The point isn't that there will be "evolutionary parallels", but that there will be Striking Similarities between Earth life and life on other planets (depending on how long it has existed there), simply because our universe is bound to the same laws, Everywhere.
Sure, the lifeforms will have different adaptations regarding temperature, gravity, day/night cycles, etc., but if a lifeform in another planet ends up reaching "human-level" intelligence or more, the "mental processes or logical conclusions" will be the same, again, depending on how much time it has had to evolve. Because "intelligence" is the trait by which the organism interacts with the universe and changes it. And since the universe is homogeneous, the "intelligent", alien organisms that evolve, will keep moving toward more and more similar forms.
