comparative evolutionary morphologists

Answer 1

those who study the form, function, development, and evolution of anatomical structures

Question 2

evolutionary morphologists rely heavily on

Answer 2

unifying principles such as evolution, developmental trajectories, and the laws of physics

Question 3

function refers to

Answer 3

what systems do and how they perform certain tasks

Question 4

biological role is

Answer 4

how a function is used in nature

Question 5

evolution is

Answer 5

changes in the genetic makeup of populations over time

Question 6

phenotype

Answer 6

an organism’s appearance

Question 7

homology

Answer 7

similarity in organs from different organisms as a result of inheritance from a common ancestor

Question 8

ontogeny recapitulates phylogeny

Answer 8

developmental stages reveal earlier stages from one’s ancestry

Question 9

metameric or serial homology

Answer 9

successively repeated features in the same individual

Question 10

Answer 10

parts of the body can change independently of others
