Scientists have unearthed 13 fossil teeth in Ethiopia’s Ledi-Geraru region that reveal a previously unknown Australopithecus species living 2.6–2.8 million years ago. Ten of the teeth belong to this new species, while three come from early members of the genus Homo, showing that the two lineages shared the same habitat.
The discovery, detailed in Nature on 13 August 2025, adds to evidence that human evolution was not a straight line but a "bushy tree" with overlapping branches.

Hey everyone! 👋
I was planning to create a contest on LeetCode, but since that wasn’t possible, I’m considering hosting it on Codeforces instead.
✨ What do you think about this idea? 🤔 How many of you would be interested in joining?

So we will have 2 contest in a week as some of u suggested, even though it wasnt majority idea , adding one contest doesn't go against that since it is another opportunity. So the contest will be held Thursday and Sunday 7 pm(1 Local time)
If u have any idea or question comment it down

In prev Contest Some of you were directly submitting questions on Codeforces without testing. This often leads to wrong answers.
👉 But there’s a way to test your code first in VS Code using CPH (Competitive Programming Helper).
How to use CPH:
Install CPH extension on your browser (Chrome Web Store).
Install CPH extension in VS Code.
Open a Codeforces problem → click the + icon and go to vs code
select language
Write your solution in VS Code.
CPH runs it with the samples.
✅ If all pass → submit on Codeforces.
