Answer:
Comparative anatomy.
Explanation:
Comparative anatomy is a branch of science in which we study about similarities and differences present in different organisms. This type of study is very important for the classification of living organisms. Comparative anatomy tells us about the evolution of an organism. Scientists study DNA, embronic structure and the internal structure of species to see the evolution of different organisms.
Explanation: Survivorship curves fit three types. A Type I curve shows a low death rate in early and middle life but the death rate increases steeply in old age. A Type II curve shows a death rate is more constant throughout the lifetime of the species.
