Physical characteristics like skeleton and teeth are examples of?
Cladistic analysis
"The examples of cladistic analysis we've discussed so far are based largely on physical characteristics like skeletons and teeth. However, the goal of modern systematics is to understand the evolutionary relationships of all life on Earth, including bacteria, plants, worms, and octopuses. How can we devise hypothesis about the common ancestors of organisms that have no physical similarities?"
However, the goal of modern systematics is to understand the _____________ _________ of all life on Earth, including bacteria, plants, worms, and octopuses.
Because scientist have discovered that a wide range of organisms share genes they can now be used to...
Study genetic diseases, and develop new treatments or technologies
I don't know
study evolutionary relationships
Where do all organisms carry genetic information?
How can you tell if an organism(s) share a recent common ancestor?
The more derived genetic characters they share, the more recent.
Why do genes mutate?
Genes mutate due to social interaction
Genes mutate due to errors in DNA replication, exposure to mutagens, or as part of the natural evolutionary process.
What has helped to make evolutionary trees more accurate?
DNA ANALYSIS
What did molecular analysis show for the bird?
The DNA from American vultures is similar to storks than African vultures
What suggests that american vultures and storks have more recent common ancestors than the american and african vultures do?
DNA evidence
When do scientist often use DNA evidence?
When anatomic traits cannot provide clear answers
Why can anatomical traits be misleading?
What does The Tree of Life illustrate?
It illustrates hypotheses regarding evolutionary relationships
How many domains of life are among the taxa ? (Tree of life)
Tres
One
Four
Three
What is modern evolutionary classification?
Rapidly changing science with a different goal to present all life on a single evolutionary tree.
What are the three domains of the Tree of life?
Bacteria, Archaea, Prokarya
Animalia, Bacteria, Prokarya
Plantae, Animalia, Eukarya
What are the members of the domain "bacteria"?
Unicellular and prokaryote
What do the cell walls contain in bacteria (domain)?
Where do most Archaeas live?
How are bacteria and the archaea domains similar?
What does the domain Eukarya consist of?
The domain Eukarya consist of all organisms that have...
a nucleus
Even though the name of this domain is Unicellular Eukaryotes, people still refer to them as...
Why isn't 'Protist' a good name for this domain; Unicellular Eukaryotes
Many of these organisms are fundamentally different from one another.
The protists are divided into several seperate...
clades
What do those clades include?
Other types of species
Members of the kingdom Fungi are _________ with cell walls containing _______
Hetrotrophs with cell walls containing chitin
Fungi is both...
multicellular and unicellular
What do Autotrophic plants do?
Photosynthesize using chlorophyll
What do the plantae kingdom include?
Land plants
Members of the animal kingdom are...
Multicellular
Multicellular and heterotrophic
What's so incredible about the animal kingdom?
What does the tree of life show?
Clearly illustrates Evolutionary relationships between different species
Is the tree of life accurate?
Not always, it misrepresents a lot of organisms.
What kind of tree would correctly portray the living world?
Cladogram
What is difficult about the cladogram tree?
It would spread out over several pages
