The theory of evolution is the central backbone of biology; therefore, it should be central to biology teaching as well. In the Austrian state curriculum, the topic of evolution is only mentioned twice: first, in grade 7 of the lower secondary school, and second, in grade 12, very close ...
EvoGrader is a free, online, on-demand formative assessment service designed for use in undergraduate biology classrooms. EvoGrader’s web portal is powered by Amazon’s Elastic Cloud and run with LightSIDE Lab’s open-source machine-learning tools. The EvoGrader web portal allows biology instruct...
It is generally supposed that the teleosts represent a higher grade of organization than the ganoids; as a matter of fact, the teleosts, it would seem, have no structural advantage over the cartilaginous fishes in the lesser hardness of the scale and the greater hardness of the skeleton. ...

Although Angiopteris evecta, Equisetum arvense and Psilotum nudum still formed a paraphyletic grade, the relative positions of A. evecta and P. nudum were switched. Placement of A. evecta, E. arvense and P. nudum had high posterior probabilities (1.0 throughout), but bootstrap support for ...
lineages. For both indices, felids, canids and herpestids (mongooses and their kin) cluster around an optimum at the right-hand side of the probability distributions. The first two groups consist of small- to large-sized, long-limbed digitigrade hunters built for strength and speed. In contra...

the research project of van Es and Sherin (2010) is of particular interest. It addresses the influence of teachers’ professional vision on teachers’ thinking and teaching. They analysed the professional vision of seven fourth- and fifth-grade teachers from an urban school, which met once or ...
Fourth, we constructed a phylogenetic tree based on the LACS genes identified in the rhodophyte, glaucophyte, chlorophyte, charophyte, bryophyte, fern, lycophyte, gymnosperm, ANA grade and magnoliales species investigated (Fig. 4D, Supplementary Table S8). The results showed that the clade on ...
