Which organism listed below would have more proteins on common with humans?
Carrot
Bacteria
Chicken
Butterfly
Chicken
Among the organisms listed, the chicken would have more proteins in common with humans. While all organisms, including carrots, bacteria, chicken, and butterflies, share some level of basic proteins, chickens are more closely related to humans in terms of evolutionary ancestry. Therefore, there would be a higher number of common proteins between humans and chickens compared to the other organisms listed.
To determine which organism listed would have more proteins in common with humans, we need to consider the evolutionary relationship between species. Organisms that are more closely related to humans are expected to share more similarities in their protein composition.
Carrots are plants, while bacteria are single-celled organisms. Both of these groups are very distantly related to humans in terms of evolutionary history, so they are unlikely to have many proteins in common with humans.
Chicken and butterflies, on the other hand, are both animals. However, chickens are more closely related to humans than butterflies. Therefore, it is more likely that chicken would have more proteins in common with humans compared to a butterfly.
To further explore this question, scientists use comparative genomics and sequence analysis. They compare the DNA sequences of various species, including humans, chickens, butterflies, and others, to identify similarities and differences in their protein-coding genes. This allows them to determine the extent of protein similarity between different organisms, including humans.
In conclusion, between the four organisms listed, it is more likely that chicken would have more proteins in common with humans compared to a carrot, bacteria, or a butterfly.
