All vertebrate embryos look roughly the same, showing that they come from a common ancestor.
Humans don't ever really look very pig like during development. There are early periods in development where pig and human embryos look similar but by the time human and pig fetuses have developed to the point of looking even somewhat like their future selves they in no way resemble each other.
yes

Yes they do. Echinoderms, which include starfish, and chordates, which include humans are closely related in an evolutionary sense due to the way their embryos are formed in the early stages of development. Once past that point, the very obvious differences form.
Embryology
embryology
The study of embryos is called embryology.
The development of a fruit fly is egg to embyro and then through three larval stages before it pupates and develops into an adult. A larva is an undeveloped worm like eating machine that in no way resembles the adult. The development of frogs varies by species but the most well known cycle is egg to embryo to fetus which hatches as a tadpole and subsequently metamorphoses into a young frog resembling an adult. While a good portion of a frog's development occurs after the egg has hatched the complexity of a tadpole as compared to a fruit fly larva is considerable. The development of a human embryo occurs entirely in the mother's womb with the resulting offspring born resembling the parents. Since both the frog and the human are vertebrates their developmental biology is significantly closer than either would be to a fruit fly.

they study the embryos and they also see if their alike or not alike
Related species have similar embryos.

The stages of development of the embryos of certain organisms are extremely similar, a fact that suggests the organisms had common ancestors.
Embryology is an area of biology that studies the development of embryos. This area is also a part of medicine.
