researchers have recently found that DNA
0:29
inherited from meanderthals might be
0:31
linked to autism in modern humans let's
0:34
break it down around 40,000 to 60,000
0:38
years ago our ancestors Homo sapiens met
0:42
and interbred with neanderthals as a
0:45
result we share about 1 to 2% of our DNA
0:49
with these ancient relatives scientists
0:52
from Clemson University and Lola
0:55
University in the US have discovered
0:57
that some of this Neanderthal DNA is
0:59
present in genes associated with autism
1:02
spectrum disorder or ASD the study
1:07
3,442 people with and without autism
1:11
researchers have discovered that genetic
1:13
combinations polymorphisms that were
1:16
shared with Neanderthal in our DNA are
1:19
present more frequently in autistic
1:21
individuals they also uncovered 25
1:24
genetic combinations involved in brain
1:27
development that were found in 67 % of
1:30
autistic people with epilepsy and only
1:33
22% in people without autism this
1:37
suggests that certain genetic traits
1:39
from meanderthals might influence the
1:41
likelihood of developing ASD the team
1:44
emphasized that autistic people who have
1:47
these sets in their DNA have the same
1:49
amount of Neanderthal DNA as non
1:51
atistics it is the combination of the
1:54
DNA inherited that plays a role
1:57
scientists say that studying the DNA We
2:00
inherited from neanderthals we can gain
2:03
insights into the genetic factors that
2:05
contribute to autism and potentially
2:07
other neurological conditions it's
2:10
important to remember that autism is
2:12
influenced by many factors both genetic
2:15
and environmental the Neanderthal
2:18
connection is just one piece of a very
2:21
complex picture if you found this video
