Answer:
Aspects of evolution are constantly being challenged and explored in light of new evidence
Explanation:
The whole idea of evolution has to do with the fact that organisms developed into their present form from simpler life forms. According to Oxford dictionary, evolution is; ''the process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.''
Evolution depends on evidence from fossil records. Evidences that support the theory of evolution continue to be amassed as science advances. Hence, aspects of evolution are constantly being challenged and explored in light of new evidence.
For this reason, the evolutionary history and development of whales is being hotly debated and there has recently been a major shift in our understanding of the processes used to detail whale evolution.

Answer:
Fertilised ovum from sheep + cell in sheep's mammary gland isolation
Diploid one cell isolated + nucleus from ovum
Nucleus inserted into empty ovum
Ovum implanted in uterus of unrelated sheep
Ovum develops into foetus
Explanation:
In this process a nucleus from a fertilised ovum was removed and replaced with a diploid nucleus of a cell from the mammary glands of another sheep. The ovum was implanted into the sheep's uterus. The resulting foetus "Dolly" born similar to donor sheep.
