Larry Daley is a paleontologist found out some Central American Acacia species that have hollow thorns and pores at the bases of their leaves that secrete nectar. He used the species to understand the history and origin of the place. From the given situation, the Central American Acacia species is an example of _____________. *       a. evolution       b. fossil       c. mutation       d. coevolution

10. Many traits seen in organisms are wildly inefficient and prone to malfunction or injury. Why does this finding support the idea of evolution rather than an omnipotent designer? What would we expect for these traits in the intelligent design model? 11. Ants and termites both have highly complex social colonies with queens, workers, and soldiers. Ants evolved from wasps while termites evolved from cockroaches. In this context, are ants vs termites an example of convergent or parallel evolution? How do you know?

I know option "A" is correct, but why isn't option "D" correct?

1.     Is the evolution of more wolf-like traits in the stray dogs of Moscow an example of artificial or natural selection, or perhaps some of both? Why?   1.     Over the past 150 years, some of the stray dogs have developed some unique interactions with humans. What do you predict will happen to the stray dogs and their human “acquaintances” over the next 100 years?
