What is a homologous structure and what does it show?
== == Homologous provide evidence for evolution because it shows the similarities and how we evolved from the same ancestors
What study can provide evidence of evolution?
Paleontology, genetics, molecular biology, taxonomy, evolutionary development and comparative anatomy, just to name a few.
How does expanding universe provide evidence for big bang theory?
It is not so much that the universe is expanding, but rather the rationalization for its expansion that provides evidence to support the Big Bang Theory. The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that there is an evolutionary expansion of the universe which promotes a finite age for the universe.
How do limestone deposits provide evidence of how plate motions have changed earths surface?
yo but holeLimestone deposits that began as coral reefs provide evidence of how plate motions have changed Earth's surface. These deposits also provide evidence of past environments.
What do magnetic anomalies provide evidence of?
seafloor spreading
The number and structure of what can help to determine evolutionary relationships between species?
The number and structure of chromosomes help determine evolutionary relationships between species. Chromosome comparison helps to provide evidence of the relationships in a species.
What kind of evidence is used by modern taxonomists to classify organisms based on how their relationships changed over time?
Modern taxonomists use molecular evidence, such as DNA sequences, to classify organisms based on how their relationships changed over time. By analyzing similarities and differences in genetic material, taxonomists can determine the evolutionary relationships between different species and create more accurate classifications. This molecular evidence complements traditional morphological and ecological data to provide a more comprehensive understanding of evolutionary relationships among organisms.
How do you know astralopithecus existed?
Astralopithecus is a genus of extinct hominins known from fossil evidence found in Africa. Paleontologists and researchers have discovered various fossils belonging to this genus, which provide physical evidence of their existence and help reconstruct their evolutionary history based on their anatomy and dating methods. The study of these fossils and comparison with other species help scientists understand the evolutionary relationships and existence of Astralopithecus.

What can provide evidence of evolution?
Paleontology, evolutionary biology, molecular cell biology, biochemistry, geology, genetics, biogeography, evolutionary development and so on and so on. The evidence is there in massive amounts. talkorigins.org To start your search. Many links there. NCSE ( National Center For Science Education ) is also a good source.
Who is the parsimony character and secondary character?
In phylogenetics, the parsimony character is the one that requires the fewest evolutionary changes to explain a given set of data. A secondary character is one that is less informative for resolving evolutionary relationships among organisms but can provide additional information when combined with other characters.
What evidence does evolution provide?
The change in allele frequency over time in populations of organisms. An observed and observable fact, especially since gene sequencing has come into it's own. More to the point, evolution provides us with the evidence for evolutionary theory.
What do modern scientists use in classifying organisms that Linnaeus did not use?
Modern scientists use genetic sequencing, molecular studies, and evolutionary relationships to classify organisms, techniques that Linnaeus did not have access to. These methods provide a more accurate and detailed understanding of the relationships between different species.
What is used by modern taxonomists to determine evolutionary or ancestral relationships among taxa?
Modern taxonomists use a combination of molecular data, morphological characteristics, and phylogenetic analyses to determine evolutionary relationships among taxa. Molecular data, such as DNA sequences, provide valuable information on genetic similarities and differences, while morphological characteristics help to identify common ancestry based on physical traits. Phylogenetic analyses, including constructing phylogenetic trees, are used to visualize and interpret these relationships.

What does data from the study of bio geography provide evidence for evolution show?
Data from the study of biogeography provides evidence for evolution by showing patterns of species distribution that can be best explained by common ancestry and adaptation to different environments. It helps in understanding how species have evolved and diversified over time in response to changes in their habitats and geographic isolation. By studying the distribution of species in different regions, scientists can infer evolutionary relationships and historical connections between organisms.
