Your friend finds an organism that is multicellular. Which single question about it, if answered yes, would indicate its kingdom?

F
Evolutionary trees, such as the one below, are finished products and are not subject to revision. Is this statement true or false, and why?
False, because future discoveries may revise these relationships.
Match each event with its major evolutionary significance.
Land plants and vertebrates diversify-Continents separate from Pangaea. Eukaryotes evolve-Oxygen levels increase in the atmosphere. Vertebrates colonize land-Plants cover Earth's land.
This chapter details the work of Xu Xing, a paleontologist who specializes in the evolutionary relationships of feathered dinosaurs. Order the following events chronologically to describe how paleontologists like Xu Xing gather evidence and explain the possible relationships among feathered fossils.
New feathered fossils are discovered. Shared derived traits of new fossils are compared to existing fossils. New evolutionary tree is drawn to hypothesize relationships. New evolutionary tree is published. Alternate evolutionary trees are proposed that alter the published hypothesis.
Place the evolutionary events in the order they occurred, from earliest to latest in history.
Pants colonize land vertebrates colonize land Reptiles dominate land mammals dominate land
In the transition to life on land, organisms had to handle many of the functions basic to life very differently in the new environment than in water. Match each basic life function with the adaptation organisms developed.
Some organisms developed limbs instead of fins-movement Plants developed pollen and seeds.-reproduction Plants developed rigid cell walls.-support
According to the evolutionary tree below, species G shares a common ancestor with species B.
T
Humans evolved during the age of the mammals.
T
Species that are very closely related should possess a high number of shared derived traits.
T
According to the evolutionary tree below, which event happened first in evolutionary history?
The A-B clade diverged from the C-D-E-F clade.
You find an organism that is multicellular, moves around, and eats other organisms. What organism is it most likely to be?
an animal
According to this figure, what is true of the relationship between modern birds and Archaeopteryx?
archaeopteryx and birds share a common ancestor.
Wolves, dogs, and coyotes are all canines and belong to the same genus. To which of the following genera do they likely belong?
canis
What is the lowest (most specific) level of the Linnaean hierarchy that these two mammals (human and domestic dog) share?

Diversity of plant and animal species usually -during mass extinctions and -in between mass extinctions.

Extinction of dominant groups of organisms often leads to what outcome?
dominance of a new group of organisms
According to the evolutionary tree below, which pair of species is/was the most closely related?
e and f
Place the events that occur during a mass extinction in order, from earliest to latest.
environment changes dramatically many group of species go extinct new groups of species take over the available resources
In the Cretaceous extinction event, 40% of all plant and animal species are believed to have gone extinct.
f
Prokaryotic organisms likely evolved from eukaryotic organisms.
f
The location of Archaeopteryx within an evolutionary tree of dinosaurs and birds is fixed and cannot change.
f
There is a debate among many biologists as to whether the many species we see today are the products of evolution from a common ancestor.
f
According to the Linnaean hierarchy, which level of classification would be less inclusive than class but more inclusive than genus?

Xu Xing studies feathered dinosaurs and the origins of bird flight. He has discovered more than 60 species of dinosaurs. If you discovered a fossil that looked like a dinosaur but had feathers, which of the following would most likely be true?
its ancestor was a theropod.
Match each of these human taxonomic groups to their correct level of classification.

An evolutionary tree is a diagram that indicates evolutionary relationships among organisms. Each branch is referred to as a -, which connects to other branches at places called -, which represent -between the organisms on the branches. When two organisms possess a high number of shared derived traits, it is evidence that these two are -related.
