Why did hominids die?
There were many factors that contributed to the extinction of various hominid species, such as environmental changes, competition with other species, and possibly disease or genetic factors. Changes in climate, habitat loss, and new predators may have played a significant role in the decline and eventual extinction of some hominid species.
Why did australopithecus die out?
The exact reasons for the extinction of Australopithecus are unclear. However, factors such as climate change, competition with other species for resources, and environmental changes may have played a role. Additionally, their limited ability to adapt to changing conditions could have contributed to their eventual extinction.
What best describes Darwin's theory of evolution?
Darwin's theory of evolution, also known as natural selection, posits that species evolve over generations through the process of selection of advantageous heritable traits. This theory explains how organisms adapt to their environments and how new species arise through the accumulation of small, gradual changes. Darwin's work revolutionized the field of biology and has had a lasting impact on the understanding of the diversity of life on Earth.
What are topics of macroevolution are?
Topics of macroevolution include speciation (the process by which new species arise), adaptive radiation (the diversification of a group of organisms into different forms), evolutionary trends (long-term patterns of change in a lineage), and extinction events (massive die-offs affecting a wide range of species).
When did the Cro- Magnon die out?
The Cro-Magnon, classified as early modern humans, did not die out as a distinct group; they are considered the same species as modern humans. Their lineage evolved over time into what we are today.
Why do animals and other things to reproduce?

They can come along and eat other animals, which can die out. They might take other animals food and other animals die out. There is positives. There is more food for e.g. a fox so more rabbits are born.

because rhinos are part of the food chain. they eat smaller animals which eat other animals and so on. so if we get rid of one species then all the other animals will die therefore we wont have any meat so we will die
What types of human activity decrease species diversity?
When people destroy the home's of animals and we build house's and other biuldings which then animals have no homes and will die.
Does animal testing threaten species?
Yes because lots of animals die from animal testing witch lowers that animals species
What happens in an ecosystem after a species dies?

Why the animals like smilodon are not in the Earth now?
I think you mean extinct animals, and they die out from over-hunting, loss of habitat, no more food, alien species, or other things.
How does the endangered species affect the native food web?
Well, if one species of animals die out, then the following species that would have eaten it would die out , too. Why? Because they're not getting enough food for energy. This goes on, and on, and on, and it affects the population of animals.
What can happen if one species become extinct?
It messes up the food chain and other animals can die E. R. I.
