Sociocultural evolution

Oftentimes, knowledge about the background of authors can lead to a deeper and more thorough understanding of their work. Erin L. McCullough is a Postdoctoral Research Fellow at the Centre for Evolutionary Biology at the University of Western Australia (cite- https://www.researchgate.net/profile/Erin_Mccullough2). She was a PhD student at the University of Montana and has a recently updated blog in which her most recent papers and publications can be found (https://erinlouisamccullough.wordpress…

‘‘I am not apt to follow blindly the lead of other men’’, said Charles Darwin, the man who is considered a revolutionary scientist of the Victorian era. He faced many obstacles regarding his Theory of Evolution which offended the traditional belief of people in the Victorian era because it went against the religious belief that Human were the superior being however his discovery that humans have common ancestors as other animals decoded a new world of science and helped to build our believe in…

Title: HAIR GENETICS A study of DNA sequence variations in melanocortin-1-receptors or MC1R genes found many variants of amino acid found in people who were red-haired but rarely found in the non-red people. Researchers have identified 3 common amino-acid-polymorphisms associated commonly with red haired people viz., R160W, R151C, & D294H. The abbreviated names mean common amino acid types were found in positions 160 151, & 294 in proteins are arginine (R), cysteine (C), arginine & aspartic…

same organism. For example, the structures of the jointed legs in the insects and the birds may have originated with a different purpose given their different skeletal patterns. This assumption led me to believe that their process of convergent evolution occurred somehow later on, not as an original ancestral trait (here a phylogenetic tree would become truly…

I have never been one with strong held believes in the creation of humans or life on earth from god or gods. I lean heavier towards the theory of life evolution. How does what I believe in and what I have read on American Indian beliefs compare to one another. Also how their creations myths and legends compare to my current beliefs and the Christian and other teachings I grow up with. I will be looking at the Apache, Navajo, and Iroquois creation myth and legend stories. One of the first…

(Martin et al., 2016). By using multiple linear regression approach, they have found out that selection reduces diversity at linked neutral sites (Martin et al., 2016). Another study has been conducted to investigate natural selection driving the evolution of reproductive isolation in an Australian wildflower, Senecio lautus. Their results suggested that natural selection can create strong reproductive barriers that differentiate populations with potential to interbreed (Richards et al.,…

Escape and radiate coevolution necessitates the development of a trait or traits in one of the interacting species which provides an extreme advantage over the other and results in its rapid speciation into multiple lineages. The evolution of a particularly effective defense mechanism may render a species effectively immune to predation for a period of time, until a predator species counter-adapts in response, allowing for adaptive radiation unimpeded by predation (Futuyma). Escape…

Results: TAS2R38 Gene he TAS2R38 gene, encodes a protein that allows people to taste the bitter chemical PTC. To begin the experiment, each student tasted two separate pieces of paper to show their individual phenotypes. The first paper was a control, and the second paper was PTC paper. If the individual tasted a bitterness while tasting the PTC paper, they were classified as a taster, and if nothing was tasted they were classified as a non-taster (Leicht 165). Once these expected phenotypes…

Wildlife Conservation Multiple communities, habitats, environments, and ecosystems all coexist with each other to form our planet, Earth. Included in these communities, habitats, environments, and ecosystems are thousands of different species. These species, over centuries, have developed symbiotic relationships with each other as a way of survival. In other words, this “Circle of Life” has been established and for centuries has been effective enough to sustain Earth’s species. However, what…

Introduction It is estimated that there are one trillion species on earth despite all being originated from one common ancestor, LUCA. In this essay the importance and origin of diversity within species and between species is explored using Coleoptera as the taxonomic group. Coleoptera is the most dominant order of insects with 350,000-400,000 species, this is 40% of all insect species (Gillott, 1995) and the largest order in the animal kingdom. The degree of differences between individuals is…
