How does the structures of macro-molecules act as an index of relatedness between species?
The structures of macro-molecules, such as DNA and proteins, can be used to infer relatedness between species because they are inherited from common ancestors. By comparing the similarities and differences in the sequences of these molecules among different species, scientists can construct phylogenetic trees that show the evolutionary relationships between them. Closer related species tend to have more similar macro-molecular structures than distantly related species.

What is the significance of genetic relatedness matrix in understanding the evolutionary relationships among different species?
The genetic relatedness matrix helps scientists understand how closely different species are related to each other based on their genetic similarities. By analyzing this matrix, researchers can determine the evolutionary relationships between species and how they have evolved over time.
Do all species require the same macromolecules for their survival and functioning?
No, different species require different macromolecules for their survival and functioning.
What is the study that can provide evidence of evolution?
The study of comparative anatomy and embryology can provide evidence of evolution by showing similarities in structures across different species, suggesting a common ancestry. Fossil records and molecular genetics can also provide evidence by tracing the evolution of species over time and showing genetic relatedness between different organisms.
Why is it useful for scientists to look at embryonic structures when determining evolutionary relationships?
Embryonic structures can provide insights into the shared ancestry of species because they show similarities during development that may not be apparent in adult forms. Comparing embryonic structures across different species can help scientists infer evolutionary relationships and understand how different organisms are related. This can offer valuable information about the evolutionary history and relatedness of species.
Structures as different as human arms bat wings and dolphin flippers contain many of the same bones these bones having developed from the same embryonic tissues How do biologists interpret these?
Biologists interpret these similarities as evidence of a common ancestry. The presence of homologous structures in diverse species suggests that these organisms share a common evolutionary history. The shared embryonic tissues and bone structures provide insights into the relatedness and evolutionary relationships between different species.
How does the structure of macromolecules such as proteins act as an index of relatedness between species?
Organic molecules that just so happen to weigh more than 100,000 daltons, are from that point on then referred to as macromolecules which is related between the species.
What can body structures tell you about how species might be related?
Body structures can indicate shared ancestry among species. Similar anatomical structures suggest a common evolutionary origin, while differences in structures can provide insight into how species have adapted to different environments or ecological niches over time. Comparing body structures helps scientists determine the degree of relatedness between species and understand their evolutionary relationships.
What determines the degree of relatedness between two different species?
The degree of relatedness between two different species can be determined by taxons and a classificaton system. The classification system is used to organize things into different categories based on their evolutionary relationships.

In what two ways G C content data are taxonomically valuable?
It has been observed that there is a correlation between GC content and relatedness between species. This means there is a similarity in GC content in closely relates species. And since taxonomy is involved with classification of organisms, GC contect is an excellent indicator of relatedness. Using this technique, the classification process can be made more precise
Explain why the homologous structures in Part 1 are evidence of evolutionary relationships?
Homologous structures are anatomical similarities in different species that suggest a common evolutionary ancestry. Similar structures in organisms that share a common ancestor are expected to be derived from that common ancestor. By studying these homologous structures, scientists can infer evolutionary relatedness and reconstruct the evolutionary history of species.
How might an understanding of evolution contribute to the development of new drugs?
The relatedness of species allows us to observe different types of organism with the expectation that there'll be homologous structures and behaviour in our own species. That way we can form predictions about behaviour on the level of human genetics, and human cell chemistry.
