Oops, a [Teoria da] Evolução se esqueceu dos eucariotos
Mas ainda assim um fato...
Em seus momentos de honestidade os evolucionistas dizem todo o tipo de coisas interessantes. Que tal este artigo de 1998 onde os evolucionistas admitem que “One of the most important omissions in recent evolutionary theory concerns how eukaryotes could emerge and evolve.” [Uma das mais importantes omissões na recente teoria evolucionária diz respeito como os eucariotos poderiam surgir e evoluir]. A [teoria da] evolução omitiu como os eucariotos podiam surgir e evoluir? Isso seria igual a Física omitindo a gravidade, a política omitindo as eleições ou o baseball omitindo os homeruns [O maior ponto neste jogo – destaque deste blogger]. Mesmo assim, este artigo veio um século depois de os evolucionistas começarem a insistir que está além de toda dúvida razoável que as espécies, e isso seria que todas as espécies, surgiram espontaneamente.
Como poderia a origem espontânea de todas as espécies ser além de toda a dúvida razoável se a teoria tinha omitido os eucariotos que, como você aprendeu na aula de biologia, são as células mais complicadas com um núcleo e que constituem, hummm, as plantas e os animais?
Nós não sabemos como as plantas e os animais evoluíram, mas nós sabemos que eles evoluíram?
Bem, sim. Quanto à origem dos eucariotos, e tudo mais por esta razão, é meramente um problema de pesquisa, que não deve ser confundido com o fato da evolução. Você sabe, há o fato da evolução e a teoria da evolução. O fato da evolução nos garante que as espécies surgiram espontaneamente, mas não nos diz como surgiram. Isso é para a teoria da evolução destrinchar.
Tudo isso faz sentido para os evolucionistas porque o fato da evolução não vem da ciência.

Abstract
One of the most important omissions in recent evolutionary theory concerns how eukaryotes could emerge and evolve. According to the currently accepted views, the first eukaryotic cell possessed a nucleus, an endomembrane system, and a cytoskeleton but had an inefficient prokaryotic-like metabolism. In contrast, one of the most ancient eukaryotes, the metamonada Giardia lamblia, was found to have formerly possessed mitochondria. In sharp contrast with the traditional views, this paper suggests, based on the energetic aspect of genome organization, that the emergence of eukaryotes was promoted by the establishment of an efficient energy-converting organelle, such as the mitochondrion. Mitochondria were acquired by the endosymbiosis of ancient alpha-purple photosynthetic Gram-negative eubacteria that reorganized the prokaryotic metabolism of the archaebacterial-like ancestral host cells. The presence of an ATP pool in the cytoplasm provided by this cell organelle allowed a major increase in genome size. This evolutionary change, the remarkable increase both in genome size and complexity, explains the origin of the eukaryotic cell itself. The loss of cell wall and the appearance of multicellularity can also be explained by the acquisition of mitochondria. All bacteria use chemiosmotic mechanisms to harness energy; therefore the periplasm bounded by the cell wall is an essential part of prokaryotic cells. Following the establishment of mitochondria, the original plasma membrane-bound metabolism of prokaryotes, as well as the funcion of the periplasm providing a compartment for the formation of different ion gradients, has been transferred into the inner mitochondrial membrane and intermembrane space. After the loss of the essential function of periplasm, the bacterial cell wall could also be lost, which enabled the naked cells to establish direct connections among themselves. The relatively late emergence of mitochondria may be the reason why multicellularity evolved so slowly.
