The most recent phylogenetic data suggests that bacteria and archaea may be more closely related than archaea and eukarya true or false?
TRUE
What is difference between Linnaeus classification and phylogenetic classification?
Linnaeus classification is based on physical and observable characteristics of organisms, categorizing them into hierarchical groups like kingdoms and species. Phylogenetic classification, on the other hand, is based on evolutionary relationships and genetic similarities among organisms, organizing them into groups that reflect their evolutionary history. Phylogenetic classification provides a more accurate depiction of the evolutionary relatedness between different species compared to Linnaeus classification.
Which theory states that the more recent species are change descendants of earlier species?
mostly eveloution
What is phylogenetic relatedness?
Recency of common ancestry. Species A is more closely related to species B than to species C if (and only if) the last common ancestor of A and B lived more recently than the last common ancestor of A and C. The concept can be applied not just to species but also to organism, populations, or genes.
What kingdom is placed at the bottom of the phylogenic tree?
The kingdom placed at the bottom of the phylogenetic tree is typically the most ancient or primitive kingdom, which is Monera (bacteria). This placement reflects the evolutionary history and divergence of life on Earth, with more complex organisms branching off from simpler ones.
Can phylogenetic trees ever change?
Yes, they change as we learn more about the organism.
Two species are classified in the same genus. How does this classification reflect the evolutionary relationship between the two species?
it means the species shared a common ancestor in the recent past
Were species with shared ancestors classified more closely?
Yes, species with shared ancestors are classified more closely together in taxonomic classifications. The more recent the shared ancestor, the more closely related the species are considered to be. This is consistent with the principles of evolutionary relationships in biology.
What theory states that the more recent species are changed descendants or earlier species?
The so called "theory" of evolution, though it has essentially been proven to be a fact.
What is the comparative and superlative of recent?
The comparative of "recent" is "more recent," and the superlative is "most recent."
Why are more recently deposited rock layers more likely to contain fossils resemble existing species than older rock layers?
The more recent rock layers will contain fossils that are more similar to current species because of evolution. The older the fossils, the more evolutionary changes will exist between them and current species which accounts for the greater differences.
Determine genetic difference between two organisms on a phylogenetic tree?
Please be more precise about which is the other organism you are referring to.
