Species and Evoltion
This is a group of similar organisms that can mate with each other and produce fertile offspring
What is a species ?
This term is the process by which individuals that are better adapted to their environment are more likely to survive and reproduce.
What is Natural Selection?
This is a trait that increases an organism’s ability to survive and reproduce.
What is an Adaptation?
Comparing body structures between different species, similar structures inherited from a common ancestor are called this.
What is Homologous Structures?
This is where Darwin studied the animals.
What is the Galapagos Islands ?
This term is when an organism produces more offspring than can possibly survive.
What is Overproduction?
This is one of the main ways a new species can form. (HINT: Kaibab and Albert's squirrels)
What is a group of individuals becomes isolated?
_____________________ is when the species evolves slowly, but surely
Gradualism
The process of gradual change over time is called this.
What is Evolution?
This what the differences between individuals within a species is called.
What is variation ?
Changes in the genetic structure of these cells do not affect the future development of any offspring.
What are body cells?
This theory is when a species evolves rapidly.
What is Punctuated Equilibrium?
Similarities in the early development of chickens and opossums suggests that these species share a common this.
What is Ancestor?
In the process of natural selection, the organisms that are best suited to their environment are most likely to survive and do this.
What is reproduce?
If a species becomes isolated, variations that are this will allow a new species to form.
What is different?
The more closely two species are related, theoretically, the more similar their this is.
What is DNA?
A horse and a donkey have a baby, but the offspring is infertile because the horse and donkey belong to this.
What are different species?
This explanation helps us to understand how natural selection leads to evolution.
What is helpful adaptations accumulate among surviving members of a species?
Natural selection can only act on those traits that are controlled by these.
What are Genes?
Scientists combine evidence from fossils, body structures, DNA, and more to determine this among species.
What is Evolutionary Relationships?
