With which animal(s) do we share a very fundamental architecture of the brain? What are at least three animal structures that would be analogous to bacterial flagella? Explain the three common features of reptiles, birds and mammals. Physical features that are similar in organisms which are not...
Sex chromosomes in plants and animals and mating type loci in fungi share strikingly similar genomic features and evolutionary processes, and this convergent evolution across kingdoms reflects similar selection forces that drive their formation (Fraser et al. 2004). Sex chromosomes at advanced stages ar...
Bats act as a natural reservoir for many viruses, including coronaviruses, and have played a crucial epidemiological role in the emergence of many viral di
which were cloned using similar tools. The first publication documenting organism cloning described nuclear transfer of a blastula cell into an enucleated frog oocyte[1]. It would take more than 60 years until Dr Keith Campbell and Sir Ian Wilmut created the world's first mammalian clone from a...
We question the idea that SSB necessarily presents an evolutionary conundrum, and suggest that the literature includes unchecked assumptions regarding the costs, benefits and origins of SSB. Instead, we offer an alternative null hypothesis for the evolutionary origin of SSB that, through a subtle ...
that resemble humans36,37,38,39,40. Companion animals also share very similar environments (e.g., shared sleeping quarters, diets, experiences, toxins, stressors) with their owners. The close relationship of companion animals to humans combined with their relatively shortened life makes them well...
[3]. During these decades of debate, a recurrent premise has been that non-human animals (hereafter “animals”) experience the events in their life in a similar way to humans, and therefore people should treat animals with care and have respect for their welfare [1]. Along with the ...
Examination of genes associated with multicellularity in animals showed that the new filastereans contain a cell-adhesion gene repertoire similar to those of other species in this group. Syssomonas multiformis possessed a smaller complement overall but does encode genes absent from the earlier-...
We hold, therefore, that the correct ethical principle to apply when the interests of animals and humans are salient is the principle of “equal consideration of similar interests.” We regard it as wrong to give less consideration to the interests of an animal than we give to similar human ...
Similar comparisons can be made with improving weaning weights in meat-type breeds like the Texel sheep and Boer goat. This application of transgenic technology could lead to improved growth and survival of offspring. Protein Expressed Species Where Expressed Promoter Reference Lysozyme goat Bovine α...
