The chart below shows three different stages of embryonic development for three different animal species. Stages of Development of Three Animal Species
species 1
species 2
species 3

this stage have gill slits and a large embryonic tail.
What do these similarities most likely indicate?
A. All three species evolved in the past 100 years.
B.
All three species look very similar as adults.
C.
All three species share a distant common ancestor.
D.
All three species evolved from a single mammalian ancestor.

Cattle with brown fur and cattle with white fur will produce a reddish roan calf . when examined closely, the calf show about an even number of brown hairs and white hairs that give a reddish appearance when viewed from far away. the fact that both the brown fur allele and the white fur allele are expressed equally in the offspring is an example of
