Please refrain from making unconstructive edits to Wikipedia, as you did at Neanderthal. Your edits appear to constitute vandalism and have been or will be undone. If you would like to experiment, please use the sandbox. Repeated vandalism can result in the loss of editing privileges. Thank you.--Mr Fink (talk) 23:17, 16 May 2016 (UTC)
