42C+42A=2310
12A=420
A=35
we will find children ticket next
42c+30a=1890
30c+30a=1650
12c=240
C=20

Scientists infer evolutionary relationships by comparing the early development of different organisms by phylogeny.
In scientific terms, the evolutionary relationship and history of an organism or cluster of organisms is termed its phylogeny. It describes the relationships of associate organism, like from that organisms it's thought to own evolved, to that species it's most closely connected, so forth.
Scientists collect information that enables them to create evolutionary relationships between organisms. Almost like a detective work, scientists use proof to uncover the facts. Within the case of phylogeny, evolutionary investigations specialize in 2 styles of evidence which are morphologic and genetic.
