A Baraminological Analysis of Subtribe Flaveriinae (asteraceae: Helenieae) and the Origin of Biological Complexity
نویسندگان
چکیده
WHAT THIS ARTICLE IS ABOUT The subtribe Flaveriinae (Asteraceae: Helenieae) includes a number of plant species sometimes called yellowtops, glowworts, and false broomweed. Different species of this subtribe differ in their chemical pathways involved in photosynthesis. Somes species use a system known as C 3 photosynthesis, some use a system known as C 4 photosynthesis, and others display characteristics intermediate between the two. The authors apply a creationist research method known as baramnology to determine whether the species might have been created separately, or whether they may have descended from a single created ancestral species. They present a large amount of evidence that suggests the entire subtribe belongs to a single lineage which includes additional species not included in the study. The evidence also implies that the originally created ancestor used C 3 photosynthesis, and that the C 4 photosynthesis present in some species emerged since the creation. The characteristics of the intermediate species and the genetics of C 4 species support the hypothesis that latent genetic information may have been present in the ancestor, and activated during post-Flood diversification of the group, possibly through a mechanism called Altruistic Genetic Elements.

Visualizing Baraminic Distances Using Classical Multidimensional Scaling
Baraminology methodology continues to mature, and in this article, the multivariate technique of classical multidimensional scaling is introduced to baraminology. The technique is applied to three datasets previously analyzed in baraminology studies, a Heliantheae/Helenieae (Asteraceae) dataset, a fossil equid dataset, and a grass (Poaceae) dataset. The results indicate that classical multidime...
متن کاملComparative anatomical and morphological investigations of the subtribe Agrimoniinae (Rosaceae) in Iran
The present study was aimed to investigate foliar anatomy and flower, fruit and seed morphology of three subspecies of Agrimonia eupatoria (i.e. A. eupatoria subsp. eupatoria, A. eupatoria subsp. grandis and A. eupatoria subsp. asiatica) and the species of Aremonia agrimonioides, belonging to the subtribe Agrimoniiae (Rosaceae) in Iran. Firstly, plant specimens were collected and then identifie...

متن کاملComprehensive untargeted metabolomics of Lychnnophorinae subtribe (Asteraceae: Vernonieae) in a phylogenetic context
Members of the subtribe Lychnophorinae occur mostly within the Cerrado domain of the Brazilian Central Plateau. The relationships between its 11 genera, as well as between Lychnophorinae and other subtribes belonging to the tribe Vernonieae, have recently been investigated upon a phylogeny based on molecular and morphological data. We report the use of a comprehensive untargeted metabolomics ap...
