TomA << Adam and Eve were real people as described in the book of Genesis. >>
Okay, now the harder question is when would they have lived, and please square that with the anthropological evidence and strong scientific case for human evolution.
Oh sure that neatly takes care of all the theological objections, and that’s how a lot of people handle it, but not me. I take the harder route accepting modern science.

The fundamental crux of the problem is this: 1) and 2)
- Catholics must believe that a First Man and a First Woman existed. All human beings alive today find their origin in these “first two” and only these “first two”.
- Ernst Mayr says “Evolution is change in properties of populations of organisms over time”. In other words, the population is the so-called unit of evolution. Genes, individuals and species also play a role, but it is the change in the popultation that characterizes organic evolution."
How can there be a “first” of a species when there only is a "slow, statistically sporadic altering morph called a “population”. One cannot make a species/species distinction.
Thus I think it can be overcome this way:
A) Individuals make up a population.
B) Individuals are the OBJECT of selection.
C) Yet a population is the UNIT OF MEASURE for evolution.
D) Population corresponds to a “sampling measurement” of evolution.
E) Individual corresponds to the ‘organic object’ that is selected.
THUS the Population IS NOT the ‘organic object’ that is selected.
Maybe it can be squared like this.
The error occurs in philosophy and evolution when the individual is made as the “unit of evolution”. This error is seen in people like Dawkins who criticizes Pope John Paul II’s statement: “Consequently, theories of evolution which, in accordance with the philosophies inspiring them, consider mind as emerging from the forces of living matter or as a mere epiphenomenon of this matter, are incompatible with the truth about man.” This relates to subjectivism, mind, thought, and consciousness in evolutionary history. G.K Chesterton also addressed this aspect in the first part of “The Everlasting Man”.
OR
When evolution treats the “unit of evolution”, the population, AS an individual (particularizing a population). This relates to a destroying of the distinction between a population as fluid and made up of individuals and not AS a closed system, IE. an individual.
Related to this second error is the need for a further clarification as to what a population is:
“A population is a group of organisms of the same species occupying a particular space at the same time…Populations have a birth rate and an immigration rate that add to the population and a death rate and an emigration rate that shrinks a population” pg. 161.
AND
"Few species populations are continuous. Such seperations of populations interconnected by immigration are called metapopulations."pg. 163 (Both quotes from "Ecology and Field Biology 6th ed. Smith and Smith.)
Yet as already demonstrated somewhat an individual is NOT the unit of evolution) THUS if this is done…the measurement of evolution is broken down.
One can then see that a populational view in itself of evolutionary change doesn’t conflict with the apparant
individual first true “Homo sapiens” parents.
THEN…one more question thus arises surrounding the issue of evolutionary populations and Adam and Eve. You believe the fact that other individual very-‘like’-man species of hominids of the population Adam and Eve rose from do not exist today.
There are two solutions to this: There is the population-bottleneck solution, and the “genetic contribution solution”. The population-bottleneck solution would require the fact that
every hominid in the population either became extinct or that the “Adam & Eve” left the population. Either way there can “only be two”. There is evidence for a massive bottleneck occuring in Africa to the Homo sapiens population in the genetic record. Yet there are two things I am not comfortable with here. A) “Adam & Eve” should not be hung onto any scientific theory, and B) A bottleneck down to two people doesn’t seem realistic and subsequent long term total population isolation of the first two humans and their progeny.
