Around 100,000 years ago there was a second hominine species closely related to modern humans, Homo <span><span>neanderthalensis,</span><span> or commonly called the Neanderthal</span>.</span> Recent studies of neanderthal DNA have shown that there is 3-4% of their genes in modern humans outside of Africa, mostly from Europe, including the ones for adapting to the cold and vitamin D absorption.
The liver can regenerate up to half of itself
For evolution to occur:
There must be genetic variation in a population. This provides variation on which natural selection can act. Then natural selection can act by selecting those species which are better adapted to the environmental conditions. Over time those animals that are best suited to the environment only will survive and reproduce. Those organisms successful genes will be preserved and eventually the gene frequency in the population will change, changing the overall characteristics of a population. This is how evolution occurs.
It means, process of eliminating waste matter..
Answer:
The ecosystem will become sick and die.
Explanation:
The toxic waste can travel to other bodies of water, whether it be a river or waterfall. This can contaminate and poison the water, as well as the organisms living inside it. This will harm fish, birds, plants, animals that drink the water, etc.
