Explore the definition and features of divergent boundaries, as well as examples in this lesson. What is a Divergent Boundary? You've just boiled an egg and are removing the shell. Suddenly; it slips from your hand and hits the floor with a crack. You pick it up to find the whole ...
BoazNegin,GeorgJander, inCurrent Opinion in Plant Biology, 2023 Divergence of specialized metabolites – sometimes is it better to separate Despite numerous examples of convergent evolution in plant metabolism, there are many cases of divergence as well. For instance, nicotine evolved inNicotianaspecies...

Introduction The formation of new species is a fundamental topic in biology. However, many questions regarding the speciation process remain unresolved1,2,3,4, particularly concerning it’s dynamics, i.e., how reproductive isolation changes over time5,6,7. (Here, reproductive isolation, RI hereaf...
(seeMethods). In the second approach, we trained a series of machine learning classifiers to find their own functional category-based definition based on the gene contents from extant Metazoa and Fungi (seeMethods). Then, we scored the ancestral nodes—which were not used to train the ...
In doing so, we rely on a recently published statistic based upon the definition of haplotype allelic classes (HAC). The original measure was modified to be more sensitive to intermediate frequencies in non-model species. A linkage-disequilibrium- based method was also assayed and individual-based...
Therefore, a better understanding of these mechanisms can help move towards a more precise definition of AD across diverse racial, ethnic, and genetic backgrounds. Amyloid-beta1-42 (Aβ42) and Tau, two core cerebrospinal fluid (CSF) protein biomarkers, comprise the major pathologic hallmarks of ...
The Aleutian Trench stretches westward in a giant arc from the southwestern coastline of Alaska. This geological feature is part of the Pacific Ring of Fire, a tectonically active region that encircles the Pacific Ocean. Like most volcanically and seismi
Our PBM studies were limited to the high-confidence hits, and resulted in the definition of binding preferences for 15 proteins (Fig.6A). These exhibited more variation in binding preference than seen within the other TF families. Nevertheless, there was some congruence between the motifs bound ...
