Hey Sandy,
The core gameplay of the game will stay the same, each event has 3 choices and they change the 5 values of the civilization or create signals, spaceships or colonies. Recently we also added status effects which will play a bigger role in the next update that is about synthetic lifeforms.
To the Dog domestication event ( in the next update each planet has also different "Dog" species so the wording of the event will change a bit ) the expansion option of a paradigm shift event is always gives a population boost but also increases resource consumption a lot, we try to convey this with this text
"Natural hunters and loyal protectors; the animals play a key role in establishing new settlements in dangerous territories on Earth. The creatures evolve into domesticated servants."
The "bad" decent option increases Harm Potential and decreases Ethics which we try to convey with this text
"The predatory animals are primarily seen as food; but are also tied to guard posts on the borders of settlements to ward off unwanted trespassers."
