Because it allowed vertebrates to be free from needing to be near standing bodies of water where they could lay their eggs.
Reptiles are thought to have developed after the evolution of an amniotic egg, which allowed them to reproduce successfully on land without the risk of the egg drying out. This adaptation was a key factor in their ability to transition from an aquatic environment to a terrestrial one.
Variation results from the combination of genetic material from the sperm and egg during fertilization. Each sperm and egg carries a unique set of genes, leading to genetic diversity in the offspring. This genetic variation is important for evolution and adaptation in a population.
The platypus is in the mammal classification. It is a monotreme, or egg-laying mammal.
Calcium is the most important mineral found in egg shells. It is essential for the formation and strength of the egg shell, providing structure and protection for the developing embryo inside.

Birds are winged, bipedal, warm-blooded, feathered, egg-laying, vertebrate animals.
1. An amniotic egg.An amniotic land in an egg that can survive on land. The evolution of the amniotic egg allowed vertebrate land animals to move away from water bodies. They were previously tied to bodies of water because their eggs could not survive on dry land.
A bird is a warm-blooded, egg-laying, feathered vertebrate. Penguins are flightless birds.
The egg that Riley gives you hatches into a Riolu, the pre-evolution of Lucario.
the chicken
Mammals has these 3 groups .
It is a vertebrate because it has a spinal column in its skeletal system. Also it is a mammal, although it lays eggs, and every mammal (or other warm-blooded creature, like a bird) is a vertebrate.
Iguana comes under phylum vertebrate and class reptile and is also a oviparous animal so it lays egg and give birth to their young ones
If you believe in creationism, it was the turkey. If you believe in evolution, it was the egg.
