Average members of a race/species will have stat bonuses of zero (prior to racial mods).
One of the quirks of Rolemaster is that the stats are not used to compare the stats of one race against another, but only within a race. 100 is the best a race can do, while 1 is the worst.
However, there are stats available to one degree or another...
Creatures have an IQ listed - that gives you an idea of its intelligence (reasoning, memory, intuition), especially when using table 2-13 on RMC C&T page 18. (this basically gives a number equivalent to human norms - no racial mods needed).
Then you also have the MS/AQ stats for monsters The Speed table on page 10 can help you for AG and Quickness. Treat MS Base column as their Agility Bonus, and the AQ Initiative Modifier column as its Quickness bonus.
Hope that these suggestions help..
