New Pokemon evolutions?

[Sanehouse]

Hey there. I'm interesting in seeing which First Generation Pokemon have had evolutions and/or Pre-Evolutions added to them in Generations II, III and IV, and I was wondering if you could tell me which ones have had their evolution lines altered in the three newest generations (For example, Steelix evolves from Onix, but Steelix isn't a Gen I Pokemon, Umbreon and Espeon evolve from Eevee, Tyrogue evolves into Hitmonchan, Hitmonlee or Hitmontop).

Thanks in advance.

Subomi > Roselia > Rozerido

 

[Snake Bandage]

Subomi > Roselia > Rozerido

None of them are Gen I Pokemon, and the OP specifically asked about Gen I Pokemon. =/

Would Porygon 2, who evolves from a Gen 1 getting a new evo count?

 

[Argy]

Yes.

Porygon -> Porygon2 -> PorygonZ

Obligatory 'pedia link.

Only things that don't inter-link are Gen I and Gen III. Every other generation gets new evos of previous ones and new prevos of previous ones. Generation III only did prevos of Gen II.

 

[TTEchidna]

Yes, most definitely. In fact, so far, it introduced the most of all besides Gen I. 151 + 100 + 135 + 107 = 493. 19 Johto Pokémon were related to the previous 151, two Hoenn Pokémon were related to the previous 251, and 29 Sinnoh Pokémon are related to the previous 386. 27 Kanto Pokémon are related to the 342 new ones released in the years since RBY.

Maybe I should put up some sort of evolution analysis. Someday.
