Numerous environmental changes made by humans have led to the extinction of hundreds of vertebrate species. The loss of Phylogenetic Diversity (PD), the extinction of essential species for ecosystem function, and the decoupling of species interactions are well-known effects of these impacts. The disruption of biological patterns is a less well-known effect of extinctions caused by humans. Such modifications may hinder our ability to identify underlying natural laws, leading to skewed assessments of how evolution functions.
Anthropogenic biases may develop from the selection influence of humans, with some features making species more susceptible to extinctions brought on by humans. For instance, it is well known that larger mammals have a higher risk of going extinct than smaller mammals. Numerous biological trends relating to body size are weakened by this anthropogenic effect, including Bergmann's rule, which states that animals grow larger at higher latitudes. Examples of how people can influence observed natural events are mostly limited to biogeographic patterns of mega faunal extinction, while extinctions can conceal significant evolutionary shifts [1].
Birds are a great group to study in terms of how significant evolutionary changes might be masked by extinctions brought on by humans. Despite being the most well-known major clade in terms of phylogeny, geographic distribution, and species features, there have been numerous extinctions that may be attributed to humans. Even while anthropogenically extinct species make only a small amount of the current biodiversity, they can display different features from live counterparts, which would alter the depiction of evolution in the extant avifauna. Flightlessness is one characteristic where this distortion may be particularly pronounced since it makes species more susceptible to human hunting and predation by non-native species that humans have introduced such rats and cats [2].
Multiple bird clades have independently experienced secondary flightlessness, or the loss of flight, which is typically accompanied by a variety of morphological, physiological, ecological, and genetic alterations. Our ability to research the true evolutionary structure and geographic spread of this phenomenon is, however, constrained since extinctions caused by humans have significantly decreased the diversity of flightless species. These studies may be underestimating the bias and, consequently, the impact of extinctions on our inference of evolutionary transitions because human influence on biodiversity is pervasive throughout the world and may be traced back thousands of years [3].
In spite of the fact that 95 percent of bird species are currently living, there are still significant biases due to the imbalance in trait distributions between living and extinct species. These findings underscore the need for improved interdisciplinary collaboration between paleontological, ecological, and evolutionary studies and provide new insight into the broader issue of sample biases in comparative phylogenetic analyses. If the omitted species constitute a non-random sample of the total, macro evolutionary study of species with genetic information may result in a higher bias. Evolutionary research concentrating on such features may reflect anthropogenic impacts rather than basic biological principles, as human-related extinctions have been proven to be extremely selective in regard to species traits. Here, we show that the developmental way from the sky to the ground in birds was not close to as uncommon as it shows up from concentrating on the surviving avian phylogeny. Environmentally and phylogenetically assorted flightless birds involved the greater part of the world's archipelagos when people showed up, filling the specialty of missing well evolved creature species. Albeit other flightless species likewise existed and went terminated in pre human times anthropogenic annihilations are supposed to be exceptionally particular as for flightlessness. Since flightless species frequently developed in light of the shortfall of vertebrates, they were especially powerless against human appearance and the related presentation of non-local warm blooded creatures [4].
The effects of these misfortunes are probably going to be undervalued, considering that numerous species will have become terminated without leaving a fossil record a significant number of which are reasonable likewise to have been flightless. The excess flightless bird species currently address a minuscule part of a once bigger gathering with huge environmental significance for key biological system capabilities including seed dispersal, fertilization, and herbivory. Flightless birds feature equal changes including a set-up of conduct, morphological, and natural changes that have become generally deleted by human driven eradications [5].
