| 释义 | 物种 The Origin of Species; In many species, humans included, it passes only from mother to child. No paternal genes get mixed into it. They have been the subjects of intense research for over half a century, not least because of the role they have played in our survival as a species. Darwin stated that the species originate by descent. But it was on the Galapagos Islands off the coast of Ecuador that Darwin found creatures that made him wonder about how species develop and change. But thinking of my husband as an exotic species gave me the distance I needed to consider our differences more objectively. And no other species does anything at all like it. You know, why don't we just leave half the species here. If we are serious about coexisting with other species, we have to concede them territory. If we want to survive as a species, we have to expand into the solar system and likely beyond. If these species are not defined by interfertility, which obviously they are not, are they real, or just the convenient conventions of taxonomists? So the mystery is starting to clear around how diverse species with an array of features evolve. All the living beings spring from species, Future research, he says, should look at the behavior and ecology of these worms to understand what caused the new species to arise. They also converted one species of bacterium into another through a “ genome transplant”. I can give you many examples in which one member of a species has different genes than does another. I believe they were a subspecies of human but not a different species. Many species are in peril of extinction because of our destruction of their natural habitat. The researchers say that one day these cells could be turned into sperm and egg cells to bring the species back from the brink. Since any species that could visit us would be far beyond our own technological level, meeting them could be bad news. Since all instinctive behaviors have an evolutionary advantage or they would not have been retained for millions of years, chances are that this one too has helped us survive as a species. All this suggests that the formation of both languages and species is an active process. This means that many of these species could have disappeared before even being discovered. The female of the species is very aggressive. Diets of these beetles vary from species to species. Then they counted the species above it. One person goes on to the next round of the species, and the other goes to the grave a loser for all eternity. |
