How can the process of evolution by natural selection be modelled?
Explain why natural selection is important for evolution.
organisms with the best characteristics for their environment will survive.
organisms with less favorable traits in their environment will die and not reproduce.
heritable traits that are helpful help organisms survive and reproduce.
giraffes
camouflage
stick insects
camouflage
peppered moths
camouflage
grasshopper
long necks
finches
beak shape.
What are the key features of evolution by natural selection?
coloration
eyes
hair
skin
camouflageable
fight diseases
size
What is evolution by natural selection?
share a common ancestor
each species has its own unique set of heritable traits.
organisms evolve to be better suited to its environment.
Process when organisms adapt and change.
evolution occurs when helpful traits get passed to offspring.
natural selection leads to speciation
speciation is where a species gives rise to a new and distinctly different species
many traits are heritable
mutations occur from an error while copying DNA
mutations can be harmful, neutral, or helpful.
mutations are an important source of genetic variation.
a scientific theory
individuals can only adapt not evolve
overtime the entire species evolved leaving the old species extinct
similarities of embryos is an example of evolution
theory of evolution is seen as the main theme that ties majority topics of biology together.
genetics
population biology
anatomy and physiology
embryology
evolution is a change in genetic traits over generations.
