What does "potentially humans" mean? Like the fact that we are here in retrospect means that our microbe ancestors were potentially human?
My own understanding is "potentially human" is that we always had the potential to be human, which means that we have a rational soul, which differentiates humans from the animal species from which we evolved. Somewhere along the line of evolution, humans were instilled by God with a rational soul and that is when they became human.
As I said to Christiane, the Baha'i view of evolution is complicated and since I am not proficient in scientific subjects I try to stay away from discussing it. Below is a synopsis, but more is written elsewhere.
Evolution
In regards to
evolution and the origin of man,
`Abdu'l-Bahá gave extensive comments on the subject when he addressed western audiences in the beginning of the 20th century. Transcripts of these talks can be found in
Some Answered Questions,
Paris Talks and the
Promulgation of Universal Peace. `Abdu'l-Bahá describes the human species as evolving from a primitive form to modern man, but that the capacity to form human intelligence was always in existence.[

`Abdu'l-Bahá's comments seem to differ from the standard evolutionary picture of human development, where
Homo sapiens as one species along with the great apes
evolved from a common ancestor living in Africa millions of years ago.
While `Abdu'l-Bahá states that man progressed through many stages before reaching this present form, `Abdu'l-Bahá states that humans are a distinct species, and not an
animal, and that in every stage of evolution through which humans progressed, they were
potentially humans.
But at all times, even when the embryo resembled a worm, it was human in potentiality and character, not animal. The forms assumed by the human embryo in its successive changes do not prove that it is animal in its essential character. Throughout this progression there has been transference of type, a conservation of species or kind. Realizing this we may acknowledge the fact that at one time man was an inmate of the sea, at another period an
invertebrate, then a
vertebrate and finally a human being standing erect. Though we admit these changes, we cannot say man is an animal. In each one of these stages are signs and evidences of his human existence and destination.

Mehanian and Friberg wrote a 2003 article describing their belief that `Abdu'l-Bahá's statements can be entirely reconciled with modern science. Mehanian and Friberg state that `Abdu'l-Bahá's departures from the conventional interpretation of evolution are likely due "to disagreements with the metaphysical, philosophical, and ideological aspects of those interpretations, not with scientific findings."
[5] And to this end `Abdu'l-Bahá suggested that a
missing link between human and apes would not be found.
[22] The idea of a missing link per se was abandoned by science in favor of the idea of evolutionary transitions.
[23][24]
There are some differences between `Abdu'l-Bahá's statements and current scientific thought. The Bahá’í perspective that religion must be in accordance with science seems to suggest that religion must accept current scientific knowledge as authoritative; but, according to Mehanian and Friberg, this is not necessarily always the case as in their view the present scientific point of view is not always correct, nor truth only limited to what science can explain.

Oskooi chose the subject of evolution and Bahá'í belief for his 2009 thesis, and in doing so reviewed other Bahá'í authors' works on the subject. He concluded that, "The problem of disharmony between scripture and science is rooted in an unwarranted misattribution of scriptural inerrancy."
[25] In other words, he believes that `Abdu'l-Bahá made statements about biology that were later proved wrong, and that `Abdu'l-Bahá's infallibility should not be applied to scientific matters.
Several authors have written on the subject of evolution and Bahá'í belief.
