Which of the following would you expect to have the most similar DNA sequences?
Which pair of species would you expect to have the most similar DNA sequences? Jackals and wolves are both in the genus Canis, so they should have very similar DNA sequences.
Which of the following aquatic organisms might display limbs during embryonic development?
Dolphin embryos show early development of hind limb buds. Match each of the six types of evolutionary evidence outlined in the book to the specific examples of evidence for the evolutionary relationships among aquatic mammals.
Which of the following is an example of macroevolution?
An example of macroevolution is the evolution of a new species. One mechanism that drives evolution is natural selection, which is a process that increases the frequency of advantageous alleles in a population. Natural selection results in organisms that are more likely to survive and reproduce.
Which is an example of macroevolution quizlet?
Which of the following is an example of macroevolution? A tadpole changes form into a frog. A population of fish slowly changes tail shape. A dinosaur species evolves over time into a bird species.
Which organism would be expected to have the most similar DNA sequences compared to humans?
WASHINGTON, Wed., Aug. 31, 2005 — The first comprehensive comparison of the genetic blueprints of humans and chimpanzees shows our closest living relatives share perfect identity with 96 percent of our DNA sequence, an international research consortium reported today.
Which species is most closely related to Bos taurus?
Bison and cattle (Bos taurus) are closely related, and bison are sometimes classified as Bos bison (Boyd et al.
Did dolphins evolve from dogs?
Well the simple answer to your question is that dolphins did not evolve from dogs. ... The dolphins belong to the cetacea (a phylogenic classification) and dogs belong to the carnivora. Both of these have evolved from a group called the mesonychidae.
Were dolphins land animals?
Fossil remains show dolphins and whales were four-footed land animals about 50 million years ago and share the same common ancestor as hippos and deer. Scientists believe they later transitioned to an aquatic lifestyle and their hind limbs disappeared.
What land animal did dolphins evolve from?
The evolution of dolphins, or Delphinus, is believed to have started with the Pakiectus, a four legged, land walking mammal. The Pakiectus dates back to approximately 50 million years ago. Throughout the centuries, these animals have gone through drastic changes to become the modern day dolphin.
What's an example of convergent evolution?
Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated. ... Another lineage stayed put in the ocean, undergoing tweaks to become the modern shark.
What is macroevolution in zoology?
Macroevolution refers (most of the time, in practice) to evolutionary patterns and processes above the species level. It is usually contrasted with microevolution, or evolutionary change within populations.
What is genetic drift example?
Example of genetic drift: a population of rabbits with alleles B and b, both alleles are present in equal frequencies p = 0.5 and q = 0.5 if 10 parents reproduce the probability of having an offspring with alleles B or b is 0.5; however, by chance, a slight difference in the offspring allele frequency might occur due ...
What Makes 2 organisms the same or different species?
Most evolutionary biologists distinguish one species from another based on reproductivity: members of different species either won't or can't mate with one another, or, if they do, the resulting offspring are often sterile, unviable, or suffer some other sort of reduced fitness.
Which grouping includes all of the protists?
The emerging classification scheme groups the entire domain Eukaryota into six “supergroups” that contain all of the protists as well as animals, plants, and fungi that evolved from a common ancestor (Figure 1).
