Sloths are not extinct.
one major species was the extinct lemur. they've been extinct for minutes.
Because of the morphological homologies they display with similar structures in other extant and extinct lifeforms, following, like virtually every other morphological or anatomical feature of life, the nested hierarchies of biology.
no.they are almost extinct they are very rare.
Yaks are not extinct although they are an endangered species
Fossils that provided insight into the theory of evolution
It was based on fossil evidence
Fossils provide physical evidence of extinct organisms and show a progression of forms over time, supporting the concept of evolution through natural selection. Biochemicals, such as DNA and proteins, can be compared between different species to reveal shared genetic sequences, indicating a common ancestry and supporting the theory of evolution.
Evolutionary theory explains virtually everything about the diversity of life, everything we know about life, of extant forms as well as extinct. As the geneticist Theodosius Dobzhansky wrote: nothing in biology makes sense except in the light of evolution.
he believed that species better suited to their enviornment lived and reproduced while those not suited died off and eventualy became extinct(survivel of the fittest)
Divergent Evolution :)
No, there are mushrooms everywhere. However I am certain some species of mushrooms have gone extinct over time, it is part of evolution.
i think it is .but it is my extinct and i cant explain.
Evolution
The large rodents became extinct due to evolution. This can happen to many different types of animals not just rodents.
The theory of evolution is that species aren't fixed; new species can evolve from existing species. The earliest recorded theory of evolution dates back to the ancient Greeks - Anaximander in 650BC proposed that life originated in the sea and later moved to the land. The theory was postulated again in the 18th century; fossils had been discovered of extinct animals - including of "primitive" forms of modern animals. At the time, multiple floods were proposed to explain fossils of extinct animals - although it was never explained where all the water went in between floods! The discovery of fossils of extinct animals with fossils of existing animals was very hard to explain with flood theory - how could some animals survive a flood and others not? To explain evolution several theories have been proposed; Larmarck suggested that offspring inherited characteristics from parents that they had acquired during life - for example, giraffes stretching to reach high leaves on trees grew longer necks - the longer necks were passed on to their offspring. The problem with Larmarckian evolution is that there wasn't a mechanism to explain how acquired characterstics could be passed on; if you have a scar on body from an injury, your children aren't born with the same scar. It was the careful research of Charles Darwin and Alfred Wallace that led to the natural selection theory - which provides a mechanism for evolution. Darwin, in particular, provided a large amount of evidence to support the theory.
Through evolution, loss of natural habitat and environmental changes.
