History of communication on wiki says Human communication was revolutionized with speech about 200,000 years ago. Symbols were developed about 30,000 years ago, and writing about 7,000 man!! isn’t that astonishing, well i see it the other way round. When we say human communication does it mean speech or literature? If this is true, then does it mean that animals don’t communicate!!! If even if they do in there own ways do they follow there own language? And in such case do we have any explanation on communication between plants? No wonder they do communicate. Plant roots communicate in parallel with rhizobia bacteria, with fungi and with insects in the soil. More information available here
Was thrilled when writing this post....with all this in mind, how do we define life? On this will scribble next time.
