How are new spiecies created?
If two or more populations of a single species are separated geographically, whether by mountain ranges, oceans, deserts or even small valleys, they will, over many generations, change to become different from the other populations, assuming there is no physical contact between them. This is due to mutations, which occur every generation, being acted upon by the different environments the populations find themselves in.
How do regulations protect fish populations in oceans?
Regulations protect fish populations in oceans by allowing certain seasons for fishing different species. Shrimpers for instance, have a few months in which they are allowed to have their nets in the water. In my state, if you catch a Red Fish under 24 inches or over 36 inches you must release them. These regulations are important to protect their population and allow fish for our future generations.
How do sharks stay alive?
There are many different species of sharks in our oceans. Each breed has a different expected length of life.
Where do jellyfish live in the world?
Different species Jellyfish can be found in all the oceans across the world.
How is it possible for one species to live in all the worlds oceans?
One species adapted to all the worlds oceans
What are the geographical barriers that contribute to the process of speciation or natural selection?
Geographical barriers such as mountains, oceans, rivers, and deserts can prevent gene flow among populations, leading to reproductive isolation and eventually speciation. These barriers create isolated environments where different selective pressures can act, driving the evolution of distinct traits in separated populations. Over time, these differences can accumulate, resulting in new species adapted to their specific environments.
Where would a researcher most likely find examples of allopatric speciation?
A researcher would most likely find examples of allopatric speciation in geographical areas that have physical barriers, such as mountain ranges, rivers, or oceans, that separate populations of a species. These barriers prevent gene flow between the populations, leading to genetic divergence and ultimately the formation of new species.
Is there any scientific proof that orcas are different species?
Scientists report finding strong genetic evidence supporting the theory that there are several species of killer whales in the world's oceans.
Which ocean do jellyfish live in?
Different species Jellyfish can be found in all the oceans across the world. == ==
In oceans fish populations live in schools that live and feed in the same area?
Clumped
Were do star fish live?
In the sea and oceans. Different species live in different marine habitats, some living in rock pools, coral reefs, sandy or weedy areas.
Where dos the flying fox bat live?
There are about sixty species of flying fox. Different species live in different areas. Flying foxes as a whole live in the tropical rainforests of Asia and Africa, as well as on certain islands in the Indian and Pacific oceans.
