What else can I help you with?
When one group of organisms gives rise to several other groups of organisms the original group is referred to as?
a common ancestor.
What were the dominant organisms in the mesozoic era?
The dominant organisms in the Mesozoic Era were dinosaurs, which ruled the land, along with marine reptiles and ammonites in the oceans. In the later part of the era, mammals and birds began to diversify and emerge as important groups of organisms.
What does speciation create?
Speciation creates new species by splitting a single population into two or more groups that evolve independently over time, leading to genetic differences and the formation of distinct species. This process is important for biodiversity and allows organisms to adapt to different environments and ecological niches.
What is a part of process of speciation?
Speciation is the evolutionary process by which populations evolve to become distinct species. A key part of this process is reproductive isolation, where groups within a species become unable to interbreed due to various barriers such as geographical separation (allopatric speciation) or behavioral differences (sympatric speciation). Over time, genetic divergence accumulates due to natural selection, mutation, and genetic drift, leading to the emergence of new species. This process can take thousands to millions of years, depending on environmental factors and the organisms involved.
It is difficult use the criterion of interbreeding to define species of unicelular organism why?
it is difficult to use criterion of interbreeding to define species of unicellular organisms because not all organisms undergo the same process. these species come from the class and groups thus making it even harder.

Dominant organisms in tertiary time period?
During the Tertiary period, dominant organisms included early mammals, large birds, marine mammals like whales and dolphins, and diverse plant species. This period saw the rise of modern mammals, along with the evolution of grasslands, forests, and flowering plants. The Tertiary period also saw the decline of dinosaurs and the rise of more familiar animal groups.
What is it called when separated groups of a population Kaynak mate with each other?
It is called speciation.

What are six major patterns of minority and dominant groups?
Assimilation: Minority groups adopt the values and norms of the dominant group. Pluralism: Both minority and dominant groups maintain their cultural identities and coexist peacefully. Segregation: Separate social structures for minority and dominant groups with limited interaction. Genocide: Systematic destruction of a minority group by the dominant group. Legal protection: Laws are enacted to protect the rights of minority groups. Internal colonialism: Exploitation of minority groups within the dominant group's society.

What did the Americanization movement of the early twentieth century seek to do?
assimilate ethnic immigrant groups into the dominant culture
What are the 5 groups of vertebrate organisms?
Vertebrate organisms are organisms that have a spine. The five groups of vertebrate organisms are mammals, birds, amphibians, fish and reptiles.
What would most likely increase the rate of speciation in the population?
put the two groups in different enivorment apex
What is the name for a complex organisms groups of organisms?
