Evolution Life Over Time

Evidence of organisms in the past are based on the following, except:

• Homologous Body Structures

• Similarities in Embryology

• Natural Selection

• Fossil Record

Types of fossils include all of the following, except:

• Cast of an animal track or shell

• Insects/organism trapped in amber

• Decomposed or eaten remains

• Petrification of bone or wood

• Organism frozen in ice

Fossils found in lower layers of rock are said to be older than those found near the surface. Relative dating is based upon

• The Law of Superposition

• The Law of Natural Selection

• Radiometric Dating

• None of the above

Comparison of radioactive and non-radioactive elements in a rock can predict the age of the rock and the fossil in it. This is the premise of

• The Law of Superposition

• The Law of Natural Selection

• Radiometric Dating

• None of the above

A bird wing, bat wing, and dolphin flipper each have about the same number of bones and blood vessels. These are examples of:

• vestigial structures

• embryology

• analogous structures

• homologous structures

An example of a vestigial structure is: *

• the pelvic bone of a whale

• Cat whiskers that help them stay balanced

• a dolphin flipper that propels them swiftly through the water

• Gill slits and tails in human fetuses

A way to see if organisms are related is to study their:

• adaptation

• traits

• variation

• DNA

Rapid evolution by mutation with no middle form found often occurs in bacteria and insect populations. This is known as

• Variable evolution

• Punctuated Equilibrium

• Gradualism

• Mutated embryology

This scientist believed that offspring receive traits that their parents develop their lives and traits that were not used by their parents were lost, and offspring did not inherit them. This theory is known as the Theory of Acquired Characteristics

• Jean Baptiste de Lamarck

• Charles Darwin

• Isaac Newton

• Charles Lamarck

This theory suggests that species with traits best fitted for their natural environment survived and were able to reproduce.

• Theory of Acquired Characteristics

• Theory of Vitalism

• Theory of Natural Selection

• Theory of Spontaneous Generation
