Testing a Strong Prediction of Universal Common Ancestry

Testing a Strong Prediction of Universal Common Ancestry

In 2013, a paper was published by researchers from New Zealand in the journal PLOS ONE  entitled "Beyond Reasonable Doubt: Evolution from DNA Sequences". After reading it recently, I was surprised to find that it seems to have flown under the radar in popular science circles. I couldn't find any references to the article in … Continue reading Testing a Strong Prediction of Universal Common Ancestry

Alcohol Tolerance in Fruit Flies: A Classic Case of Molecular Adaptation Refuted

Alcohol Tolerance in Fruit Flies: A Classic Case of Molecular Adaptation Refuted

Two weeks ago, an article was published online in the inaugural issue of the new journal Nature Ecology & Evolution entitled "Experimental test and refutation of a classic case of molecular adaptation in Drosophila melanogaster". As the title suggests, the article soundly refutes a classic example of molecular adaption that was first established in a seminal paper by McDonald and … Continue reading Alcohol Tolerance in Fruit Flies: A Classic Case of Molecular Adaptation Refuted

Chromosome 2 Fusion and Bayes Theorem: Support for Common Ancestry After All

By now I would hope everyone is familiar with the fusion resulting in human chromosome number 2, but for those who aren't, or would like a quick refresher, here is a short video of Dr Ken Miller explaining it: Note that that the fusion was a strong prediction of the theory of common descent, in other … Continue reading Chromosome 2 Fusion and Bayes Theorem: Support for Common Ancestry After All

Dating Processed Pseudogenes

Dating Processed Pseudogenes

I'm sure most of you are already pretty familiar with pseudogenes - they can be considered "vestigial" genes because they've lost their original protein-coding function, and are often totally non-functional. Processed pseudogenes are a specific kind of pseudogene that has been produced through the action of reverse transcriptase. A functional protein-coding gene is transcribed into … Continue reading Dating Processed Pseudogenes
