Charles Darwin
who was Charles darwin
English naturalist and biologist.
natural selection
organisms better adapted to their environment are more likely to survive and reproduce. It's an evolutionary process.
variation
Organisms within a population possess natural, heritable differences in their physical and genetic traits
WHy is reproduction important?
Allows the organism to pass on traits to their offspring.
Why do animals with helpful traits live longer?
They are better suited to their enviorment
what book did Darwin publish
On The origin of species.
mimicry
copying behaviors of another organism to represent that organism.
inheritance
hey can be passed down from parent to offspring. Over time, these advantageous genes become more prevalent in the population
How do organisms with favorable traits affect future generations?
more likely to survive and reproduce.
WHy does thicker fur help animals depending on the weather?
It keeps them warm during the winter.
what was the name of Darwin's ship
HMS Beagle
camoflouge
to hide and disguse yourself to blend in and hide yourself from predators.
selection
individuals with traits best suited to their habitat are more likely to survive and successfully reproduce
What role does genetic variation play in reproduction?
Genetic variation creates differences with offspring.
HoW do adaptations help organisms survive in their environment.?
to protect species from predators and the environment/ weather.
which islands helped Darwin develop his ideas about natural selection.
The galpagos islands
population
total number of inhabitants in a geological area.
time
Evolution takes generations. Given sufficient time and reproduction
Why do some organisms produce many offspring while others produce only a few?
Some produce many because many may not survive, while others invest more care in fewer offspring.
examples of physical and behavioral adaptations in animals/ species?
camoflauge thick fur and claws help them.
what observations helped darwin form his theory.
His global observations that he took during his voyage helped explain natural selection.
adaptation
organism charging to better suit the enviorment
ex. peppered moths.
adaptation
As the environment exerts pressure on a species, the traits that aid in survival and reproduction are selected for
How can reproduction lead to evolution over time?
Over tons of generations successful traits are passed down more often
Why might an adaptation that helps one species survive not help another species?
Different species live in different environments and have different needs.
