What is an adaptation?
A change to an organism to adapt to their environment?
100
What 3 traits do all vertebrate embryos have?
Tail, Gills, Eyes
100
What kind of fossils show how an organism changes overtime?
Transitional fossils
100
What is DNA?
DNA is genetic material that acts as an instruction manual from all traits that are passed down from parents.
100
Evolution
Process of a species changing over time to survive
100
What is a cladogram?
A tree or diagram that shows an organisms traits and their relationships.
200
Would sharks losing their tail be a helpful or harmful adaptation?
Harmful
200
What is embryology?
It is the study of embryos (unborn offspring)
200
What kind of structure is wisdom teeth, appendix, and body hair?
Vestigial Structure
200
How do you know two organisms are more closely related based on their DNA?
Their DNA is very similar and have more similars.
200
Embryo
The beginning stages of an organism's development inside a mother or an egg.
200
Based on the Cladogram, what animal is most related to reptiles?
Birds
300
What kind of adaption would a snow rabbit turning from black to white.
Structural Adaptation
300
True or false? Explain.
A seed growing is an example of an embryo that you can study to prove evolution.
False. An embryo grows inside a mother or an egg so a seed is not an embryo.
300
Name the structure
Homologous Structure
300
What animal is most closely related to a rabbit?
Opossum
300
Extinction
When a species is completely or mostly eliminated from the planet.
300
Based on the Cladogram, what animal is least related to primates?
Fish
400
What kinds of adaptations would chameleons changing colors to show off for mates be?
Functional AND Behavioral
400
Base on the embryos, pair the embryos up by most related? (Create 3 groups of 2)
Salamander and fish, Chicken and Turtle, Human and sheep
400
Name the structure
Analogous structure
400
True or false? Explain.
"The less similar two organisms DNA is the more closely related they will be."
False. The DNA will be similar if they are closely related because they inherited the DNA from a common ancestor.
400
Define Variations and give an example.
When a trait in a species can show in different patterns or colors. For example, hair color, eye color
400
Based on the cladogram, what traits do domestic cats and horses have in common?
Backbone, Hair
500
What kinds of adaptations would lizards ability to regrow their limbs be?
A functional and structural adaptation
500
How do embryology provide evidence for evolution?
Embryology provides evidence for evolution because the similarities of the beginning stages show that the organisms all started out as a common ancestor and developed from there.
500
How do anatomical similarities and differences provide evidence of evolution? (2 Ways)
Transitional fossils show how an organism evolved overtime. The similarities in homologous structures indicate a common ancestor.
500
Based on the DNA, which two organisms are least related?
Frog and Opossum
500
Speciation
The development of a brand new species from a
common ancestor.
500
Based on the cladogram, what trait disappeared and came back?
Thin tail
