Summary Introduction
Introduction:
There is a variety of organisms present in nature. There is a variety of organisms present in nature. The group of organisms that share certain characteristic features such as ability to interbreed with each other is called species. The process of the formation of a new species from its ancestral species is termed as evolution. It takes millions of years for the evolution of descendants from the primitive organisms.

- Several very distantly related species (e.g., bats, birds, insects) have evolved the capability of flight. The most recent common ancestor of insects and vertebrates likely lived over 500 million years ago and was flightless. This independent evolution of flight in multiple, distantly related taxa is an example of what evolutionary process/pattern? a. Evolutionary reversal b. Convergent evolution c. Speciation d. Synapomorphyarrow_forwardSome embryos share many similarities and are difficult to tell apart, while others are slightly easier. What can you conclude about the similarities and differences between the embryos of different species? Select one: a. The more closely related species show differences from the earlier stages. b.
