Mutations disprove the theory of upward evolution

[TheBeardedDude]

Just to preemptively shutdown what point you think you might be trying to make, stasis in the biological world means a group experiences little to no change over long stretches of geologic time because they are adapted well enough to their environment and selection pressures are low enough and population high enough, that change does not occur.

There are no selection pressures on some of the most primitive organisms because they live in areas where competition is low and resources are high.
