Is Domestication Speciation? The Implications of a Messy Domestication Model in the Holocene

DNA Methylation, Speciation and Domestication

More than 150 years after Mendel published his observations on the fundamental laws of inheritance and nearly 65 years after Avery provided unambiguous evidence that the hereditary material is DNA, unraveling the molecular basis underlying phenotypic plasticity and diversity is still a hot topic in genetics. Natural selection counteracts DNA sequence variation, yet losing genetic variation rend...

Early Holocene chicken domestication in northern China.

Chickens represent by far the most important poultry species, yet the number, locations, and timings of their domestication have remained controversial for more than a century. Here we report ancient mitochondrial DNA sequences from the earliest archaeological chicken bones from China, dating back to ∼ 10,000 B.P. The results clearly show that all investigated bones, including the oldest from t...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
