Amino Acid Sequencing
This type of sequencing compares proteins between organisms to see how similar they are.
Amino acid sequencing
Wings of insects and birds are considered this type of structure because they serve similar functions but have different origins.
Analogous structure
The study of the shape and structure of body parts is called this.
Anatomy
DNA, RNA, and protein comparisons are all examples of this type of evidence for evolution.
Biochemical evidence
This field studies where species live and why they live there.
Biogeography
Amino acid sequencing helps scientists study this process, which explains how species change over time.
Evolution
Analogous structures are a result of this type of evolution, where unrelated species develop similar traits.
Convergent evolution
Comparative anatomy can show evolutionary relationships by studying these similarities in body structures.
Homologous structures
Similarities in biochemical sequences suggest that organisms share this.
Common ancestry
Islands often have unique species because of this type of geographic influence.
Isolation
When comparing two species, a higher number of matching amino acids usually means this about their relationship.
They are more closely related
The fins of a shark and the flippers of a dolphin look similar but evolved separately. They are an example of this.
Analogous structure
The study of internal organs, bones, and muscles is a branch of this field.
Anatomy
Scientists often compare this molecule to determine how closely species are related.
DNA
Patterns of species distribution over time can provide evidence for this scientific theory.
Evolution
Scientists often use this technique to identify mutations in amino acid chains.
Protein analysis or amino acid sequencing
Unlike homologous structures, analogous structures do not suggest this about the species.
Common ancestry
Studying anatomy across species can provide evidence for this principle, first described by Darwin.
Descent with modification
This type of biochemical analysis can reveal how proteins have changed over time across species.
Amino acid sequencing
The study of fossils in different regions contributes to this branch of biogeography.
Historical biogeography
This term describes the specific order of amino acids in a protein that determines its structure and function.
Primary structure
The wings of a bat and the wings of a butterfly are analogous, showing that similar environmental pressures can lead to this phenomenon.
Functional similarity or adaptation
This type of anatomy focuses on microscopic structures, like cells and tissues.
Microscopic anatomy (or histology)
Biochemical evidence can sometimes contradict this type of evidence based on physical traits alone.
Morphological or anatomical evidence
Similar species found on continents that were once connected by this ancient landmass provide strong evidence for evolution.
