploblastic worms, like metazoans, roughly as large (about 5 mm wide) and complex as earthworms. During the beginning of the Tonian period around 1 billion years ago, there was a decrease in Stromatolite diversity, which may indicate the appearance of grazing animals, since stromatolite diversity increased when grazing animals went extinct at the End Permian and End Ordovician extinction events, and decreased shortly after the grazer populations recovered. However the discovery that tracks very similar to these early trace fossils are produced today by the giant single-celled protist Gromia sphaerica casts doubt on their interpretation as evidence of early animal evolution.
answer:
the Tonian period

question:
What was Daulah's title?, Context: The Nawab of Bengal Siraj Ud Daulah, the de facto ruler of the Bengal province, opposed British attempts to use these permits. This led to the Battle of Plassey on 23 June 1757, in which the Bengal Army of the East India Company, led by Robert Clive, defeated the French-supported Nawab's forces. This was the first real political foothold with territorial implications that the British acquired in India. Clive was appointed by the company as its first 'Governor of Bengal' in 1757. This was combined with British victories over the French at Madras, Wandiwash and Pondichéry that, along with wider British successes during the Seven Years' War, reduced French influence in India. The British East India Company extended its control over the whole of Bengal. After the Battle of Buxar in 1764, the company acquired the rights of administration in Bengal from de jure Mughal Emperor Shah Alam II; this marked the beginning of its formal rule, which within the next century engulfed most of India. The East India Company monopolized the trade of Bengal. They introduced a land taxation system called the Permanent Settlement which introduced a feudal-like structure in Bengal, often with zamindars set in place.
answer:
Nawab of Bengal
