Darwin referred to species that appear to have remained largely unchanged for millions of years as "living fossils." These organisms, like the coelacanth or the horseshoe crab, exhibit very little morphological change over geological time, suggesting they have successfully adapted to their environments without significant evolutionary alterations. Their stability often indicates that they occupy a niche where little change is necessary for survival.
The main difference between the typological species concept and the morphological species concept is that the typological species concept classifies organisms that share characteristics that set them apart from others, whereas the morphological species concept classifies them as the same species if they appear identical.
There is a slang phrase that says fat as a tonky pig. However, this type of pig does not appear to be a true species of pig.
The Giant Panda has 42 chromosomes.
Crocodiles first appeared around 200 million years ago during the Mesozoic Era. They are ancient creatures that have remained relatively unchanged over millions of years.
Mammals were the most important animals to appear during the Cenozoic era. They diversified and evolved into a wide range of species, many of which still exist today. Mammals became dominant on land, adapting to various environments and playing key roles in ecosystems.
I wouldn't know for sure but I think its Ancient Moderns
they appear because they are extinct
545 millions years ago
Humans evolved over millions of years from earlier hominid species. The process of evolution involved gradual changes in physical and behavioral traits that eventually led to the emergence of modern humans.
The early bacterias. Hominids
The differentiation between males and females likely appeared early in evolution, as a means of sexual reproduction. In many species, including humans, the presence of distinct sexes dates back millions of years to the early stages of evolution. The exact timing may vary depending on the species in question.
It varies, but they appear to last millions to tens of millions of years. The Hawaii hot spot is at least 80 million years old.
they were first noticed millions of years ago during the dinosaur time
A pattern of speciation in which most species in an area appear at the same time
A pattern in which most new species appear at about the same time.
the word don't b afraid apperes millions of times!
No. Canids did not appear a few tens of millions of years after the end of the age of the dinosaurs.
