convergent evolution & homologous structures
convergent evolution & analogous structures
divergent evolution & homologous structures
divergent evolution & analogous structures
What happens in divergent evolution?
Organisms become more similar and yet have homologous structures
Organisms become less similar and yet have homologous structures
Organisms become less similar and yet have analogous structures
Organisms become more similar and yet have analogous structures
According to fossil records, the horses that lived 50 million years ago were much smaller, weaker and slower than modern horses. Which process is most likely responsible for the changes that have led to the increased size, strength, and speed in horses?
evolution by natural selection
migration
inbreeding
commensalism
All dogs have the common ancestor the wolf. This is an example of -
divergent evolution
convergent evolution
Polar bears are believed to have evolved from brown bears. Which explanation best explains why polar bears no longer have brown fur?
Polar bears needed light fur to survive, as a result their fur changed color and they passed the trait on to their offspring
Due to living on snow and ice polar bears' fur changed color and they were able to camouflage themselves and catch more prey
A random mutation caused a change in fur color, this change was advantageous and was passed on to their cubs
Brown furred bears got too hot due to the ice reflecting the sun at a high intensity, and as result the brown bears died out
Which of the following are a line of evidence that supports the theory of evolution? (more than one answer)
Embryology
Fossil record
Comparative anatomy
DNA & biomolecules
Species distribution
