Comparative Anatomy
Name the 3 main types of comparative anatomy.
Homologous structures, analogous structures, and vestigial structures
Which is the genus and which is the species:
Panthera leo
Genus = Panthera
Species = leo
What is the strongest form of evidence for evolution?
DNA / DNA Sequencing
Give an example of artificial seleciton
Dog breeds, vegetables, fruits, farm animals, domesticated animals, horses, etc.
What is the most-ordered item at McDonald’s?
French Fries.
What is an analogous structure?
Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related but in which the bones are used for different functions.
What acronym do we use to remember:
D-K-P-C-O-F-G-S
Did King Philip come over for good soup?
What type of evidence changed scientific understanding of animals being related? For example, the elephant shrew.
DNA
Give an example of natural selection.
Moth wing colors, pocket mice colors, green caterpillars on green leaves, polar bears living near snow, any animals blending in to their environment.
What word was named the 2024 Oxford Word of the Year, most often used by Gen Z and Gen Alpha?
Brain rot
What is a homologous structures
Homologous Structures are organs or bones in different species that have similarities in structure, but have different functions. Show evidence of common ancestry.
What does D-K-P-C-O-F-G-S stand for in species classification?
Domain, Kingdon, Phyllum, Class, Order, Family, Genus, Species
Name the 4 main types of evidence of evolution.
Fossils, embryology, comparative anatomy, and DNA
What is artificial selection
Type of breeding where the human makes decisions about who will mate or what genes will have the opportunity to be passed on.
Which sport uses a pommel horse?
Gymnastics
Name 3 examples of vestigial structures
Hip bones in whales and boa constrictors, skinks legs, human tailbone, wisdom teeth, muscles for moving ears, body hair, and appendix
If 2 organisms are in the same Order, are they also in the same Phyllum? Explain
Yes, because taxonomy becomes more specific and order is more specific than phyllum.
According to these 3 images, who can we tell have common ancestors?
Fish, salamander, tortoise, chickens, and rabbits
Define fitness
Ability of an organism to survive and reproduce in its environment.
What is the most popular game-day dip across the U.S.?
Buffalo chicken dip
What is a vestigial structure?
Structures that have no apparent function and appear to be residual parts from a past ancestor.
The taxonomic names are listed below for 3 organisms. Which two organisms are most closely related?
Canidae: Canis latrans
Canidae: Canis lupus
Canidae: Vulpes vulpes
Bonus! What is the common name for all 3 orgainisms?
Canis latrans and Canis lupus
Why is DNA the strongest form of evidence for evolution?
Because it is specific, exact, and all organisms have it, so scientists can track patterns between all organisms.
Define natural selection.
Organisms with traits that make them better suited to their environment survive and reproduce more successfully than others, passing on those advantageous traits to their offspring
What is the most-watched YouTube video of all time?
