Question

Which statements are correct concerning the evolution model:

• incorporates higher order life forms which parallel each other

• only a few simple life forms give rise to new kinds of life which will increase in complexity

• all life on earth developed from nonliving matter of natural unknown processes

• each lower life form can be traced back only to the life form corresponding to a basic kind

Answer 1

The correct answer will be option-only a few simple life forms give rise to new kinds of life which will increase in complexity.

Step-by-step explanation:

The evolution is a branch of study which deals with the study of the history of life on earth based on the evidence.

The evolutionary model suggests how life existed and the way life flourished on earth in the past. The conclusions were made on the basis of fossils that life evolved from simple organisms and moved towards complexity. The simple organisms like prokaryotes evolved to form complex eukaryotes which formed the complex organism.

Since, evolution explains about how life diversified on earth and not about the origin of life therefore, the selected option is the correct answer.

Answer 2

The evolutionary theory of the life suggests the complex organism were derived from the simpler ones. Initially, the life started from single celled organism.

The heterotrophic anaerobes are thought to be the first living cells evolved on earth. Later, these bacteria differentiated, and lead to the formation of other multi-cellular organisms.

Hence, the correct answer is option only a few simple life forms give rise to new kinds of life which will increase in complexity .
