What is vestigal structure?
Vestigial structures are anatomical structures of organisms in a species which are considered to have lost much or all of their original function through evolution.
What is a vestigal structure?
Vestigial structures are anatomical structures of organisms in a species which are considered to have lost much or all of their original function through evolution.
What kinds of evidence Indicate indicate how closely species are related?
The kinds of evidence that indicates how closely species are related are evidence of DNA and protein structure.
What is a better indicator of the relationship between two organisms structure or function?
Structure is a better indicator of shared ancestry than function. When species share the same structure despite not needing similar structures functionally, it shows that there was almost definitely a common ancestor.
What does descent with modification imply bout the ancestry of different species?
that species today look different from their ancestors
How do you use Common Ancestry in a sentence?
Common ancestry refers to the shared biological heritage between two or more species, indicating that they all descend from a common ancestor. For example, scientists study common ancestry to understand the evolutionary relationships between different species and trace their evolutionary history.
What is notion of homology?
Homology is a concept in biology that refers to similarities between different species due to shared ancestry. In genetics, homology refers to similar DNA sequences found in different species that are inherited from a common ancestor. Homologous structures in anatomy are organs or body parts that have a similar underlying structure but may have different functions in different species.
What is homeobox gene?
A homeobox gene controls the development of a specific structure in an organism. These gene sequences are found in many species (from flies to humans) and can indicate a very distant common ancestor, since one ancient species might have passed on one homebox gene to two separates species.
What is home-box gene?
A homeobox gene controls the development of a specific structure in an organism. These gene sequences are found in many species (from flies to humans) and can indicate a very distant common ancestor, since one ancient species might have passed on one homebox gene to two separates species.
Does homologous mean that structures are similar due to having common ancestry?
homologous structures- same structure/different functions in common ancestors analogous structures-same functions/differnt structures not in common ancestors vestigial-show evolutionary history/structures that arent used anymore (i.e. human appendix/human tailbone)
Plant or animal species that help to indicate environmental change is called?
Indicator Species
How do vestigal organs support evolution?
Shows that over time organs that are not needed or not used that a species can live without begin to appear in offspring. ex) some humans are born without their wisdom teeth
