Similar to the uncinate processes of extant birds, the leverage provided by the sternocostapophyseal projections of pterosaurs likely lowered the work of breathing of the intercostal musculature, and resulted in costal and sternal displacement.
A more recent study of 184 genomes identified 669 orthologous protein families, which cover 561 detailed functional classes that are involved in almost all essential biological processes of extant life, including translation, transcription and its regulation, DNA replication, recombination, and repair, transport and membrane-associated functions, electron transfer, and metabolism [ 10].
Life on Earth, and thus the reproductive and ontogenetic processes of all extant species and their ancestors, evolved under the constant influence of the Earth's 1 g gravitational field.
By addressing the weaknesses of extant process prioritization approaches, the D2P2 accounts for structural and stochastic process dependencies and leverages log data.
And each such reveal is typically only a snapshot of extant processes — i.e. which the whistleblower had access to up to the time the leak was made public.
However, we will develop our proxies through a process of consultation of the extant literature, 53 and ongoing discussion with and feedback from expert clinicians in the fields of pain, cancer and addiction.
To what extent have these evolutionary processes shaped the sRNA content of extant genomes?
Consequently, we unveiled both large-scale evolutionary processes that shape the genomes of extant oomycetes as well as the complex evolution trajectories that lead to highly abundant gene families in this important class of pathogens.
Nee at al. [ 9] first applied the generalized birth-death process [ 29] to molecular phylogenies of extant lineages to extract information on the evolutionary process and proposed a likelihood approach to estimate both speciation and extinction rates (λ and μ, respectively).
"Any object is a possible candidate," they point out, "but because we are engaging in a destructive process, we only take samples from areas of extant damage or loss.
