Aye-Aye Has Its So-Ugly-It’s-Cute Genome Sequenced

Aye-aye has its genome sequenced by science

The rare aye-aye from Madagascar, once nominated by The Inquisitr as the second ugliest animal on earth, has had its genome sequenced so that its DNA won’t be lost. Oh, the humanity. The team included researchers from Penn State along with Edward Louis, Director of the Madagascar Biodiversity Partnership, and the new genetic information was published today in the Proceedings of the National Academy of Sciences.

Among other things, the researchers produced a complete genome sequencing of three separate populations of the aye-aye, including a northern group that they described as “genetically distinct, with strong differentiation from other aye-ayes.” Aha. Is that a hint? Will the species eventually be split to form two different species?

Can there be two second-ugliest animals in the world?

If the aye-aye is new to you, that’s probably because it’s only found on the island of Madagascar — and, even there, it’s a rarely seen nocturnal species. Yet, like humans, it’s a primate. As a member of the lemur family, it’s considerably more primitive than the other primate that recently got its genome sequenced, our very near relative, the Neanderthal.

The Neanderthal, of course, is completely extinct, and its genome had to be recovered from fossil bones. The aye-aye appeared to be well on its way to extinction for awhile, and the International Union for the Conservation of Nature (IUCN) had it red-listed as an endangered species between 1986 and 2000.

More recent sightings have shown that the aye-aye has a larger population than we previously realized, but it’s still considered “near-threatened,” and it’s a good idea to monitor how it’s doing.

If you want to get to know the aye-aye better without traveling all the way to Madagascar, a large island offshore Africa, then I suggest you visit the Penn State site where Louis has published an engaging photo gallery of some of the aye-ayes he encountered along the way.

Do you think it’s really the runner-up in the world’s ugliest contest? If you ask me, the aye-aye is actually kinda cute.

    The recent news is that scientists have discovered some snippets of DNA from an ancient fish that can cause mice to grow limbs. This is wrongly being hailed as evidence that fish had developed legs. Isn't it interesting that the fish they got the DNA from didn't have legs!

    These snippets of DNA from the fish seem to be "triggering" mechanisms. They can only trigger ("turn on") genes, such as genes for formation of limbs, but, if the genes for limbs first exist, and since genes for limbs exist in mice then these triggering mechanisms, even if from a fish, will work. None of this means fish evolved legs.

    Imagine an evolving fish having part fins and part feet, with the fins evolving into feet. Where’s the survival advantage? It can't use either fins or feet efficiently. These fish exist only on automobile bumper stickers!

    Genetic and biological similarities between species are no proof of common ancestry. Such similarities are better and more logically explained due to a common Genetic Engineer or Designer (yes, God) who designed similar functions for similar purposes in various species. Genetic information, like other forms of information, cannot arise by chance, so it's more rational to believe that DNA or genetic similarities between species are due to intelligent design.

    The genes already exist for micro-evolution (variations within a biological kind such as varieties of dogs, cats, horses, cows, etc.), but not for macro-evolution (variations across biological kinds such as from sea sponge to human).
