History of Life Quiz
On a phylogenetic tree, the longer the branch, the longer the length of time that occurred before the next split in groups.
False
Scientists create clades by using:
homologous traits
Which is true about unrooted taxonomic trees?
They show a relationship between species
Which phylogenetic models incorporates the possibilities of horizontal gene transfer?
A branch with more than two lineages is called a
polytomy
Eukaryotic cells may have evolved in all the following ways except:
Mitochondria and Nucleus-first hypothesis
Maximum parsimony is used to
determine most likely phylogenies
Transposons are most closed associated with
jumping genes
Phylogenetic relationships do not show how organisms are similar or different, but do provide information on shared ancestry.
True
Some species are more "evolved" than other species since they have longer evolutionary histories than others.
False
transduction
Dichotomous keys are typically used when classifying organisms using:
phylogenetics
WRONG?
Classifying organisms into a system with increasingly inclusive groups is called
taxonomy
Horizonal or lateral gene transfer only occurs in prokaryotic organisms.
False
Convergent evolution is associated with homologous characteristics.
False
Which of the following is the most inclusive grouping?
phylum
WRONG?
A shared derived character describes a characteristic on a phylogenetic tree that all organisms on the tree share
False
WRONG?
One of numbers 11-17 are wrong but I don't know which one. The submitted quiz would not tell me.
