Orthologues are genes in different species that evolved from a common ancestral gene through speciation, while paralogues are genes within the same species that evolved from a gene duplication event. Orthologues typically have similar functions due to their shared evolutionary history, while paralogues may have diverged in function over time.

What are the key differences between paralogs and orthologs in terms of their evolutionary relationships and functional roles?

Paralogs are genes within the same species that have evolved from a common ancestor through gene duplication, leading to similar functions but potentially different roles. Orthologs, on the other hand, are genes in different species that have evolved from a common ancestor through speciation, maintaining similar functions and roles.


What is the difference between paralogs and orthologs in terms of their evolutionary relationship and functional similarities?

Paralogs are genes within the same species that have evolved from a common ancestral gene through gene duplication. They may have similar functions but can also have diverged functions due to evolutionary changes. Orthologs, on the other hand, are genes in different species that have evolved from a common ancestral gene through speciation. They are more likely to have similar functions due to their shared evolutionary history.

How does pseudo genes contribute to evolutionary theory?

Pseudogenes are non-functional copies of genes that have accumulated mutations over time. By comparing pseudogenes across different species, scientists can study genetic changes that have occurred during evolution. Pseudogenes provide valuable insights into evolutionary processes and relationships between species.


What are clues that some organism may have a common ancestor?

Similarities in DNA sequences, anatomical structures, or developmental pathways among different organisms are clues that they may have a common ancestor. Additionally, the presence of vestigial structures, which have no current function but are similar to functional structures in related species, can also suggest a shared evolutionary history.

Biologist can compare amino-acid sequence of the same protein from two or more species sequences can be very similar or very different what do the similarities and differences tell us?

Similarities in amino acid sequences tell us the the genes coding for these proteins are similar. Similar genes are due to shared ancestry ie the organisms have evolved from a common ancestor in the past. Differences in amino acid sequence tell us that mutations have occurred in the genes since the organisms separated from the common ancestor. The bigger the differences, the longer the organisms have been separated.


How can we superimpose molecules to analyze their structural similarities?

To analyze the structural similarities of molecules, we can superimpose them by aligning their common features or functional groups. This allows us to compare their shapes and arrangements to identify similarities and differences in their structures.


Is it true that anatomy and physiology are never used to determine evolutionary relationships between phyla?

Anatomy and physiology are used, as they provide insights into the structural and functional adaptations of organisms, which can help determine evolutionary relationships between phyla. These aspects, along with molecular data and other evidence, are important for understanding the evolutionary history of different groups of organisms.


What protist functional group gave rise to terrestrial plants?

Green algae, specifically from the group Charophytes, are believed to be the protist functional group that gave rise to terrestrial plants. They share many structural and biochemical similarities with land plants, leading researchers to hypothesize this evolutionary relationship.


WHAT IS The physiology and functional anatomy of humans and other animals including pathology and comparative studies?

Anatomy is structure, physiology is function. So you would be studying the structure and function of different systems/organs in animals and humans. Pathology is the study and diagnosis of diseases.= =

What do similarities between amino acid sequences indicate?

Similar amino acid sequences can indicate similar protein structure and function. Hydrophobic residues will orient the same way in solution as will polar residues. Charged amino acids are commonly found within or near the active sites enzymes. Similar amino acid sequence can also indicate a similar evolutionary origin known as convergent evolution. This is the same for unique proteins that evolved from a common ancestral protein which is known as divergent evolution.

What does similar mean in science?

In science, "similar" refers to the likeness or resemblance between two or more entities based on shared characteristics, properties, or behaviors. This term can apply to various contexts, such as biological classifications, chemical reactions, or physical properties. Similarity can indicate evolutionary relationships, functional analogies, or patterns observed in data, helping scientists draw conclusions or make predictions. However, it is important to quantify and qualify similarities to ensure accurate comparisons and interpretations.
