Likewise, grafting mouse mouth tissue into a developing chick embryo demonstrates how Hox genes work across different animals; the resulting chicks hatch with teeth, though the teeth look dinosaurian. The authors hypothesized that shrinking size might have been driven by bird ancestors taking up residence in trees, perhaps to avoid predators on the ground. But these situations are rare. And then there are genes that manage the big picture in a variety of organisms. Sexual Selection - increase reproductive success. In the end, the origin of life remains a mystery that passes understanding. Once in the water, many more baby turtles become snacks for their neighbors in their new watery neighborhood. One scenario is that metabolism came first; simple molecules powered by chemical energy from minerals preceded genetic material. But scientists like Albert Oppel hit upon the same principles at about about the same time or earlier. In casual conversation, we talk about our "theories" all the time, i. The observation that fossils occur in a consistent succession is known as the "principle of faunal and floral succession". They spurred little reaction, but a year later, Darwin published The Origin of Species.
