Can other kinds of animals evolve like us? And can
humans evolve more? |
Question Date: 2016-08-31 | | Answer 1:
Humans are animals. We aren’t any more
evolved than any other species, but we evolved
down a different path from other species, just
like foxes evolved down a different path than
raccoons.We are not monkeys, but we share a
common ancestor. We are primates, meaning that
we have thumbs that can touch all of our other
fingers (opposable thumbs). Our eyes are in the
front of our faces, so we can see in 3D. We
did not evolve from any of the other primates that
are still around, but we came from species that
lived millions of years ago and had several
branches on their family tree. If you go back
far enough, you would even find an ancestor that
we shared with modern fish, but we didn’t
evolve from any fish that are still around.
All living things can evolve. Evolution just
means a change in how common certain genes are.
The changes can be small. If populations get
separated long enough, they can change in ways
that eventually make them new species. Humans
haven’t necessarily stopped changing, but it’s in
very small ways. The longer the lifespan is in a
species, the longer it would take to see a change.
Humans are all one species. In order for humans to
split into new species, a group of humans would
have to be isolated somewhere for tens or hundreds
of thousands of years, maybe some lost space
colony someday will do that.
Having a big brain is a big part of being
human, but that doesn’t mean that other species
will get bigger brains (Some big animals
already have brains bigger than ours, but for
our body size, are brains are big and
complex.) Having a big brain costs a lot of
energy. Other species are successful by being
stronger than we are, or smaller, or faster.
Having a bigger brain might actually lower their
survival. Birth is already difficult in humans
because of our big heads.

Thanks for asking, | | Answer 2:
All animals, including humans, are still
evolving. Humans are not the end of evolution.
However evolution is not a one-direction march
toward progress: it is unlikely that there will
ever be another animal that is quite like us. They
will evolve in their own new and wonderful
directions. | | Answer 3:
One of the amazing things about evolution by
natural selection is that it applies to all
life – humans, animals, plants, fungi,
viruses, etc. All life is evolving over time,
including us.
Let’s take a closer look: Each
individual in a species is born with some
combination of their parents’ traits and some
random new ones. If some of those traits make it
easier to survive in their environment, that
individual will live long enough to pass their
traits to their children. This natural selection
leads to change over time, a process we call
evolution.
For example, sparrows fly slightly
faster than other birds in their area so they can
catch more food. Quails, on the other hand, are
able to hide from predators more easily. Both are
ways to survive in the same environment. The
examples above are very simple; in reality, not
all traits directly contribute to survival, so
they continue to be passed on at random.
Evolution is simply change over time, with no
preferred way to survive or best traits. All
the animals that live with us on this planet have
survived and are equally evolved to live in their
specific environment.
Humans and animals are constantly
evolving but the process is slow and hard to
detect as it’s happening. Take a moment to
think about all the things that humans can do –
which traits do you think are important to our
survival?
| | Answer 4:
All kinds of plants and animals are always
evolving. Everything evolved from organisms that
lived about 3 billion years ago and only had 1
cell. Everything is still evolving. Some
living things still only have 1 cell, but they are
still evolving, just like us and plants and all
the other animals.
