Evidence for Evolution
Petrified wood is an example of what kind of evidence for evolution?
Fossil
Water and minerals replace biological molecules in a dead organism.
Fossilization
These marine animals are closely related to hippos.
whales
Organisms are born or hatch with characteristics that are different.
Variation
Breeds of the American Kennel Club are produced this way.
Selective breeding or Artificial Selection
Base sequences that code for a protein can be this kind of evidence for evolution.
DNA
Dr. Castori's favorite fossil.
Whale vertebrate
What is the name of the trait that was selected for in African Elephants?
Tusklessness.
Dogs are born with traits based on genes from their mother and father.
Inheritance
Similarity in body parts between different species is called this.
Homologous
Embryology or comparative anatomy
The name for the ancient continent that broke apart and created the continents of today.
Pangea
These organisms evolved during the Industrial Revolution.
Peppered Moths
As a population changes it does so because of selective pressure.
Adaptation
This famous scientist studied finches in the 1800s.
Charles Darwin
The small hind-leg-like structures found in whale skeletons are an example of this.
Vestigeal structures
This structure is found in embryos of humans, fish, turtles, and chickens.
(Pharyngeal) Gill Slits
These animals evolved different color fur because of a cooled lava flows in a desert.
Rock pocket mice.
The environmental conditions determine traits that allow certain organisms to survive and reproduce.
Selective Pressure
Based on DNA comparisons, which of the following animals is most closely related to whales? Dogs, Hippos, Giraffes, Cows
Hippos
Comparisons of embryos of different animals is this kind of evidence.
Embryology or Comparative Anatomy
This happens randomly and may produce a favorable trait for an organism.
Genetic mutation
Where is the oldest rock layer in the Grand Canyon
At the bottom of the canyon.
Some organisms are better fit for the environment, survive longer and reproduce more.
Differential survival or natural selection
The name for scientists who study fossils.
Paleontologist
