homologous structures
What are Homologous Structures?
common anatomical traits between two different species
An organ that is nonfunctional but still on the body
What is the main ingredient needed in Biochemistry?
DNA. Deoxyribonucleic acid.
All species
What party believes more in evolution?
Democrats (67% support the theory while only 43% of Republicans do)
The structure of the human arm's anatomy is closely related to which other species?
Bat's wings
What is the common vestigial organ located in the bottom left corner of the abdomen that was once more useful than the it is today?
The Appendix.
What is one thing that every species' DNA has in common?
The DNA bases. A, T, G, & C.
What is one human structure that dissolves later in fetal development
Tails
Who first came up with the theory of evolution
Charles Darwin
What structure are fish gills much like
Human voice structure
What structure is becoming a vestigial structure
Appendix
What percent of DNA do humans share
99%
What structure do humans, fish, and many other species share during embryo development
Gills
What is the name of the land mass before the contenential drift
Pangea
Why would 2 different species have similar structures
Why is the appendix becoming homologous
Due to diet changes and less need for the breaking down of toxins
What is the importance of shared DNA
The more common DNA there is between species the more closely related they are
What is one reason why embryos seem very similar
Being derived from a common ancestor
What is one opposing view point to evolution
Religion, Big Bang, Etc
how do homologous structure prove the theory of evolution?
Because the structures are in the anatomy of animals but not used it shows that at one point they were needed for something for the animals, but the animals have evolved and the structure is no longer needed or used
How do vestigial organs prove the theory of evolution?
Vestigial organs can show common traits between two or more seemingly unrelated creatures which can show that along the lines they related back to a common ancestor
How does biochemistry prove the theory of evolution?
How does embryological development relate to the theory of evolution?
It shows that in the beginning development of many animals the embryos are very very similar or have structures that will dissolve or become something else that relates to one common ancestor between species.
What species are humans closely related to
Chimps
