Eliminating correlations from evolutionary ecology

terrarium eco system

De novo creation of olfactory receptor genes clearly links food odors via amino acid substitutions to cell type differentiation in mosquitoes, and in nematodes, flies, honeybees, etc. It would be surprising if cause and effect did not extend to vertebrates…

The wrong picture of our evolution

translocated chromosome

“We have built a picture of our evolution based on the morphology of fossils and it was wrong.” I’ve repeatedly cited the latest literature, especially in the context of Skull 5. The article linked below is another clear representation of…

The smell of cancer

What Does Cancer Smell Like? By VERONIQUE GREENWOOD Published: November 19, 2013 Excerpt:  Diseases can subtly alter people’s fragrance. In the normal course of metabolism, thousands of waste products are swept out in our breath, blood and urine, or simply…

Transcription Factor-MicroRNA-Target Gene Networks Associated with Ovarian Cancer Survival and Recurrence Excerpt: “MicroRNAs (miRNAs) are small, non-coding RNA molecules that bind to complementary sequences on target mRNA transcripts, and thus, regulate gene expression at the post-transcription stage. Transcription factors (TFs)…
