Fitness and selection
Being able to survive and reproduce
What is fitness?
Morphology and this can be used to create a cladogram.
What is DNA, Amino Acid or Protein Sequences?
This is required for speciation to occur.
What is reproductive isolation?
The one bone, two bones, many bones and digits pattern seen in the arm of a human, flipper of a whale, and the wing of a bird.
What are homologous structures?
A change over time.
What is evolution?
An environmental pressure that impacts whether an organism can survive and reproduce.
What is a selective pressure?
This animal is most closely related to humans.
What are chimpanzees?
A male zebra and a female donkey producing a zonkey or zeedonk is an example of this.
What is reduced hybrid fertility?
Wisdom teeth and appendix in a human.
What are vestigial structures?
Analogous structures arise due to this.
What is convergent evolution?
The type of selection that occurs when the extremes of a trait are both equally selected for.
What is disruptive selection?
This lineage is the least closely related member of the clade
What is the outgroup?
A pine tree's pollen cannot come in contact with the pine cone is an example of this type of reproductive isolation.
What is mechanical isolation?
What are analogous structures?
Evolution occurs because of this.
What are genetic mutations?
The average birth weight of 7 pounds for human babies is an example of this type of selection
What is stabilizing selection?
This group of organisms are most closely related to the T.Rex.
What are birds?
Eastern spotted skunks mating in late winter, while western spotted skunks mating in the fall is an example of this type of reproductive isolation.
What is temporal isolation?
When a species diversifies rapidly into many other new species due to a change in the environment.
What is adaptive radiation?
The process by which organisms that are better adapted to survive and reproduce in a given environment live.
What is Natural Selection?
The increase of dark Rock Pocket mice on a lava field is an example of this type of selection.
What is directional selection?
The point at which a new branch on a phylogenetic tree arises shows this.
What is a common ancestor?
Spineless stickleback fish live in a freshwater lake, while spiny stickleback live in the ocean. This type of speciation caused the evolution of stickleback fish.
What is allopatric speciation?
A morphological or genetic characteristic shared between species due to a common ancestor.
What is homology?
An example of this is the Goldendoodle.
What is artificial selection/selective breeding?
