No, Kent. If that happened it would debunk evolution. Evolution is the accumulation of small changes. A dog doesn't suddenly turn into a cat. How do you not know this???? This is basic evolution 101.

Please post a paper which demonstrates your opinion.
Lamarckism (or Lamarckian inheritance) is the hypothesis that an organism can pass on characteristics that it has acquired through use or disuse during its lifetime to its offspring. It is also known as the inheritance of acquired characteristics or soft inheritance. It is inaccurately[1][2] named after the French biologist Jean-Baptiste Lamarck (1744–1829), who incorporated the action of soft inheritance into his evolutionary theories as a supplement to his concept of orthogenesis, a drive towards complexity.
The theory is cited in textbooks to contrast with Darwinism. This paints a false picture of the history of biology, as Lamarck did not originate the idea of soft inheritance, which was known from the classical era onwards, and it was not the primary focus of Lamarck's theory of evolution. Further, in On the Origin of Species (1859), Charles Darwin supported the idea of "use and disuse inheritance", though rejecting other aspects of Lamarck's theory. Many researchers from the 1860s onwards attempted to find evidence for the theory, but these have all been explained away either by other mechanisms such as genetic contamination, or as fraud.
Despite this, interest in Lamarckism has continued.
Later, Mendelian genetics supplanted the notion of inheritance of acquired traits, eventually leading to the development of the modern synthesis, and the general abandonment of the Lamarckism in biology.
Lamarck is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin's first book dealing with natural selection was published in 1859): If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring. He said that change is made by what the organisms want or need. For example, Lamarck believed that elephants all used to have short trunks. When there was no food or water that they could reach with their short trunks, they stretched their trunks to reach the water and branches, and their offspring inherited long trunks. Lamarck also said that body parts that are not being used, such as the human appendix and little toes are gradually disappearing. Eventually, people will be born without these parts. Lamarck also believed that evolution happens according to a predetermined plan and that the results have already been decided.

Cause all the other facts points to A. sediba being 100% ape.

Proof of evolution would require showing that an organism can change into another organism. But all experiments show that there are particular boundaries that cannot be crossed. For example, bacteria that were claimed to have evolved after exposure to an antibiotic actually returned to baseline expression once the antibiotic was removed:
"...a rapid emergence of resistance and fast reversibility to the non-resistant phenotype when the antibiotic is removed from the medium." (ncbi source)
They originally thought antibiotic resistance was evidence for evolution, but actually it is just amplifying genes that are already present. It turns out these epigenetic alterations are inheritable. Because epigenetic changes during the lifetime of an organism are inheritable, this is actually a demonstration of Lamarckism. So at this point, there is more evidence for Lamarckism than evolution. Scientists untainted by bias are realizing this by now, but it will take a while for the average fan boy and sci(fi)blogs to realize it is a broken theory.

Notice it's still called the theory of evolution and not the law of evolution?
That's because it's still theory.
There's no way to recreate results or synthesize such, so they can only theorize about how evolution works.
Even within the same species we have different types of creatures. Look at the k9, they have close to a hundred different types of dog, yet they didn't evolve that way, they were breeding them for that result.
Evolution may be more akin to selective breeding than natural occuring changes. That's what I see anyway.

Natural selection is a primary mechanism of evolution.

Why is it you never post research, only silly dishonest youtube videos?

Why do you always dismiss (or diss) research and peer reviewed publications by pointing out it happens to be discussed and presented in a video that allows pictures of fossils to be shown and the video to even run in the background so one can possibly multitask (especially upon a second or third hearing)? Because the published articles, papers and research discussed and quoted don't fit your marketing narrative?

...'Missing link' in human history confirmed after long debate
I'm not sure this really is THE missing link. I don't see much proof in the PDF, which is linked in the news article linked above. The fossils they have of these skeletons are interesting.

The reconstructed image of Australopithecus sediba is quite attractive
“A. sediba has a strange mix of human and australopithecine qualities. Some say that if the various bones had been found separately, they would have been assumed to belong to different species.”29
This was first noted by Steven Churchill, evolutionary paleoanthropologist at Duke University and co-author of a number of the papers published in Science describing Sediba's remains.
Churchill notes, “If we found [the specimens] as separate parts, we'd probably think they came from different species....”He writes “if” we found them as separate parts. Actually, most of the remains were found as separate parts. Only a few of the bones were found in anatomically credible association. The site consisted of a mixed bone bed of many types of different animals; most of the bones were not found physically connected to one another. Thus it is possible that Sediba is not a legitimate species, but may be a mixture of bones from more than one species, as was the case with Habilis (see chapter 8). As we will show, there are multiple lines of evidence supporting this view.
