Question 10
We explored the process and pace of evolution by natural selection in sexual animals like us. We discovered several important things about this process. Which of the following is the most accurate and complete description of several of those insights?
New mutations occur all the time but natural selection must wait for these to arise one-by-one for evolution of anatomy and behavior to occur, making the process slow.
New mutations occur all them time and sexual reproduction reassorts them, limiting the rate of evolution of anatomy and behavior and making the process slow.
Large amounts of cryptic and overt variation exist in animal populations and are continuously re-assorted by sexual reproduction potentially making evolution very fast.
New mutations are made by the organism very abundantly any time it finds itself confronted by a new adaptive challenge, making evolution very fast.
a.New mutations occur all the time but natural selection must wait for these to arise one-by-one for evolution of anatomy and behavior to occur, making the process slow.
b.New mutations occur all them time and sexual reproduction reassorts them, limiting the rate of evolution of anatomy and behavior and making the process slow.
c.Large amounts of cryptic and overt variation exist in animal populations and are continuously re-assorted by sexual reproduction potentially making evolution very fast.
d.New mutations are made by the organism very abundantly any time it finds itself confronted by a new adaptive challenge, making evolution very fast.
Explanation / Answer
New mutations occur all the time but natural selection must wait for these to arise one-by-one for evolution of anatomy and behavior to occur, making the process slow.
Mutations arise and natural selection causes harmful ones to be deleted and beneficial ones to amplify. The process of evolution is very slow.
