EXAMINE OWN ABILITIES.
Can we use the brainpower of other creatures to aid in research? If so, can we somehow TRANSMIT RESEARCH from one organism to another?
Find out what 'RESEARCH' actually means - do the organisms we control RESEARCH separately, share RESEARCH when in physical contact, or somehow transmit RESEARCH over large distances, making us more of a hive-mind?
Find out what is needed to do RESEARCH. Time? Total kilograms of infected biomatter? # of humans infected?
Once we know what we are, what RESEARCH is, how we (as a collection of many cells in many different organisms) become AWARE of RESEARCH, and what is NEEDED for RESEARCH, we can make better decisions on what to do.
So: EXAMINE OWN ABILITIES
and FIND OUT WHAT 'RESEARCH' MEANS, REQUIRES, and INVOLVES.
