Next fossil, Tiktaalik roseae, has been one of the last important
discoveries in paleontology.
By: Obsidian Soul
1. Why is this fossil important?
Because it explains the transition between aquatic animals
(fish) and terrestrial animals with four limbs.
2. It is considered a transitional fossil. What does it mean?
It connects two different group of organisms, in this case fish
with four limbs terrestrial organisms.
3. About the two groups it relates, which characteristics did
Tiktaalik have of each one?
It had scales like fish, but it had ribs and lungs, flat head, it
could move the neck, and inside its fins it had the basic
structure of bones found in terrestrial animal limbs (one
bone-two bones-little bones-digits).

1. What do they represent?
They represent fossils, remains of organisms from other
eras.
2. Explain how they can be formed. After they die, they
decompose, remaining their hard parts: shells, bones,
exoskeletons. They can be under layers of rocks, inside
amber, or sometimes we just find their prints in rocks.
3. What kind of information can they provide us? They give us
information about organisms that lived in the past, some of
them extinct, others are the ancestors from today’s
organisms and help us explain their evolution.

1. What is a vestigial structure?
A structure in a species with no function, remain of a past
function in the organism.
2. What kind of information a vestigial structure gives us?
About past structures in the species that had specific
functions, and the lost them.
3. Give more examples of vestigial structures.
The coccyx in humans (remnant of tail), as well as the plica
semilunaris inside of the eye (remnant of the nictitating
membrane), or hind legs in a whale.

EVIDENCES
Complete each definition with the right evidence:
1. ____________: Study of remains of organisms from
other eras.
2. ____________: Study of similarities between DNA,
amino acid sequences and other molecules in organisms.
3. ____________: Study of the distribution of organisms on
Earth and the possibility of their connections.
4. ____________: Primitive organs with no longer
functions, they talk about the past.
5. ____________: Study of homologies and analogies in
organisms.
6. ____________: Comparing embryos in development to
discover similarities.

1. Which two organisms do you think are more closely related?
Why?
The human and the chimpanzee, because their sequences
are more similar, with less differences.
2. What kind of evidence of evolution is this?
This is the molecular or biochemical evidence.
3. What structures can be studied in this field of investigation
to find the relationships between organisms?
They can compare sequences of DNA, proteins, sequences of
amino acids and other molecules.
