Overproduction/overpopulation, Inherited variation, Struggle to survive, Successful reproduction
Successful reproduction is the key to natural selection because organisms must survive long enough to be able to reproduce and pass on beneficial traits. Beneficial traits need to be passed on because they are adaptations. Share out examples!
Adaptations help an organism survive and reproduce because an adaptation is a trait that is well suited to a particular environment. If an animal is well suited to their environment they will survive longer and reproduce. Examples?
Structural Adaptations are the physical features that help an organism survive. › An example is camouflage. Behavioral adaptations are the things organisms do to survive. › An example is stalking prey. These adaptations can be used together. For example, a leopard stalks it’s prey, and it’s spotted coat allows the leopard to avoid being seen because it blends in with the environment.
H- Habitat Loss I- Invasive/Introduced or exotic species competition L- Loss of Genetic diversity/variation L- Lack of ability to adapt
Humans impact the extinction of other species mainly due to habitat loss/destruction. Humans contribute most to this because of the demand for more space and resources. › Humans cut down trees for their needs, humans reroute rivers causing desertification, humans introduce exotic species which can become invasive, humans destroy habitats to build homes, buildings, etc...
Habitat loss. It is such a problem because humans are constantly changing environments.
De-extinction is bringing back extinct species by using their DNA to clone. Good Idea: can give us more information about them, can possibly help with the development of new pharmaceuticals, the technology becomes cheap fast which could have benefits…etc… Bad Idea: Waste of money (clones don’t always survive), could introduce new virus/disease that we can’t fight, could become invasive, no environment to put the species…etc…
Climate change, using all of our resources, nuclear war, pandemic, meteor strike, complete destruction of the planet…etc… Do you think it will happen?
