User blog comment:Shadow Archon/Hypothesis: Explaining away the Zerus Discrepancy/@comment-58609-20150513060559/@comment-26354460-20150513065856

-The main thing about the life on Zerus is that all life on the planet is now Zerg. There's no life-form on the planet that is stated to be non-Zerg.

You have evidence of Zerg micro-organisms from the spawning pool and the Spore Ray. You have plant Zerg from the Zerusian Needle. You have the different packs of reptilian/insectoid Zerg vying for dominance, while also have herds of Quillgore Zerg seemingly not sapient enough to be part of any tribes themselves.

This all but outright states that all the life-forms on the planet are Zerg in some form.

As such, Stetmann's "More than 100,000 years of human evolution in one hour within a single life-form" can be applied to all life on the planet.

You're talking about life-forms that can surpass Earth's entire evolutionary history in three to four years...

Of course, beyond the speculation, an actual official explanation would have been appreciated.

-I never really considered the travel time to Zerus an issue. Chris Metzen stated that the UED completely used technology relatively equivalent to the Koprulu sector and left behind their advanced tech at home.

That means the DSS Aleksander, which looks exactly like any other Behemoth Class and did make the trip from Earth to the Koprulu Sector within the time-span of weeks at most, did so without their advanced tech.

Not to mention, the fleet was given a head start by Kerrigan to flee at the end of Brood War, and her Swarm managed to run the fleet down and destroy it completely, preventing any from getting back home.

As such, the FTL of modern StarCraft has been that fast since Brood War. It was no surprise at all for me to see her to make it to Zerus within a short time-span.

-The main issue I have with Zerus in relation to distance is the small communication device Arcturus uses to speak to Kerrigan on Zerus from Korhal.

If he can have an instant communique with Kerrigan half the galaxy away, why can't the Protoss on Kaldir send a message to Shakuras when they are both in the same sector of space in a much easier fashion than the Terrans apparently can?

-I do think the writers handled the issues poorly without fully explaining the apparent continuity issues. While I do really enjoy going to Zerus in the game and having a unique addition to the Zerg as a whole, I think they could have executed it much better.

Hopefully we don't get the same issues in LotV with the exploration of the history of the Protoss Purifiers and the Tal'Darim.
