Biogeography is the study of the distribution of species in different regions through the history of life on Earth. The map belo

w shows the approximate arrangement of five continents in Earth's past. The distributions of several ancient species, based on fossil evidence, are also shown.
On which modern-day continents would you be most likely to find organisms that share Cynognathus as a common ancestor?

1Points

A
Africa and South America only

B
Africa, Antarctica, and South America only

C
Africa, Antarctica, India, and South America only

D
Africa, Antarctica, Australia, India, and South America

<u>Answer</u>: A) Africa and South America only

As shown in the map, the fossil evidence suggests that Cynognathus lived on the modern day continents of South America and Africa. Thus, from this distribution and the fragmentation of the ancient landmass into today's continents, result in the distribution of Cynognathus offspring species also only within the continents of Africa and South America.

If there is dissolved carbon dioxide in the water, are underwater plants able to perform photosynthesis? Explain why or why not.
Alenkasestr [34]

Answer:

Plants undergo photosynthesis, which is the process where carbon dioxide, water, and sunlight are transformed into sugar and oxygen. Even though they look different than terrestrial (land) plants, aquatic plants, or plants that live on the water's surface or submerged underwater, also undergo photosynthesis.

Match the type of of evidence for evolution with the correct example. analogous structures vestigial structures homologous struc
gogolik [260]

• Homologous structures: Both Ostriches have wings similar in form to those of their ancestors, but that do not allow the birds to fly.

Homologous structures are those that have structural similarities but are different in function. For example, if we look at the anatomical structure of a bird’s wing, it is very similar in structure with a human arm. However, over the course of time they have evolved to perform different functions.

• Vestigial structures: The inner ear bones of mammals have evolved from bones that form the jaws of reptiles.  

Vestigiality refers to the process in which some structure lose their function over the course of evolution in some specie but they are functionally normal in other species.  Such a structure is the inner ear bones of mammals which donot perform an important function in mammals but do perform in reptiles.

• DNA sequence data: Both Genes involved in RNA replication are conserved among bacteria and animals, suggesting a common evolutionary origin.

The sequencing of genetic data is an excellent method of finding the evolutionary histories and relatedness of different organisms. This field of sciences is called phylogenetics and the mentioned example is the result of phylogenetics.

• Analogous structures: The jointed legs of insects and vertebrates arose independently, indicating a different evolutionary origin.  

Analogous structures are those that have similar function but they look very different in structure or anatomy. This is because they have been evolved from different ancestors and perform different functions. One example of these structures is mentioned, The jointed legs of insects and vertebrates that look different bur perform same function.
