"Updates" to language

It seems to me  there is a diagreement among native speakers themselves !I thinks it is greatly occasioned  by many  "English " s which are used nowedays , American, British, ..... I wonder why natives do not agree to use one  English only  while all the world  has chosen  to speak their  language !!!! By doing that they will be more united and remove the burden on others to learn more than one English . English language emerged from England and from there one should receive updates  (like an internet server) .

EDITED: I have moved this to linguistics, and given it a new title that more accurately reflects the current discussion.

Ah, but Ahmedali, languages are organic and constantly evolving.  It's not at all like getting updates on an internet server - it would be more like saying that the only real cedar trees come from Lebanon, and only their seeds should be sent out across the world! 

Is there a similar case in your own language?  Does your language share common ancestry with the languages from other countries in your region? 

What do you see as the difference between evolving and being flexible?

People do not speak a certain way, then get an e-mail and learn that "different from" is now "differnt than," and immediately being using only the new usuage. It happens on its own.

If Kurdish is from Persian, how does it compare to the modern language or Persia/Iran?

Thank you  Grammar Geek for that effort  . I have posted a reply oblivious to the fact that I had not signed in , so it might be displyed anonymously and take  a longer time. I tried to explain that why changing the climate and Geogrphical location caused variety in the way peoples expressed themselves . It all has an intimate relation with the way new natural  enviroments  from soil ,  air , to water in that region affect the mood and subconscious  of that nation .What I have from my personal observation on my language as an example is that when a new word is imported to the languge , I find it is modified by all seperate groups of my people( even without having a direct contact) apprximately in the same way. It means that that nation has evolved a mechanism which is unseen to our eyes , by which new things are modified subconsciously.

Again sorry  if there  are  errors in my English , but i hope  Ihave imparted my point clearly.

Just today, someone posted for a Spanish-English dictionary, specifying "South American." I wish I knew Spanish so I could explore how Spain's Spanish is different from Peru's Spanish.

And Kooyeen, I laughed out loud. I already have "aubergine" because we use it as a color. Perhaps we should get "lorry." My daughter had to ask me about that one this week.
