Stronger genes
More offspring
Better traits
1. What is the definition of species?
trait that helps an organism survive and reproduce
a group of similar organisms that can mate and produce fertile offspring
a well-tested concept that explains a wide range of observations
a group of animals with similar appearance
An adaptation is a trait that helps an organism…
fight better
overproduce
survive and reproduce

They will develop thinner and darker fur
They will lose their ability to swim
They will become herbivores

1.Evolution is...
One animal turning into a completely different animal
Change in one habitat over time
Trait that enhances survival
Gradual change in a species over a long time
The Siberian Tiger kills most of its prey at night. Adaptive characteristics that help it obtain
its food include
Good eyesight, sharp teeth, a powerful jaw, fragile bones, and claws
Good eyesight, muscular legs, a small stomach, sharp teeth
Eyes that see well at night, muscular legs, sharp claws, powerful jaw, and sharp teeth
Eyes that see well at night, muscular legs, sharp teeth and fragile bones.
The main idea of evolution is...
Characteristics of organisms within a population change over time
Only the best organisms survive
Characteristics of organisms can change during their lifetime
Organisms can survive any environment
Modern horsed developed traits thru natural selection. What occurs during the process of natural
selection?
Only the fittest organisms survive and reproduce
Organisms choose mates from other species
Breeders cross organism with desirable traits
Organisms remain exactly the same over many generations
The rapid evolution of a new species can occur by the process of….
Gradualism
punctuated equilibrium
adaptation
survival
What does the fossil record reveal?
Only dinosaurs formed fossils
Species evolve over time
Few organisms are extinct
Mammals have dominated the Earth for most of its history
A new hypoallergenic peanut was developed through artificial selection. Now the only peanuts grown are this new variety. What problem could potentially arise from only having one type of peanut?
No one would be allergic to Reese’s Peanut Butter Cups
With no genetic diversity, the peanuts are more likely to wiped out by disease
There won’t be enough fertile land to grow peanuts
Airlines would serve more peanuts on flights
Which is necessary for speciation to occur?
Adaptation
Mass extinction
Isolation
Acquired traits
