You need to explain yourself better.
It has already been pointed out that you've used the word "trans-genesis" incorrectly.
So what do you mean by "one animal becoming another?" Do you mean a new species?
Here are some to tide you over:
New species have arisen in historical times. For example:
A new species of mosquito, the molestus form isolated in London's Underground, has speciated from Culex pipiens (Byrne and Nichols 1999; Nuttall 1998).
Helacyton gartleri is the HeLa cell culture, which evolved from a human cervical carcinoma in 1951. The culture grows indefinitely and has become widespread (Van Valen and Maiorana 1991).
A similar event appears to have happened with dogs relatively recently. Sticker's sarcoma, or canine transmissible venereal tumor, is caused by an organism genetically independent from its hosts but derived from a wolf or dog tumor (Zimmer 2006; Murgia et al. 2006).
Several new species of plants have arisen via polyploidy (when the chromosome count multiplies by two or more) (de Wet 1971). One example is Primula kewensis (Newton and Pellew 1929).
Incipient speciation, where two subspecies interbreed rarely or with only little success, is common. Here are just a few examples:
Rhagoletis pomonella, the apple maggot fly, is undergoing sympatric speciation. Its native host in North America is Hawthorn (Crataegus spp.), but in the mid-1800s, a new population formed on introduced domestic apples (Malus pumila). The two races are kept partially isolated by natural selection (Filchak et al. 2000).
The mosquito Anopheles gambiae shows incipient speciation between its populations in northwestern and southeastern Africa (Fanello et al. 2003; Lehmann et al. 2003).
Silverside fish show incipient speciation between marine and estuarine populations (Beheregaray and Sunnucks 2001).
Ring species show the process of speciation in action. In ring species, the species is distributed more or less in a line, such as around the base of a mountain range. Each population is able to breed with its neighboring population, but the populations at the two ends are not able to interbreed. (In a true ring species, those two end populations are adjacent to each other, completing the ring.) Examples of ring species are
the salamander Ensatina, with seven different subspecies on the west coast of the United States. They form a ring around California's central valley. At the south end, adjacent subspecies klauberi and eschscholtzi do not interbreed (Brown n.d.; Wake 1997).
greenish warblers (Phylloscopus trochiloides), around the Himalayas. Their behavioral and genetic characteristics change gradually, starting from central Siberia, extending around the Himalayas, and back again, so two forms of the songbird coexist but do not interbreed in that part of their range (Irwin et al. 2001; Whitehouse 2001; Irwin et al. 2005).
the deer mouse (Peromyces maniculatus), with over fifty subspecies in North America.
many species of birds, including Parus major and P. minor, Halcyon chloris, Zosterops, Lalage, Pernis, the Larus argentatus group, and Phylloscopus trochiloides (Mayr 1942, 182-183).
the American bee Hoplitis (Alcidamea) producta (Mayr 1963, 510).
the subterranean mole rat, Spalax ehrenbergi (Nevo 1999).
Evidence of speciation occurs in the form of organisms that exist only in environments that did not exist a few hundreds or thousands of years ago. For example:
In several Canadian lakes, which originated in the last 10,000 years following the last ice age, stickleback fish have diversified into separate species for shallow and deep water (Schilthuizen 2001, 146-151).
Cichlids in Lake Malawi and Lake Victoria have diversified into hundreds of species. Parts of Lake Malawi which originated in the nineteenth century have species indigenous to those parts (Schilthuizen 2001, 166-176).
A Mimulus species adapted for soils high in copper exists only on the tailings of a copper mine that did not exist before 1859 (Macnair 1989).
There is further evidence that speciation can be caused by infection with a symbiont. A Wolbachia bacterium infects and causes postmating reproductive isolation between the wasps Nasonia vitripennis and N. giraulti (Bordenstein and Werren 1997).

The flu virus mutates 4 times a year by modifying its own genetic structure, becoming a new strand of the flu (new virus).
It's not very different from Darwin's Mangroves. Or from simians.
Also, crickets in central Canada who have survived the insecticide-producing GMO corn in the early y2k have changed color. Becoming sand-colored instead of a light green. They are also 10% larger...
I would like for you to specify "environmental scientist", if you please. That's a little vague...
*********************
What you are asking is virtually impossible to accomplish.
At the moment, there is approximately 1.6 million species that have been labelled, while there is an estimated 3 to 100 million species currently on the surface.
If we only give 100 000 individuals per species, you would need to pinpoint one individual at one specific moment where a genetic abnormality is large enough to distinct the mother's species from the offspring's.
If you are looking for new sub-families of species (like dinosaurs turning into brids), that isn't done over night. It took about 100 million years to the subranch of dinosaurs from which the velociraptors (they were turkey-size) were from; to evolve into the Giant Predator birds of the Mesozoic (austrige-size and larger), who weren't exactly birds in their genetic structure yet, but they had the basic characteristics. And then it took another 60 million years to turn them into flying predator birds (turkey-size and smaller).
I could elaborate and talk about the genetic traces in fossilized bones and how to extract it and retrace a species' family tree. But since you're supposed to be a scientist, I'll simply ask you to do your homework instead...

150 years ago, we didn't know about bacteria. No clue. It wasn't understood until Louis Pasteur determined that germs caused disease.
You are asking the same questions that scientists ask. You have, however, asked this in the Religion & Spirituality section, where we are mostly humanities majors, not biologists or physicists. Would you come to R&S to find out what opus number was Mozart's 40th Symphony? I think not. You're asking us to play to our weakness. Quite frankly, you're being unfair.
So let me suggest two things:
1. If you are serious about wanting to know the current evidence-based understanding on the origins of the universe and on evolutionary theory, there are excellent descriptions found at http://www.talkorigins.org .
2. Consider that you are proposing (not so subtly) that anything that is not explained is a place for God to be discovered. This is commonly referred to in ontology as "the god of the gaps" theory. It typically assigns God to any blank space that science has not yet reached useful conclusions. Remember what I said about disease? Before bacteria were discovered, it was assumed God was punishing the ill, or that they were demon possessed, or some other supernatural phenomenon caused sickness. This is the same god of the gaps.
Science never assumes, and should never assume, anything is supernatural. The purpose of science is to discover through measured observation, testing, and repetition what natural causes lead to our natural world. If you impose a statement "God caused it," then this stops the search for knowledge, because God is ultimately unknowable. This is the reason that the "god of the gaps" theory is discounted among learned ontological academicians, and is ignored by science.

mammoth eventually to modern elephant?
i don;t know cause they say the 6 day creation is a literal of 6 days .
we know that modern elephant and mammoth didnt exist together , for there is no modern elephant when mammoth exist .
we also know that mammoth certainly exist more than 7 days without modern elephant. and since the 6 day creation is a literal of 6 days that the genesis website claim it to be , thus during the since mammoth exist more than 7 days without modern elephant , we can assume modern elephant wasnt created during the first 6 days.
-
dog didnt exist till human domesticated wolf too .
-
many birds are evolving slightly , i do not have their name but apparent they cant mate with their distant ancestor.
-
it is also believed that iguana both land and water iguana ( i think it's iguana , correct me if i am wrong about the name of this creature ) both evolve from their common ancestor , a iguana that have both the traits of land and water iguana and able to hunt in both terrains.
edit:
dude the main purpose of evolution is to adapt , not become a new being .
there could be some major evolution that appears to form new creature but since my knowledge in such area is weak , i cant say much .
there are however evidence that says some dinosaur become the nowaday bird we see , but i arent sure .
do note that it is accepted that a meteor could have struck earth ( with strong supporting evidence ) that wiped out the dinosaurs . if that happen , it would not be a surprise if it greatly affect earth atmostphere and causes remaining dinosaur to eventually evolved into a new being

There was something in my high school biology class....
I'm not an evolutionist per se, but there was a study where frogs were taken from one location and moved them to another. Within a couple of generations, the two sets of frogs were re-introduced and were unable to successfully reproduce. Unfortunately, however, I can't source the experiment. Maybe somebody else can.
BTW, Mammoths are not progenitors of elephants, and wolves can successfully reproduce viable offspring with domestic dogs (one of the requirements for species).

How about the dinosaur - bird bit, where those dinosaurs actually started sprouting feathers and such? Of course, there's always Lucy and the rest of the critters who supposedly became humans. I'm trying to think of some others tho. I'm not an environmental scientist, but I AM a deacon and a logician... ;)

Perhaps you shoud learn the meaning of the big words you are using cause you are not using the term at all correctly..
TRANSGENESIS
Integration into a living organism of a foreign gene that confers upon the organism a new property that it will transmit to its descendents.
Trans gene sis consists of introducing an exogenous gene - called a transgene - into a living organism so that the organism will exhibit a new property and transmit that property to its offspring. In animals, for the transgene to be passed to descendants, it must be integrated into the gametes . The new property of the animal comes from the protein coded for by the transgene.
Researchers create transgenic animals in the laboratory as a means to better understand how our bodies function (embryonic development, diseases, including genetic diseases , drug action, etc.). They also serve as testing ground for new therapeutic molecules and the ‘medicinal’ genes of gene therapy . Gene transfer techniques and the universality of the genetic code make it possible to produce in bacteria human proteins like insulin, which is difficult and costly to chemically synthesize. The production of human growth hormone using these techniques will help to avoid the transmission of disorders such as Creutzfeldt-Jacob disease from animals that, in the past, produced the hormone for human treatment.

the peppered moth is still a moth ...selective breeding of dogs and cats to change traits has been practiced for years ...jacob even did it with sheep and goats in the bible to produce speckeled or solid color animals....no new species .
new information refuting evolution
http://www.harunyahya.com/c_refutation_darwinism.php
you are exactly right ...there is no hard data ...the evolutionists are stumped every time by that one ...in fact some top scientists who studied ... and previously believed the 'theory' ...now say that evolution cannot even be classified as a theory ...and that it is all based on pure conjecture and speculation ...there have been many frauds revealed as well ...that are still in text books ...for instance...leaky's lucy was admitted to be a fraud constructed to capture research funding twenty years after the fact...but leaky is still hailed as a leader in the field.
piltdown man was a fraud.
one "link" was examined by a doctor and shown to be the skeleton of a man with rickets ... which deformed the skeleton.
Dr D.James kennedy (who recently went to be with the Lord) at coral ridge ministries in florida has a lot of related info on the web site http://www.coralridge.org/CRMresources.asp

Oh Great Environmental Scientist ..... may I ask if you are asking about transgenesis where something like genes for insect resistence being transfer into tomato plants to make it insect resistance or Macro Evolution where one species slowly become another species over time?
I am getting confused with your question.
--------
New animal from another animal like a mule from a horse?

"The only evidence I have seen presented well demonstrates adaptive evolution, but there has been no proof of one animal becoming another."
this seems contradictory. what are you looking for exactly? hopefully you're not looking for a cat giving birth to a dog. after hundreds of thousands of years of adaptive evolution in a lineage, what exactly is to prevent "one animal becoming another"?
observed instances of speciation (many plants, but some animals too):
