This body of theory looks to the long period of human prehistory to explain contemporary traits that appear evolutionarily non-adaptive, and argues that they initially arose because of the very different lifestyles we enjoyed as hunter-gatherers and horticulturalists.
Although the Mets say that Santana's elbow troubles are normal and did not develop until after he learned he would not pitch in the World Baseball Classic, it is possible that they initially arose because he pushed himself too quickly to be ready for the Classic, even though the Mets did not want him to participate.
Practical challenges that may initially arise could include education and training on sustainable farming techniques, acquisition of tools and materials, and a just system of labour and produce distribution.
Another advantage that can initially arise from relocalization may be to alleviate dosage effects.
Phylogenetic analyses show that the mlrA gene initially arose in α-proteobacteria by vertical evolution, and the two strains from β- and γ-proteobacteria acquired it by horizontal gene transfer.
The team concludes that the cancer mutations initially arose in V. corrugata, but crossed species to Polititapes aureus at some point.
Hierarchical cluster analysis using DNA copy number data confirmed that the paired primary and metastatic samples from the same patients cluster together in all cases suggesting clonality (i.e. that they had initially arisen from a single cell of origin).
The US conflict with the Taliban initially arose due to the Taliban's support and protection of Al Qaeda.
Yet, we cannot ignore the fact that many students in the present study are struggling with the concept that novel traits in organisms initially arise through mutations, and not through some sort of centralized force.
By that they refer to the situation where many students are struggling with the concept that novel traits in organisms initially arise through mutations and not through some sort of a centralized force.
ISX spread around different locations along the fly's X chromosome before these mutations arose; this means that initially none of the 77 insertions carried the two mutations, but now 30% of the 77 elements have the mutations in all flies, and 41% have them in only some flies.
