The video descibes creation of complexity - complexity of universe[D1] and mostly complexity[D2] of life itself. The speaker pointed out that from the perspective of human being[D3] (one of the most complex objects in the universe) it is very important to understand how such complexity is born. The evolution of complexity is demonstrated on several thresholds troughout[D4] the history of universe. The first threshold is the moment universe was born – [D5] The Big Bang,[D6] throughout the video there are six more – ending with the modern revolution. Modern revolution was also marked as the main sign of collective learning which is privilege[D7] of humankind and the most important distinction between humans and other entities. The video should probably serve [D8] as a warning against abuse[D9] of collective learning and knowledge. Good job, good vocabulary. Would advise to use more linkers to connect your ideas in general. ________________________________ [D1]the universe [D2]the [D3]beings or a human being [D4]typo [D5]I do not think this way of implementing information in the middle works here, as Big Bang clearly connects as the first threshold, while the statement there are six more does not seem to connect to the previous [D6]I would end the sentence here and start a new one, or use some linker – and then throughout … [D7]A privilege [D8]Avoid should, do not imply here, and together with probably it is too vague too – The video’s intention is to warn [D9]the abuse
