Biological changes occur based on natural selection. A species changes to best fit its environment. If an organism in a certain species is born with an effective trait (say, a tail, or more teeth, etc), then it will survive to reproduce and pass on that trait. Eventually that trait will be passed down through generations, and it becomes widespread. As the environment for a species changes (climate, food sources, etc.), the members of that species who are best fit to survive in those conditions ultimately end up being the ones that reproduce.
Revolution
Scientists predict that climate change will lead to "weather events" that are more frequent and more severe.
An example for the dwindling number of many species would be deforestation. The events of deforestation have been escalated due to climate change, and have greatly diminished the habitats of many species, making it hard for them to survive.
a kind of lead that compares two events.
Bottleneck events are not always caused by the death of most of a species population. Bottleneck events can be caused by man hunting a species too much, habitat destruction, or an environmental disaster.
The mau movement is lead to the progressive movement!
Some types of evolution are;1. Macroevolution: large evolutionary change, evolution of new species from a common ancestor, evolution of one species into two or more2. Microevolution: small scale, change in gene frequencies within a population over time, changes in population accumulate, they can lead to a new species
small changes add up over time
because lead can kill some animals
The decrease in competition between species can lead to the sudden appearance of many new species because by the time there is a decrease between species more species are developing and that is causing more species to appear so suddenly.
There were many events that took place that lead to the US declaring war on Germany. These events include the sinking of the Lusitania in 1915 and the telegram that Zimmerman sent to Mexico by Germany in 1917.
