If you compare organisms with similar characteristics what indicates recent their common ancestor probably is?
The more similar the two groups are, the most recent the common ancestor probably is.
Similar features in organisms that do not share a recent common ancestor are the result of what?
Similar features in organisms that do not share ancestry means both organisms adapted to their environment. They developed the features to survive.
What do similarities in the DNA of organisms suggest?
That they have a common/similar ancestor. This means that before, possibly these animals came from a similar organism.
Why are a similar number of genes required to make a worm and a human?
Because, in the very distant past, humans and worms had a common ancestor.
The number and location of bones of many fossil vertebrates are similar to those in living vertebrates Most biologists would probably explain this fact on the basis of a the needs of the organisms?
No, b) a common ancestor.
What does the presence of Similar genes in very dissimilar organisms imply?
Common ancestor, or convergent evolution to the same function
If all the genetic information anatomical similarities and fossil record support the same pattern of relationships is the pattern accurate?
Yes. If genetic information is similar, then the organisms had a common ancestor. The more similar the genes, the more recent the ancestor, as in, the more closely related the organisms are. If anatomical patterns are similar to genetic similaritiesm, then chances are the patterns are fairly accurate.
What does the presence of similar DNA sequences in the genes in very dissimilar organisms imply?
It implies that the organism shares a common ancestor.
What does the presence of similar DNA sequence in the genes in very dissimilar organisms imply?
It implies that the organism shares a common ancestor.
What is the signifiance of the similar number and arrangement of bones in a human arm and a bat wing?
It shows that the organisms are somewhat related. It is evidence that they had a common ancestor.
The most recent common ancestor of all land plants was probably similar to modern-day members of which group?
Charophyte.
What is the ancestor of eukaryotes?
Archaebacteria is probably more likely to be the ancestor of eukaryotes because of certain similarities, such as the ribosome of the two groups being much more similar to each other than the ribosomes of bacteria.
