Who was the first person that introduced you to Embryos.
Mrs. Z
A trait that helps organisms survive and reproduce?
Adaptation.
We found the fossils of every species ever?
True/False
False
Types of evidence
Preserved remains of an organism that lived in the past?
Fossils.
What is the goal of Comparative Embryology?
The Goal is to make sense of how embryos develop.
What is the best tool to look at embryos?
A Microscope
Species change gradually over time?
Evolution
Why do offspring inherit adaptations from their parents?
Because they inherit all traits by inheriting the DNA of their parents.
Types of evidence
similar structures that related species have inherited from a common ancestor?
Homologous Structures
What are the traits that all the Animals have in stage 1 of there development?
Gills,Eyes and a Tail.
What is a embryo?
It is a organism in the earliest stage of development.
The process by which individuals that are better adapted to their environment are more likely to survive and reproduce than the other members of there species?
Natural Selection.
Types of evidence
The study of how to compare and contrast Embryos?
Comparative Embryology.
What were the names of 4 out of 8 of the animals that you observed?
Calf,Human,Rabbit,Chick,Pig,Fish,Salamander,
Tortoise.
How many stages are in the development.
3
What is a Embryo?
early pre-birth stage ,baby in the belly, a baby with no features
How would organisms in the area change over time if the color of the area changed?
Any organism that was naturally able to blend in would be more likely to survive, the other organisms would be easier for predators to see.
what % of birth defects have an unknown cause?
at least 50%
Why do the animals Observed look so similar in early stages
the similar animals share some common DNA or common ancestors (Vertebrates)
Why do gills no longer develop in animals other than fish?
Overtime gills were no longer needed in many species because of their environments and they ceased to develop.
What natural event would allow an organism to change color, and eventually the population to change color over time?
Genetic Mutation
Bonus Question
What happens to the tail on the human embryo?
It turns into a tail bone.
