"Cladistics", or is it the bagel?

What is phylogenetic constraint?
Phylogenetic Constraint is like a basic body plan. It can be modified (what evolution does) but it can't be fully changed. Vestigial features (things like the human appendix which is a remnant of our ancestors, but is no longer used) provide evidence of common ancestry and phylogenetic constraint. :)
What is phylogenetic line?
An ancestor-descendent line; the sequence of ancestral taxa leading from some point in the ancestry through time to a specific taxon. For example, our complete phylogenetic line would include all taxa that are in the ancestry of both apes and humans as well as all taxa ancestral to modern humans from the time the human line split from the ape line.
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 percentage of African-Americans have European ancestry?
60% of African Americans have some European Ancestry, while 75% have European or Native American ancestry. That leaves 40% with no European Ancestry, 85% with no Native American ancestry and 25% with only African ancestry.
Why do scientist use classification in solving problem in life science?
Classification helps organize species into more easily recognizable patterns, and these patterns illustrate the evolutionary history of each species. The classification pattern pretty clearly reveals a nested hierarchy of forms, into which even fossil specimens can be placed. A nested hierarchy is what we would expect if most or all species shared common ancestry or, in other words, had undergone evolution.
What is the phylogenetic system of classification?
The phylogenetic system of classification organizes organisms based on their evolutionary relationships. It groups species together based on their shared ancestry and common descent, reflecting the evolutionary history of life on Earth. This system aims to show how different organisms are related to each other through a branching tree-like structure known as a phylogenetic tree.

Phylogeny refers to what aspect of individuals?
Evolutionary relationships
What are the differences between the morphological species concept biological species concept and phylogenetic species concept?
The morphological species concept differentiates species by their physical traits, basically. The biological species concept defines a species as generally organisms that breed with others of the same species; rather a genetic isolation concept. The phylogenetic concept is based on evolutionary relationships and is the concept used by cladists.

What data is used in systematics that stresses both common ancestry and the amount of change observed among groups?
The data that is used in systematics that stresses both the common ancestry and the amount of change that is observed among groups is cladistic. Cladistic is the classification in which items are grouped together.
What do genus have to do with evolution?
Nothing much. A genus is simply a label we attach to a particular group of species sharing a common ancestry. It's more to do with classification than with understanding evolution.
How do evolutionists try to use the classification system to reinforce their worldview?
Evolutionists use the classification system to show the hierarchical relationships between organisms, highlighting the shared ancestry and evolutionary history among different species. By showcasing how organisms are grouped based on their shared characteristics, evolutionists argue that this classification system provides evidence for common descent and the process of evolution.
What is high yella?
High yellow is a term used to define a black person who has a high proportion of white ancestry. Those who are considered high yellow are of the African descent, but do not have the darker complexion.
What is the ancestry of Jared Leto?
He has Cajun ancestry
What happened in our recent ancestry that did NOT happen in the chimps recent ancestry?
An event that happened in our recent ancestry that did not happen in the recent ancestry of chimps was the Industrial Revolution.
