Cubone alng with its evolution of Marowak are in the same Monster Egg Group along with Lickitung and its evolution of Lickilicky, Kangaskhan, Snorlax, Larvitar and its evolutions, Aron and its evolutions, Cranidos, Rampardos, Shieldon and its evolution of Bastiodon, Amaura, Aurorus, Bergmite, Avalugg, the Kanto Starters and their evolutions, Nidoran and its evolutions, Slowpoke and its evolutions, Rhyhorn and its evolutions, Lapras, Chikorita and its evolutions, Totodile and its evolutions, Mareep and its evolutions, Treecko and its evolutions, Mudip and Whismur and their evolutions, Tropius, Turtwig and Gible and their evolutions, Snover, Abomasnow, Axew and its evolutions, Druddigon, Helioptile, Heliolisk, Tyrunt and Tyrantrum.
Here's a list: Agility if bred with Pidgey, Fearow, Doduo (and their evolutions). Haze if bred with Ekans, Zubat, Murkrow (and their evolutions). Pursuit if bred with Spearow, Doduo, Murkrow, Wingull (and their evolutions). Rage if bred with Doduo (and evolutions).
It depends on the Pokemon. Most evolutionary forms will learn the same moves as their pre-evolutions, only at later levels, but some pre-evolutionary forms learn moves that their evolutions don't. This happens with some Pokemon that evolve by evolution stone, where their evolutions don't learn new moves.
A better question would be what Pokemon CAN'T you get. Just about all of them are obtainable, except for the following: The three Kanto starters and their evolutions Mewtwo Mew The three Johto starters and their evolutions Murkrow and Honchkrow Misdreavus and Mismagius The three Johto Legends (Entei, Raikou, Suicune) Lugia Ho-Oh Celebi The three Hoenn starters and their evolutions Trapinch and it's evolutions Clamperl and it's evolutions Latias and Latios The Weather Legendaries (Groudon, Kyogre, Rayquaza) Jirachi Deoxys Glameow and Purugly Stunky and Skuntank This leaves a grand total of 56 Pokemon that are unobtainable by normal means.
Aside from legendary Pokemon and starters from past generations, Murkrow and its evolutions, misdreavus and its evolutions, trapinch and its evolutions, clamperl and its evolutions, Glameow and its evolutions, and stunky and its evolutions cannot be found in the wild in Pokemon Platinum.
No Pokemon evolves into milktank. Milktank has no evolutions or pre-evolutions.
In Pokemon Diamond/Pearl, the first two Electric Pokemon you can find are Shinx (evolutions: Luxio, Luxray) and Pachirisu (no evolutions).
If you don't have an action replay, other games, wifi or the GTS the Pokemon you cannot get are: Bulbasaur and evolutions, Charmander and evolutions, Squirtle and evolutions, Mewtwo, Mew, Chikorita and evolutions, Cyndaquil and evolutions, Totodile and evolutions, Raikou, Entei, Suicune, Lugia, Ho-oh, Celebi, Treecko and evolutions, Torchic and evolutions, Mudkip and evolutions, Latias, Latios, Kyogre, Groudon, Rayquaza, Jirachi, Deoxys, Murkrow and evolutions, Misdreavus and evolutions, Trapinch and evolutions, Clamperl and evolutions, Glameow and evolutions, Stunky and evolutions, Darkrai, Shaymin, and Arceus
I have them in Heartgold
thunder Pokemon if it has evolutions
No, Smeargle does not have an evolution. It's a one-stage Pokemon, meaning it has no evolutions or pre-evolutions.
No, because it has younger evolutions. Gible and Gabite are younger evolutions.
no, all the Pokemon in black and white are new; there are no evolutions of old Pokemon...

yes because it is a legendary Pokemon and so has no evolutions
Almost all pokemon with evolutions can be bred. Legendaries can not though.
