Photosynthetic bacteria has evolved. Symbiotic living has turned it into chloroplasts
They arose from a symbiotic union of two organisms.
Chloroplasts and mitochondria are believed to have originated from a process called endosymbiosis, where a eukaryotic cell engulfed a photosynthetic bacterium (for chloroplasts) and a respiratory bacterium (for mitochondria). Over time, these bacteria developed a symbiotic relationship with the host cell, eventually evolving into the organelles we see today. This process provided the host cell with energetic advantages, leading to their evolutionary success.
Mitochondria are believed to have evolved from ancient bacteria that were engulfed by primitive eukaryotic cells. This symbiotic relationship allowed the host cell to harness the energy produced by the bacteria through aerobic respiration, leading to the development of mitochondria as specialized organelles. Over time, mitochondria have evolved in structure and function to become essential for cellular energy production.
They evolve from prostganglionic neurons of the sympathetic fibre.
No, all life evolves. Bacteria evolve, viruses evolve, protists evolve, plants evolve, fungi evolve and animals evolve. Evolution is driven by Natural Selection. So, no. The evolution of all life on Earth is driven by Natural Selection: all bacteria, plants, animals, mammals, fish, insects, biochemical pathways, behaviours et cetera evolve by Natural Selection.

Lombre can evolve at any level because it doesn't evolve according to level, you need to use a Water Stone in order to evolve.
Stunky evolves according to level and it will evolve at Level 34.
Lucario doesn't evolve according to level because it's not capable of evolving.
Ursaring doesn't evolve according to level because Ursaring is not capable of evolving.
Skitty is capable of evolving at any level because it does not evolve according to level, you have to use a Moon Stone on it in order to evolve it into Delcatty.
Poliwag evolves according to level, it will attempt to evolve once it's at Level 25.
scales
According to Bulbapedia.com its level 35
The Pokémon that evolve according to gender are male Burmy which evolve into Mothim, female Burmy which evolve into Wormadam, female Combee which evolve into Vespiquen, female Snorunt which evolve into Froslass and male Kirlia which evolve into Gallade.
Koffing evolves according to level, it will start its attempt to evolve once it reaches Level 35.
Well, you can only evolve it if you trade it to someone else and as long as its over level 30. WRONG!!! You actually evolve it by leveling it to level 40 (according to www.serebii.net).
