based on the logic of the statement we could have more senses if we could have more specialized organs and also it doesn t say if only one organ could be associated with more special senses:) we could find out more complex senses that helps us understand and integrate ourselves in the world by exploring the already known specialized organs .Maybe we have so many hidden senses that they blend so well we can t even find them:))
Maybe your question was yes or no. i think it needs more context to it to know how to answer to it.
