Whether that's creating new Alexa capabilities with the Alexa Skills Kit (ASK), building devices that use Alexa for new and novel voice experiences using the Alexa Voice Service (AVS), or something else entirely, if you have a visionary idea, we'd love to talk to you.
The definition of 'proximity' is 'the state of being near, next, or close'. 'Distance' or 'remoteness' are antonyms of 'proximity'. Using 'close', while redundant, is reinforcing the rarer word. Just because people do it often doesn't mean it makes sense; those people 'could care less'.
The fundamental biostratigraphic unit is the biozone. The range zone is defined by the geologic range (the total time of existence) of a particular fossil group or species. For example the range zone of the fossil graptolites is Ordivician to Devonian. A concurrent range zone is the overlapping range zones of two or more fossils with different geologic ranges.
