One of the key questions in the evolution of the vertebrate lens relates to how these genes could first have come to be expressed at a high level in the tissue that evolved into the lens, such that there could then be selection on their arrangement, abundance, and other properties to enhance their refractive function.
This realization had some impact on phylogenetics, which had historically considered evolution through the lens of systematics rather than ecology.
To strengthen this claim, we now explain in the revised manuscript that: "This realization had some impact on phylogenetics, which had historically considered evolution through the lens of systematics rather than ecology.
The influence that multiple natural and anthropogenic factors, such as land cover, local drainage network, and beach erosion have on the presence, size and evolution of the freshwater lenses in the aquifer is quantified and discussed.
In other words, during mammalian embryogenesis, the development of the lens takes place in parallel with the invagination of the retina to form the eye-cup, whereas we have proposed that during evolution, the formation of a lens did not occur until after formation of the eye-cup.
In his latest project, French artist Maxime Guyon analyses the evolution of photography under the lens of "exaptation", a term originally relating to an evolutionary phenomenon, where one trait of a species shifts toward a new and different function as it evolves further.

Second, we discuss the evolution of those initiatives through the lens of the interaction between social technologies, physical technologies and general institutions.
Citation networks have been widely used to study the evolution of science through the lenses of the underlying patterns of knowledge flows among academic papers, authors, research sub-fields, and scientific journals.
In the evolution of magnetic quadrupole lens technology for nuclear microprobe systems, the pole profile has seen several improvements that have led to increases in the pole tip field for a given lens current.
