Adaptive Trait
An adaptation that allows organisms to blend into their environment.
Camoflauge
A theory that explains how organisms change and adapt over time.
Evolution
a group of the same type of organism living in the same area
population
an idea about what might happen that is
based on what you already know
prediction
an event or process that leads to a result or change
cause
An _____________ is changes an organism makes in order to better survive.
Adaptation
Organisms traits change from generation to generation depending on what is needed in the ______________ at the time.
Environment
everything (living and nonliving) that surrounds an organism
environment
a specific characteristic of an individual organism
trait
a result or change that happens because
of an event or process
effect
An adaptation in which an organisms go into a deep sleep during the winter months.
hibernation
What happens to species that do NOT adapt to changes in the environment?
They die out and go extinct
a trait that makes it more likely that an individual will
survive in a specific environment
adaptive trait
a trait that makes it less likely that an individual will
survive in a specific environment
non-adaptive trait
Where do we get genes?
The poison the newts have is a(n) __________________________ against the snakes in the environment.
adaptive trait
How is genetic variation an important part of Natural Selection?
Genetic variation is important because having differences allows some organisms to better adapt and change easier than other organisms.
a group of individuals born and living at about the same time
generation
any difference in traits between individual organisms
variation
a random change to a gene that sometimes
results in a new trait
mutation
What is a a non-adaptive trait
is NO changes an organism makes in order to survive.
A part of Natural Selection in which organisms compete for resources such as food, water, space, mates, and dominance.
Struggle to Survive (competition)
the number of individuals with each trait in a population
distribution
the process by which the distribution of traits in a
population changes over many generations
natural selection
Mutations can benefit organisms because they can
Make an organism more suited to live in its environment
