What you describe is what we see in Genesis 1 & Genesis 7 example Genesis 1:24: Then God said, “Let the earth bring forth the living creature according to its kind: cattle and creeping thing and beast of the earth, each according to its kind”; and it was so.

Man reproduce after his own kind, therefore from Adam, the first man and Eve, the first woman, came all the races we know today. Although we call it micro evolution or evolution within species – it’s God’s natural way of inbreeding. However, as in some animals eg livestock, man needed to narrow the scope of this mating between close relatives because they lead to what is called deleterious traits. This is why, now we do not mate with family members. We are all brothers and sisters, all came from Adam and Eve

The only reason, I personally would not use the word “evolution” is because the word has many, many meanings and implications and when we use the word we have to first give a definition of what kind of evolution we are speaking about, because the most common understanding of the word EVOLUTION is… “Darwinian Evolution” which promote changes from one specie to another, basically it promotes “speciation” a process whereby a single ancestral species splits into two or more “different” species. I totally do not believe that at all.

The definition of Theistic Evolution:
“Theistic evolution or evolutionary creation is a concept that asserts that classical religious teachings about God are compatible with the modern scientific understanding about biological evolution. In short, theistic evolutionists believe that there is a God, that God is the creator of the material universe and (by consequence) all life within, and that biological evolution is simply a natural process within that creation. Evolution, according to this view, is simply a tool that God employed to develop human life.” – Wiki

We have to be very, very careful as Christians not to try and mix evolution with the Biblical accounts of creation. God did not use evolution to create the heavens and the earth. God did however create different species, that went on to multiply and there can be seen today, variations within species of animals and plants. This is actually NOT evolution, just variations within species. As I have said before, evolution is an extreeeeemly loooong process that happens over millions and millions of years. The changes that occur, within species (even humans) happens very, very fast and we can see that happening around us, for example when two different dogs mate, they have a beautiful variety of offspring’s, this is done within a periods of months, not millions of years, the same process can be done with cattle and plants. It is not destructive to the specie and no mutation is involved, it is actually beneficial.

Evolution (organic evolution), on the other hand falls under Macroevolution, a study which focus on change that occurs at or above the level of species or population. Example, birds came from dinosaurs or man came from monkey. This is what we do not believe in, because it is not observable and there are many hoaxes surrounding the study and also there are scientific laws and studies that goes against this belief system.

And yes, as you say, “God created all creatures on the earth” – to multiply, each after it’s own kind – this is also observable.

11 And not only that, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received the reconciliation.
12 Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all sinned— 13 (For until the law sin was in the world, but sin is not imputed when there is no law. 14 Nevertheless death reigned from Adam to Moses, even over those who had not sinned according to the likeness of the transgression of Adam, who is a type of Him who was to come. 15 But the free gift is not like the offense. For if by the one man’s offense many died, much more the grace of God and the gift by the grace of the one Man, Jesus Christ, abounded to many. 16 And the gift is not like that which came through the one who sinned. For the judgment which came from one offense resulted in condemnation, but the free gift which came from many offenses resulted in justification.

If we look at verse 14 which says Nevertheless death reigned from Adam to Moses, even over those who had not sinned according to the likeness of the transgression of Adam, who is a type of Him who was to come.

It clearly point out that as Adam was the first born of creation, so also, Jesus will (was) the first born of the new creation.

Now that is a figurative description of Christ and Adam – Adam is describe as one “who is a type of Him who was to come”.
Adam was the one that sinned, Christ is the one that did not sin. By Adam came death but, through Christ, who also suffered because of our sin, came life for all who believe that He is the Son of God.

Your second pronouncement about Christ is right and is Biblically based in John 1:1-10

1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was in the beginning with God. 3 All things were made through Him, and without Him nothing was made that was made. 4 In Him was life, and the life was the light of men. 5 And the light shines in the darkness, and the darkness did not comprehend[a] it.
6 There was a man sent from God, whose name was John. 7 This man came for a witness, to bear witness of the Light, that all through him might believe. 8 He was not that Light, but was sent to bear witness of that Light. 9 That was the true Light which gives light to every man coming into the world.[b]
10 He was in the world, and the world was made through Him, and the world did not know Him.

This is another Biblically based doctrine:
basically the last verse (v10) explain the whole thing. So yes, we can agree on this.

10 He was in the world, and the world was made through Him, and the world did not know Him.
