PrimalMinister Posted March 6, 2019 Share Posted March 6, 2019 Given that we have an environment with water, land and air, wasn't it inevitable we ended up with things swimming in water, walking on land and flying in the air? For example, evolution might produce random 'wing' designs but only the ones that are areodynamic will work, meaning wings have a certain inevitability.

Land air and water need to have the correct ingredients/chemicals/composition for life to develop . And many factors can inhibit or block the development/evolution of life. Mars used to have a more dense atmosphere and it might have had life but when the magnetic field of Mars got destroyed, the atmosphere got thinner and probably destroyed life. In 2020 Nasa sends a rover that will steal rocks….'we' can then analyse those rocks to see if there was life.

As long as a mechanism for evolution exists: some form of heritability of characteristics, variation in the population, source of new variation, etc. Link to comment Share on other sites More sharing options...
MonDie Posted March 10, 2019 Share Posted March 10, 2019 Probability depends on the perspective. If determinism is true, life always had a 100% chance.

Language is a map of internal map of the external world. Our concepts are within, but they come from without. If an instantiation of some concept, e.g. the wing concept, has to meet functional criteria, e.g. allowing aerodynamic flight, then the notion of a non-functional, never-functional wing is absurd. Maybe you can clarify? Link to comment Share on other sites More sharing options...

The first living cell was a true miracle. A miracle that included two very complex ingredients and one amazing ability: RNA, the mitochondrion and the ability to split into two identical entities. It baffles me to just think about it. Many theists think this is a sign of divine intervention, but it really is just crazy crazy luck! -1 Link to comment Share on other sites More sharing options...

It's more efficient than non-life at using and dissipating light as energy for work, so it seems inevitable given enough time. Link to comment Share on other sites More sharing options...

Well, consider the fact that most cells do not possess mitochondria, for starters. Link to comment Share on other sites More sharing options...

Oh my, I feel the same exact way, all life just frigging happened, period, with no help or intervention from a being that had any kind of process to make a plan with any desired outcome.

Manta rays and other free swimming rays evolved from flat blotten dwelling rays and evolution seldom results in new structures but it does act on old ones... A Manta ray can fly through the water very fast as can other free swimming rays. The shape of a Manta ray is quite aerodynamic, see delta wing jets...

In the denser medium of water, mantas "fly", albeit more like an airplane than a bird since they don't need to constantly flap their wings to move and remain "aloft". With that bit of ignorance dispelled, has your objection to the opening post changed? Link to comment Share on other sites More sharing options...

You are so very wrong, some sea birds do indeed fly underwater, penguins for one and even sea birds that fly in air use their wings the very same way under water. I've actually seen this personally while scuba diving but it's shown on many nature shaws as well. Edited June 21, 2019 by Moontanman Link to comment Share on other sites More sharing options...
