The reconstructed pseudo-ancestral Arabidopsis genome, existed prior to the proposed recent polyploidy event, was also utilized in our analysis to further elucidate the evolutionary relationship.
To identify whether the proposed recent transfer is exclusive to the sequenced genomes, we sequenced a region of the transposase gene in different strains of both species and reconstructed their relationships.
Although the concept of cancer stem cells (CSCs, also known as tumor-initiating cells, TICs) has been long proposed, recent advances in the identification of CSCs from several human cancers have provided more convincing evidence for this concept.
The proposed recent origin of macrurus by the recolonization of hainanus onto the mainland would be expected to lead to lower levels of nucleotide diversity in macrurus than in either hainanus or himalayanus.
Let us consider another example, motivated by the proposed recent demographic history of the European human population (Coventry et al. 2010; Nelson et al. 2012; Tennessen et al. 2012; Gazave et al. 2014).
This is unlikely, as recent studies have proposed recent admixture from non-African to African populations (Wang et al. 2013; Wall et al. 2013), and another (Gallego Llorente et al. 2015) has shown that there is European gene flow back into many regions of Africa.
