Shaping the organism: Genetic and environmental influence on development during rapid evolution

Positive selection acts on genetic variation, which in context of the environment an organism develops and functions in, leads to adaptive changes in specific traits

Now moving to the anadromous charr

What is the ancestral state of Craniofacial morphology in Arctic charr?

And how variable are the putative ancestral populations?

#Cilia are essential for early embryonic L-R patterning, but what about later? Tissue/time-specific cilia inhibition in mouse embryos reveals a cell-autonomous role for cilia in #NeuralCrest-mediated #craniofacial & body wall closure defects #PLOSBiology https://plos.io/3NqvcHn

Autonomous and non-cell autonomous role of cilia in structural birth defects in mice

Cilia are essential for establishing early embryonic left-right patterning, but is there a developmental role for cilia following this initial signal? This study uses tissue- and time-specific cilia inhibition in mouse embryos to reveal a cell-autonomous role for cilia in cranial/trunk neural crest-mediated craniofacial and body wall closure defects.

Belcher and colleagues compared the data between two time periods: 2000-2008 and 2009-2017.

The demarcation is significant for marking the beginning of CDC recommendations for regional tracking of #craniofacial defects, as well as when Tennessee banned indoor smoking and the state began collecting data as part of the Pregnancy Risk Assessment Monitoring System...
...Notably, the rate per 10,000 live births dropped from 18.2 between 2000-2008 to 16.9 between 2009-2017.
