Fossil Record
The fossils over time trapped in rock layers over the last 600 million years.
fossil record
The boat that Darwin traveled on for 5 years.
Beagle
a physical feature that an organism has that helps it survive- like green scales to blend in with leaves.
adaptation
a leftover body part that has no current function in a modern animal- like a leg bone in a whale that only swims and doesn't walk.
vestigial organ
the genetic information stored in the nucleus of cells
DNA
fossils on the bottom layer are older, ones on the top are more recent
relative dating
This scientist specialized in collecting butterflies for a living.
Wallace
when many species adapt and change in a new location from an original species
adaptive radiation
body parts that look different but come from same ancestral part- seal flipper bone and human arm bone
homologous structures
the genetic makeup of a species changes over time
genetic drift
When an organism develops alongside another organism, like an orchid and an orchid moth that pollinates it.
coevolution
This scientist published the book "On the Origin of Species" in 1859.
Charles Darwin
being able to live until adulthood and reproducing gives an organism this
fitness
body parts that look similar but do not come from same ancestor- example: wings of insects and wings of birds
analogous structures
Adenine, thymine, guanine, cytosine are the four _______ in DNA.
nitrogenous bases
The death of an entire species
extinction
This scientist published a book on evolution called Darwinism.
Wallace
the location that animals are found on the globe
biogeography
Body parts that match their surroundings- like a black moth on a dark tree
camouflage
A change in DNA that results in a change in the look of an organism- like a three eyed cat.
mutation
a group of the same organism that can successfully breed to make fertile offspring
species
The idea that organisms are selected for in nature to survive if they are well suited for their environment
natural selection
change in species over geologic time
evolution
Name three body parts that are likely to be preserved as fossils.
teeth, bones, skull, shells, etc.
traits that are passed on from parent to child are called this
heritable traits
