Mechanisms and Patterns of Evolution

The process in which a single species or a small group of species evolves into diverse forms that live in different ways is called

• coevolution

• macroevolution

• adaptive radiation

• convergent evolution

The process by which unrelated organisms come to resemble one another because they live in similar environments is

• coevolution

• macroevolution

• adaptive radiation

• convergent evolution

What contributed to the adaptive radiation of mammals?

• the evolution of plants

• the mass extinction of most dinosaurs

• coevolution with insects

• continental drift

Which of the following is an example of convergent evolution?

• bird’s wing and fish’s fin

• human’s arm and bird’s wing

• shark’s fin and dolphin’s limb

• human’s leg and dolphin’s limb

Large-scale evolutionary changes that usually take place over long periods of time are referred to as speciation

• true

• false, it is called macroevolution

• false, it is called microevolution

Evolution that happens between species as a response to changes in each other is called

• punctuated equilibrium

• adaptive radiation

• coevolution

• extinction

• convergent evolution

Long periods of species stability that is interrupted by periods of rapid change is what type of evolution?

• adaptive radiation

• punctuated equilibrium

• coevolution

• convergent evolution

• extinction

What was the selection pressure that caused adaptive radiation in the Galapagos finches?

• Type of evolution acting on the finches.

• Type of food available

• Type of mates available

• Type of material available for building nests

One example of coevolution is that between

• birds and bees

• flowering plants and insects.

• dinosaurs and mammals

• humans and other primates.

• worms and fishes.

(REVIEW, UGHHHHH) The idea that attributes acquired by an individual during its lifetime (for example, increased or decreased muscular strength due to more or less physical work) were passed on to the offspring is known as _________ and is attributed to _________.

• adaptation, Wallace.

• natural selection, Darwin

• inheritance of acquired characteristics, Lamarck.

• genetics, Mendel.

• none of the above is correct.
