Advances in the free game C-evo are similar to the advances in Civ1 and Civ2 (in later games called "techs"), but with significant differences. The on-screen Manual divides advances into four groups, based roughly on chronology, i.e. related to the key stages in which they become available.
With a few exceptions, each advance can be researched only after you have researched the two others specified for it, unless you get a start from another nation (by negotiation - or if you have the Temple of Zeus active then by conquest) or the Great Library.

Available from the startEdit
- Bronze Working
- Ceremonial Burial
- Horseback Riding
- Warrior Code
- The Wheel - almost certainly the one you should start with
Others dependent on earlier advancesEdit
There are 29 others listed in the first group in the manual; each requires the prior discovery of one or two other specified advances. Most of the names will be familiar to players of "Civ" games, but there are significant differences to watch.
When invited to select an advance, you have the option to "Focus" on one of the 29 that is not currently available. You are then presented with a menu that includes only the advance(s) necessary to reach your goal.
"Industrial Age Advances"Edit

Every one of the next group except Science has Science, a "Key Technology", as one of its prerequisites (directly or indirectly).
Science itself has three prerequisites - Metallurgy, Philosophy, and Theology, but only two are required. The discovery of Science makes a number of additional bonus tiles visible and usable. They include bauxite, coal, manganese, oil, and diamonds.
The science-dependent advances number 32. You may focus on any one of them that isn't visible, as for the earlier group.

Discovering Mass Production lets you see which of the apparently dead lands actually conceal rare minerals vital for winning the game.
In addition to Mass Production, there are 19 "Modern Advances".
- See also: Template:C-evo future
There are four sets of advances classed as "Future Technologies". Each can be researched in 25 or more stages, each stage taking four times as long as a normal advance. Each adds a percentage to something, such as weapon strength or city productivity. You cannot get them from another nation or the Great Library.
Focus at higher ldevelsEdit
Both the Modern and the Future advances may be the subject of a focus as soon as you have Mass Production.
