What are spiders relatives?
All spiders are arachnids; they are closely related to scorpions, and distantly related to crabs and ants.
Why are DNA sequences more similar in more closely related organisms?
DNA sequences are more similar in closely related organisms because they share a common ancestor and have undergone fewer genetic changes over time. As organisms diverge and evolve, mutations accumulate in their DNA, leading to differences in their genetic sequences. Therefore, closely related organisms have had less time to accumulate mutations, resulting in more similar DNA sequences.
Which animals are more closely related those in the same order or the same genus?
Animals within the same genus are more distantly related.
True or False If two modern organisms are distantly related in an evolutionary sense then one should expect that they should share fewer homologous structures than two more closely related organisms?
True. The more distantly related two organisms are in evolutionary terms, the fewer homologous structures they are likely to share. Homologous structures are features that have a common evolutionary origin, so closely related organisms are expected to have more similarities in their structures compared to more distantly related organisms.
Is a tiger closely related to the lion?
No, Lions are very distantly related to tigers.
Are mammals related to birds?
Mammals are distantly related to birds. Oddly, if you look at an evolutionary tree, birds are actually more closely related to reptiles than they are to mammals.
How can the relatedness of very dissimilar organisms be determined?
The relatedness of very dissimilar organisms can be determined by comparing their genetic material, such as DNA or RNA sequences. By analyzing these sequences, scientists can identify similarities and differences that can indicate how closely or distantly two organisms are related in terms of evolution. Additionally, studying shared characteristics, such as anatomy or biochemistry, can also provide insights into the relatedness of organisms.
Species that are not closely related and that do not share many anatomical similarities can still be placed together on the same phylogenetic tree by comparing their?
DNA sequences or genetic content. By comparing the genetic material of different species, scientists can determine how closely related they are to each other and their evolutionary history. This allows for the placement of distantly related species on the same phylogenetic tree based on genetic similarities rather than anatomical features.
What are some examples of distantly related keys in music theory?
Some examples of distantly related keys in music theory include C major and G minor, or D major and Bb minor. These keys have different key signatures and are not closely related in terms of their notes and chords.
How are nucleotide sequences used to put organisms in evolutionary order?
When comparing nucleotide sequences in organisms, we find that the organisms that have less differences in their nucleotide sequences are closer related in the evolutionary tree. By this we mean that the common ancestor from which these two organisms evolved is more modern than the ancestor they might share with an organism that shows more difference in the DNA sequencing. Example: the chimps and humans share a common ancestor that is relatively modern because the difference in their nucleotide sequences is just about 1% but the differences between the nucleotide sequence of humans and fish shows lots of differences which shows their common ancestor y much older than the one with chimps.
