Q

what are the three rules for how a species gets its binomial name

  3. designate a holotype specimen

Q

what is an example of sexual dimorphism in modern animals

17
Q

A

variation between young and adult individuals of the SAME species

18
Q

_____ is the normal variation that exists among individuals of a species

A

individual variation

19
Q

what is an example of individual variation

A

eye color and hair color in humans

20
Q

plastic deformation (change in bone) can result in ….

A

taphonomic variation

21
Q

_______ define a species as a group of organisms that can successfully interbreed

a) biological species concept
b) morphological species concept

A

a

22
Q

which species concept can be applied to modern animals and plants

A

biological species concept

23
Q

true or false - the biological species concept can be applied to asexual organisms

A

false - it cannot

24
Q

define the morphological species concept

A

a species as a group of organisms that share a certain degree of physical similarity

25
Q

when can we assume that the fossil specimens belong to the same species

A

if their physical similarities are consistent with what is expected

26
Q

what are the two factors that make the morphological species concept tricky to apply

A

ontogenetic changes and sexual dimorphism

27
Q

define the differences between lumpers and splitters

A

lumpers - paleontologists need more differences before they consider two species to be distinct

splitters - paleontologists need less differences before they consider two species to be distinct
