Ability to adapt.
they both die
Theory is they change slowly over time as they adapt and the ones that can't die out.
Organisms need to evolve in order to adapt to changes in their environment and improve their chances of survival and reproduction. Evolution allows organisms to develop beneficial traits that help them better compete with other species and overcome challenges in their surroundings. It is a natural process that enables species to gradually change over time in response to evolving conditions.
Many species of gnats do not die after mating; in fact, they can mate multiple times throughout their lives. However, some species of insects, like certain types of mayflies, do die shortly after mating as part of their life cycle. In general, whether gnats die after mating depends on the specific species and its reproductive habits.
Bc if Bella is pregnant w/Renesme she cannot determine whether Renesme is gonna live or die during labor and same w/Bella she can't determine whether is gonna live or die during labor.
Humans will not die out because of climate change. Humans like all other biological species will evolve. We will also adapt to our changing environment.
New species evolve from a previous existing species. As challenges arrive in the environment of the old species over many many generations body features are lost and/or gained. Eventually the old species will either eventually die out or change habitats. So basic evolution.
The two main processes that determine the world's current biodiversity are speciation, where new species arise through evolution, and extinction, where species die out due to various factors such as changes in the environment or competition with other species. These two processes continuously shape the diversity of life on Earth.
well your start off point and how high it is will generally determine whether you live or die. the higher up it is the less likey your chance of survival is.
As they live the organisms comprising a species will age and die, they therefore need to reproduce (have babies) in order to replace the members of the species that die or the species will cease to exist (become extinct).
Some species are used to being domesticated, such as dogs and cats, so life without humans might contribute to some species starting to die out. However, these creatures might evolve to the changes over the years. Also, many species are endangered only or mostly because of humans. Those species might actually profit from the change, but we'll never know.
reproductive isolation: the gene pools of two populations must become separated for them to become new species. As new species evolve, populations become reproductively isolated from each other.
