This trend involves the need to shift urban facilities to sustainable development, which in turn is linked to the necessity to modernize urban environment in the view of comfort, economy, and ecological compatibility.
The importance of these events is linked to the necessity of organisms to generate novel functions [ 61, 62].
This has been hypothesized for marsupials and monotremes, where the greatly accelerated forelimb development has been linked to the necessity for the embryo to climb to the mother's marsupium to attach to a teat for further development [ 5].
