* A 1990s OVA titled ''The E.Y.E.S. of Mars'' provides an interesting subversion by showing that life on Earth didn't originate from outer space, but ''human consciousness and sentience'' did. The last of Humanity (who migrated from the planet of Titan-- itself destroyed and now the asteroid belt) lived in a domed city built in a crater on the inhospitable Martian surface. Years of rising tension over the increasingly worse air and water quality and confined spaces finally resulted in everyone going to war and ultimately destroying the dome, collapsing the structure into itself and exposing everyone to the unbreathable atmosphere. As a last ditch effort, the superpowered main characters transferred everyone's souls into the developing ''Homo'' primates that were just learning to walk upright.
* Life on Earth was manipulated by the Creators/Advent/Uranus in ''Manga/{{Guyver}}'' as part of their goals to create a powerful bio-weapons platform. Humanity was the end result, a base form that could be adapted into specialised combatants like Zoanoids and Zoalords. The experiment was aborted near completion when they gave a base level human one of the bio-armour units that worn by the Creators themselves and it turned out not only far more powerful than expected but completely immune to their telepathic control.

* ''Series/DoctorWho'':
** The Time Lords were one of the earliest races to evolve, and they either seeded the universe with their genetic material or affected the fundamental properties of the universe itself, so it's not that Time Lords are humanoid, but humans are "Time Lord-oid".
** "[[Recap/DoctorWhoS17E2CityOfDeath City of Death]]" says that life on Earth was accidentally started by an exploding Jagaroth ship.
* In perhaps its biggest predictive stretch, an episode of ''Series/LifeAfterPeople'' proposes that this could happen to Europa, one of Jupiter's moons, which is believed to have water oceans. With no humans left to direct it, a deep-space probe crashes there and introduces Earth bacteria to these oceans, which gradually give rise to an entire complex aquatic biosphere.

* In ''Franchise/{{Halo}}'', the Forerunners believed that [[AbusivePrecursors the Precursors]], a hyper-advanced race originating outside of the Milky Way, were responsible for seeding lifeless planets and speeding up the evolutionary process on planets that already had life. This is confirmed in ''[[Literature/HaloSilentium Silentium]]'', ''Mythos'' and ''Warfleet''. The Precursors explored the universe for ''billions'' of years and seeded countless galaxies with the building blocks of life and sped up the evolutionary processes of certain species. It may actually go further than that as ''Silentium'' heavily implies that the Precursors didn't just create life throughout the universe but that they ''created the universe itself''.

** It's actually that most sentient life colonised most of the habitable planets in the Galaxy for so long, people aren't completely sure of its origins, but Coruscant is suspected to be the homeworld of most Humans, along with most other Humanoid deviations. Most Planets do seem to have their own native species on them, so it's not ''completely'' Panspermia.
