"In cell biology, a mitochondrion (plural mitochondria) is a membrane-enclosed organelle that is found in most eukaryotic cells."
"Endosymbiotic theory suggests that eukaryotic cells first appeared when a prokaryotic cell (a bacterium) was absorbed into another cell without being digested. These two cells are thought to have then entered into a symbiotic relationship forming the first organelle. This organelle would eventually become today's mitochondrion, and the genome of that first absorbed bacterium would have given rise to today's mitochondrial DNA as evolution progressed."
"In the cells of current organisms, the vast majority of the proteins present in the mitochondria (numbering approximately 1500 different types in mammals) are coded for by nuclear DNA, but the genes for some of them, if not most, are thought to have originally been of bacterial origin, having since been transferred to the eukaryotic nucleus during evolution."
"Currently, human mtDNA is present at 100-10,000 separate copies per cell, with each circular molecule consisting of 16,569 base pairs with 37 genes, 13 proteins (polypeptides), 22 transfer RNA (tRNAs) and two ribosomal RNAs (rRNAs)." (All quotes from Wiki)
So the very convincing 'endosymbiotic theory' implies that the vast majority of the mitochondrial genes migrated from the mitochondria to the cell nuclei. This is easily understandable within panpsychism, because genes can be animated by psychons (e.g. during recombination the gene psychons are obviously active). Therefore genes can behave in a way similar to animals. If gene psychons feel confortable in company of other genes, it becomes understandable that a mitochondrial gene, after having accidently left a mitochondrion and entered a cell nucleus, gets integrated in the nuclear DNA. This fact may still be explainable in a superficial way within reductionist materialism.
But what about the proteins being coded by these genes? How could they find back to their workplaces in a mitochondrion? These proteins even have to pass both the outer and the inner membrane of the mitochondrion before reaching their destinations. And it doesn't help if from time to time some mitochondrial proteins accidentally reach their working places, as it was the case for the gene, having accidentally migrated from mitochondrial DNA to nuclear DNA. A substantial part of the proteins must be able to find their now far-away working places, otherwise there are not enough proteins working in the mitochondrion.
So we must ask: How probable is it that hundreds of mitochondrial genes received during or after their transfer into the nucleus by random mutations (blind chance) exactly such specific sequences which direct their corresponding enzymes back to the mitochondria?
BTW, how could such genetic information, telling the proteins to enter a mitochondrion look like? Consistent logical reasoning is enough to conclude that such an information cannot exist in form of DNA. So the information must come from elsewhere.

One of the simplest refutations of neo-Darwinism:
The upright gait was only one of many traits which had to evolve in us after our separation from chimps. For that to happen, the structures of bones, of muscules and of tendons had to gradually change. Let us ignore that in fact the bone structure (involved in the upright-gait evolution) alone consists of several bones with each several traits.
So let us make the completely unrealistic simplification that one 'progressive' single-step mutation in the genetic factor of each (i.e. bone, muscle and tendon) structure is enough to entail a relevant increase in fitness.
Let us further assume that the probability of such progressive mutations in newborns is each as high as 10^-5. So we conclude that among 10^15 newborns (i.e. a billion newborns of a million generations), only one indivudual will carry all three necessary mutations.
Because a change in only one or two of the three involved structures cannot lead to a relevant increase in fitness (rather the contrary), it becomes obvious that the upright gait cannot have evolved in a neo-Darwinian way.
