Scientists say that communications between fungi appear to resemble human speech. 

Researchers in the UK have studied fungi communication, and found patterns of electrical activity that could resemble human speech. 

The team found spikes in the electrical potential of four species of fungi, and found these spikes are often clustered into 'trains of activity' which indicate information being communicated between distant parts of the fungal colonies. 

The spikes appear to resemble vocabularies of up to 50 words. 

Fungal 'word length' (spike groups of 5.97) averaged the same as some human languages, for example 4.8 in English and 6 in Russian.
