Evidence For Evolution Flashcards
What are the four evidences
Comparative genomics, comparative studies of proteins, fossil records, comparative anatomy and embryology
What is/are vestigial structures
-Greatly reduced structures that no longer serve a purpose
-similar features show relatedness and possible common ancestors
What is/are pentadactyl structures
Is a 5 digit limb (found in most vertebrates)
What is embryology
-The study of specie’s embryos and the comparison between them
-similar features show similarity and possible relatedness
What are retroviruses
-A virus with an envelope which changes DNA sequence
-if two species have that DNA sequence it shows they both come from a common ancestor
mtDNA info
-Mitochondria DNA only passes on through females (mom-son/daughter)
-can compare organisms mtDNA and show relatedness
What is comparative genomics
-The comparison of DNA sequences between species
-similar DNA sequence shows relatedness
Hybrid DNA
Seperate strands on DNA from two species/organisms are put together, then it goes through denaturing through temp. The higher temp required shows that the seperate strands are more related
