Barbarian observes:
There is abundant evidence for speciation
If there’s evidence,show it.
Sure. Some rare cases happen so rapidly that we can see it in a human life time, like the evolution of O. gigas from O. lamarckania.
Gradual speciation is harder to document, because it’s difficult to show precisely when the change took place in a very gradual process. The apple maggot fly didn’t exist when Europeans came to America, because there were no apples here. There was the hawthorn maggot fly, however, that lived on hawthorns, a relative of apples. Not long after apple trees became established, some of the hawthorn flies were able to live on apple fruit. It was not an easy thing, because apples develop at a different time, and the reproductive cycle of hawthorne flies does not match the availability of apples.
Over time,some of them evolved a different reproductive timing to take advantage of apples. Now, because of the timing, they rarely interbreed in nature; hybridization is successful only about 5% of the time… They are an incipient species.
And then there are ring species:
A classic example of ring species is the Larus gulls circumpolar species “ring”. The range of these gulls forms a ring around the North Pole. lineages meet.
Wikipedia.
If several populations were to go extinct in the intermediate locations, then gene flow would end between the Herring gulls and the lesser Black-backed gulls, and they would become two individual species.
Barbarian observes:
No. Natural sciences are based on the assumption of Uniformitarianism, which says that the rules by which this universe works, have always been the same.
The natural sciences are based on naturalism – the belief that all natural phenomena can be accounted for by scientific laws.
That is called “uniformitarianism.” Naturalism is the idea that nature is all there is. Science does not make such a claim.
the laws of nature thousands of years ago can’t be tested.
We can, for example, see what happened during ancient volcanic eruptions, by the remains of lava flows and ash falls, and we can see that the laws of science worked the same way billions of years ago. We can observe the physics at work in ancient supernovae explosions the light from which is only now arriving here. And every time it’s checked, we get confirmation.
But if the laws of nature have always been the same,then scientists should not believe in macro-evolution,because speciation has never been observed to go beyond the level of species.
Turns out that the evolution of higher taxa is no different than speciation. As you learned, even many creationists admit that new genera and families evolve. And there’s no barrier to higher speciation.
And of course there’s the genetic data, which our Pope has cited as demonstrating common descent of all living things:
Since it has been demonstrated that all living organisms on earth are genetically related, it is virtually certain that all living organisms have descended from this first organism.
Barbarian observes:
But you may also take it as Catholic Doctors of the Church like St. Augustine took it, as being allegorical.
Augustine didn’t take it as being allegorical.
You’ve been misled about that, too…
"Seven days by our reckoning, after the model of the days of creation, make up a week. By the passage of such weeks time rolls on, and in these weeks one day is constituted by the course of the sun from its rising to its setting; but we must bear in mind that these days indeed recall the days of creation, but without in any way being really similar to them" (ibid., 4:27).
(The City of God 11:6 [A.D. 419]).
And the Church teaches:
**Fundamentalists often make it a test of Christian orthodoxy to believe that the world was created in six 24-hour days and that no other interpretations of Genesis 1 are possible. They claim that until recently this view of Genesis was the only acceptable one—indeed, the only one there was.
The writings of the Fathers, who were much closer than we are in time and culture to the original audience of Genesis, show that this was not the case. …
Catholics are at liberty to believe that creation took a few days or a much longer period, according to how they see the evidence, and subject to any future judgment of the Church (Pius XII’s 1950 encyclical Humani Generis 36–37). They need not be hostile to modern cosmology. The Catechism of the Catholic Church states, “[M]any scientific studies . . . have splendidly enriched our knowledge of the age and dimensions of the cosmos, the development of life forms, and the appearance of man. These studies invite us to even greater admiration for the greatness of the Creator” (CCC 283). Still, science has its limits (CCC 284, 2293–4). **

It doesn’t matter that scientists don’t make that claim. They do claim that the human body is a product of evolution.
Barbarian observes:
So does Pope Benedict XVI. That’s consistent with Catholic doctrine.
Well, let’s take a look…
Converging evidence from many studies in the physical and biological sciences furnishes mounting support for some theory of evolution to account for the development and diversification of life on earth, while controversy continues over the pace and mechanisms of evolution. While the story of human origins is complex and subject to revision, physical anthropology and molecular biology combine to make a convincing case for the origin of the human species in Africa about 150,000 years ago in a humanoid population of common genetic lineage. However it is to be explained, the decisive factor in human origins was a continually increasing brain size, culminating in that of homo sapiens. With the development of the human brain, the nature and rate of evolution were permanently altered: with the introduction of the uniquely human factors of consciousness, intentionality, freedom and creativity, biological evolution was recast as social and cultural evolution.

Yes, it is. Chapter 3, section 63
Barbarian observes:
Since the Church teaches that God does not have a physical body,
(Statement verifying this)
**
< 9. Two themes converge to shape the biblical perspective. In the first place, the whole of man is seen as created in the image of God. This perspective excludes interpretations which locate the imago Dei in one or another aspect of human nature (for example, his upright stature or his intellect) or in one of his qualities or functions (for example, his sexual nature or his domination of the earth). Avoiding both monism and dualism, the Bible presents a vision of the human being in which the spiritual is understood to be a dimension together with the physical, social and historical dimensions of man.
- The central dogmas of the Christian faith imply that the body is an intrinsic part of the human person and thus participates in his being created in the image of God. The Christian doctrine of creation utterly excludes a metaphysical or cosmic dualism since it teaches that everything in the universe, spiritual and material, was created by God and thus stems from the perfect Good. Within the framework of the doctrine of the incarnation, the body also appears as an intrinsic part of the person. The Gospel of John affirms that “the Word became flesh (sarx),” in order to stress, against Docetism, that Jesus had a real physical body and not a phantom-body. Furthermore, Jesus redeems us through every act he performs in his body. His Body which is given up for us and His Blood which is poured out for us mean the gift of his Person for our salvation. Christ’s work of redemption is carried on in the Church, his mystical body, and is made visible and tangible through the sacraments. The effects of the sacraments, though in themselves primarily spiritual, are accomplished by means of perceptible material signs, which can only be received in and through the body. This shows that not only man’s mind but also his body is redeemed. The body becomes a temple of the Holy Spirit. Finally, that the body belongs essentially to the human person is inherent to the doctrine of the resurrection of the body at the end of time, which implies that man exists in eternity as a complete physical and spiritual person. >**
Of course, if you use the incarnation as an example of God having a body, you simply reinforce the obvious fact that God has no body. Jesus has a body only by virtue of becoming wholly man. As He says, God is a spirit. And He said that spirits have no body.
**It must, however, be noticed that in the Bible locutions of this kind ascribe human characteristics to God only in a vague, indefinite way. He is never positively declared to have a body or a nature the same as man’s; and human defects and vices are never even figuratively attributed to Him. The metaphorical, symbolical character of this language is usually obvious. …The limitations of our conceptual capacity oblige us to represent God to ourselves in ideas that have been originally drawn from our knowledge of self and the objective world. The Scriptures themselves amply warn us against the mistake of interpreting their figurative language in too literal a sense. They teach that God is spiritual, omniscient, invisible, omnipresent, ineffable. Insistence upon the literal interpretation of the metaphorical led to the error of the Anthropomorphites. **
