Question
1. Explain how natural selection may lead to evolution using a specific example not already describe in the text book or lecture. Identify the selection pressure and the adaptive trait in your example.
2. Why is taxonomy important and useful? Include a brief description of the three Cs.
3. Define carrying capacity and briefly discuss the factors that affect the earth’s carrying capacity for the human population. Do you believe we will reach earth’s carrying capacity for the human population (soon)?
Explanation / Answer
1. Natural selection may lead to evolution theis can be exemplified by Charles Darwin's statement of "Descent with modifications" which means passing the traits of parents to the offspring. On this very concept Charles Darwin based his theory of evolution. By using this statement of descent with modification he want to say that with each passing generations only the traits which are useful for the coming generations will be passed upon and this is how evolution takes place. An example of this can be regional differences in functional responses of egg production rate which reflect genetic differences between western and eastern populations of Calanus finmarchicus in Atlantic Ocean.
2. Taxonomy is important and useful as it helps us in locating, describing, and naming taxa, particularly species. This branch of science involves grouping and thus naming various organisms on the basis of their shared characteristics.The three Cs stands for the different scientists classification that is Chatton1925(2 empires), Copeland1938(4 kingdoms) and Cavalier-Smith 1998(6 kingdoms).
3. The carring capacity is the maximum number of organisms that our earth can carry or in different words the amount of resources which are adequate for the number of people is known as carring capacity. Yes, the way we are increasing our consumptions of resources, it seems like we'll hit the carring capacity soon in the near future.
