Question

according to the following diagram monotremes marsupials and placentals have the same known as a _______ therapsid

Answer 1

Do you have the diagram? I know what monotremes marsupials and placental are, but not so much therapsid

Answer 2

hmm it just has pictures

Answer 3

it says therapsids are mammal like reptiles

Answer 4

i think maybe distant ancestors?

Answer 5

your question says "same known as a...", which doesn't make sense because it doesn't tell you what the "known" is. Not sure if mistype on your part

Answer 6

how it's worded, it looks like it wants to describe a certain type of therapsid. However, I think it's miss worded:

Answer 7

"according to the following diagram monotremes marsupials and placentals have the same known __________ as a therapsid" makes more sense to me

Answer 8

hmmm

Answer 9

in which case, I think it's likely safe to assume it is same ancestor

Answer 10

I would think the diagram is just a phylogenetic tree

Answer 11

common ancestor?

Answer 12

Yeah, what grade are you in?

Answer 13

wait then wat would "similarities in the early development of chickens and opossums suggests that these share a ______" be????

Answer 14

Do you have a word bank?

Answer 15

yes

Answer 16

common ancestor natural selection homologous structures speciation
gradualism artificial selection fossil records overproduction
evolution body distant ancestor older
equilibrium inheritance punctuated equilibrium reproduction isolation
adaptation variation vestigial structure environmental pressures

Answer 17

.-.

Answer 18

vestigial structure maybe? I don't know if opossums have vestigial structures. Since therapsids are old, they might have eventually evolved to have vestigial structures

Answer 19

sorry, I don't know

Answer 20

:c ok
